5. Scope of Services
5.1 Proposed Solution
To meet the needs of the Town of Los Gatos, we are proposing a solution based on Econolite’s industry-leading
Centracs ATMS being used in conjunction with Econolite Cobalt ATC controllers running Econolite’s leading-
edge controller software, EOS. Given Econolite’s vast experience serving as the Town’s traffic signal
management provider for many years, there could be no better partner to help the Town manage the
challenges of a phased traffic management infrastructure improvement strategy. A detailed description of our
ATMS, ATCS, and controller solutions, is presented in the following sections. In addition, product datasheets
have been included in the Appendix.
5.1.1 Centracs ATMS Overview
Centracs is a state-of-the-art ATMS platform
that satisfies immediate project requirements,
supports the objectives envisioned by the
Town, and provides a hedge against early
obsolescence by continuing to meet the Town’s
needs well into the future.
Econolite is excited about the opportunity to work with the Town to deploy Centracs. Centracs is a powerful,
groundbreaking system that is easy to deploy, easy to learn, and easy to use. Centracs is rife with innovative
features and is distinguished from the field of ATMS solutions in five key areas: innovative software technology,
smart client architecture, the ability to easily add enhancements and expand the system, an intuitive user
interface, and an incredibly rich feature set.
5.1.1.1 Innovative Software Technology
Centracs is built upon the latest software technologies, including the Microsoft .NET Framework, Windows®
Presentation Foundation, and Windows® Communications Foundation. As a result, Centracs provides the Town
with a barrier against obsolescence. In fact, since its introduction, there have been 15 major releases (Figure
3), each adding significant new features, including adaptive control, enhanced measures of effectiveness
(MOE), enhanced Closed Circuit Television (CCTV) support, and Dynamic Message Sign (DMS) support.
5.1.1.2 Smart Client Architecture
Centracs utilizes a client-server architecture. A client-server system architecture is not new, but the
segmentation of the system components is what makes Centracs unique. By encapsulating the user interface
at the workstation, the interface is responsive, even over lower-bandwidth connections. The “core” server
provides all the central ATMS functionality, such as system administration, schedule functions, system alerts,

user settings, traffic responsive, and adaptive algorithms. A data abstraction layer on top of the Microsoft SQL
Server database serves as a broker for all data requests throughout the system. Communications servers
handle the real-time device messaging and network interface. This logical segmentation of the components
provides tremendous scalability for the system, allowing the Town to easily expand into the future.
5.1.1.3 Expansion and Enhancement
Centracs is not only easy to use for day-to-day operations, it is also extremely easy to expand support for
additional devices. All system data is entered through the user interface. There are no .ini configuration files
to edit manually, no direct interaction with the database, and no system restarts for most configuration items.
Whether adding new devices, new users, or even additional communications servers, there is an intuitive
graphical user interface (GUI) to assist the system user. With Centracs, we have included access to virtually
every configurable element within the interface so that users can expand their own systems without requiring
additional outside services.
As for enhancements, the latest version of Centracs software is provided annually (or more often if patch
releases are needed) at no additional cost, as long as the software maintenance agreement is current.
Centracs represents a great value, as it ensures you always have the most current technology. Additionally,
Econolite continues to invest in Centracs to offer our customers the best in ATMS technology today and into
the future. Of course, if custom software enhancements are required, Econolite offers software development
services to meet unique customer needs as well.
Econolite maintains one version of Centracs among all our 300 deployments. This ensures quality of product
and a consistent experience among our entire user base, such that users are not orphaned with a “one-off”
system. Features that are developed for a singular agency are typically developed in a way that provides value
to all users. In some rare cases, features have been developed for one agency that do not have this broad
applicability. In those situations, the features are provided as a modular selection so that other users who do
not need this support, do not experience the clutter of unneeded modules or interfaces (e.g. support for
Houston’s HOT Lane reversible lane controller).
5.1.1.4 Intuitive User Interface
The Centracs user interface is unique to
the transportation industry and
capitalizes on the latest Microsoft
Foundation Class technology. While the
interface can best be appreciated in a live
demonstration, the screenshot shown in
Figure 4. gives an idea of how the
interface uses “containers” to present a
wide variety of data elements in an
organized fashion. With full multi-monitor
support, the system supports additional
frames that can be assigned to each
monitor. Additionally, each user can save
one or more preferred configurations and
restore their unique preferences when
logged in.

Beyond the rich information content and flexible displays, the Centracs interface allows both expert and new
users to be efficient and effective through context-sensitive menus, on-line help, and map and entity selection
allowing users to easily navigate and effectively use the capabilities of modern controller technology.
5.1.1.5 Rich Feature Set
Econolite has been in the transportation management business for over 85-years. Over this time, we have
learned many lessons, but one critical lesson is that no two users are exactly alike. With this in mind, we have
designed Centracs to be standards-compliant while still offering users the ability to customize their user
experience in a virtually unlimited number of ways. Since its introduction, we have released fifteen major
updates adding additional capability and enhancing the existing feature set. Most of our new features are
packaged with the core software and are provided at no additional cost to users under maintenance
agreements.
System Map Interface
The main map and intersection graphics display is an integrated part of the system and is not a stand-alone
application. The system automatically updates the status of all devices on all map displays once-per-second
as data is retrieved from the field devices.
Centracs incorporates an interactive Statewide map as the foundation for the main graphics display. The map
can be displayed in any or all the available Centracs “containers” simultaneously or individually. Each instance
of the map display is set up independently by panning and zooming such that each map region can be utilized
as an individual sub-area for monitoring individual intersections or groups of intersections.
Centracs maps are rendered dynamically using geo-coded Geographic Information Systems (GIS)-based map
data. The Centracs system comes preconfigured with rendered map “tiles” generated from geographically
accurate HERE map data. HERE map data provides the most accurate street-level rendering capabilities for
the Centracs map interface. Street curves, corners, and other geographic entities are depicted accurately and
without distortion. The display also
supports bitmap (.BMP), JPG/JPEG,
.PNG, and .GIF raster file formats,
ESRI shape files, and SDE version
9.x.
Additionally, Centracs supports
Web Map Services (WMS) to display
geo-referenced map images from
any WMS source, including ESRI
ArcInfo Enterprise, if available and
properly configured.
Zoom level ranges are configurable
such that the display of dynamic
and real-time status data appears
or changes at various zoom levels.
The screenshots shown in Figure 5
represent the four supported zoom
levels of the map interface
including regional, Statewide,
corridor, and intersection level
examples. Figure 5 - Centracs Maps

17
Alarms
Centracs can be configured to send alerts to users based on specific events from field devices or from
components in the system. The existing events are displayed in the Alert Monitor dialog. Centracs receives
“Events” from field devices and other points in the system. These “Events” can be logged, but also can
generate “Alerts” or initiate other actions to occur.
An “Alert” is a notification sent to either an online, logged-in user, or an offline recipient via an email or SMS
text message. A “Trigger” defines how an event generates an Alert or Action and is user definable.
All Centracs users, whether online or offline, can be assigned to receive alerts (Figure 6). Offline recipients are
those individuals that are not currently using the ATMS and therefore require an email or SMS message
notification. In order to send emails or SMS text messages, the email server must be configured and setup
using the Centracs SMTP Servers main menu setup window.
If an alert is not acknowledged or closed within a certain period, the user may “escalate” the alert or send it
to an additional recipient or group of recipients. Centracs allows for this via Alert Escalations.
Traffic Control
Centracs supports five central traffic control strategies that allow the traffic operations staff to ensure the
system is either running its normally scheduled TOD patterns, or dynamically commanding alternate patterns
to meet non-recurrent traffic patterns, special events, or other needs. The following strategies are offered in
order of descending priority:
Figure 6 - Centracs Alarms
Proposal
Adaptive Signal Control and Advanced Traffic Management Systems
for the Town-Wide Traffic Signal Upgrade Program
18
• Manually Commanded / Overridden
• Incident Response Triggered
• Adaptive (licensed per intersection)
• Traffic Responsive
• Time-of-Day (TOD)
These methods of traffic control can be applied in any combination to individual controllers, sections of
controllers, and groups of controllers. Controllers can belong to a single section at any time but can be moved
from one section to another manually or by Time-of-Day. Controllers can also belong to multiple groups at any
one time, offering maximum flexibility in traffic control strategies.
Reports
Centracs provides a full set of reports that provide insight to the roadway conditions as well as operational
status and events within the infrastructure itself. These reports are generated using Microsoft SQL Reporting
Services. Some reports allow for specifying, filtering, and sorting parameters to customize the reports.
Centracs currently provides twenty-nine (29) reports that include information compiled from data retrieved
from the system and any field device capable of logging data. The following is a list of the available Centracs
reports:
• Alerts Log
• Communications Statistics
• Detector Fault Status
• Detector Fault History
• Device Configuration
• Entity Hierarchy
• Entity Notes
• Hourly Comm. Statistics
• Intersection Events
• Links
• Raw Detector Data
• Section Schedules
• Signal Changes
• Signal Detector Events
• Signal MMU Events
• Split Upload and Compare
• Split Monitor
• System Activity
• System Events
• Time Drift
• Time Drift History
• Traffic Responsive
• TSP Summary
• User Login
• Users and Recipients
• VOS Daily Report
• VOS Hourly Report
• VOS Multi-Date Hourly Report
• VOS Multi-Date Daily Report
Centracs also provides a means by which user-specific reports can be created and added to the Reports menu
item without the requirement of additional third-party software or custom development work by the software
provider. Microsoft SQL Reporting Services is provided as the custom report-generating tool.
Adaptive Signal Control
Econolite has introduced a completely new cloud-based adaptive solution using high resolution Performance
Measures datasets. Called Centracs Edaptive, these algorithms were first established within the FHWA
research, but now have been applied on a real-time basis so that the system can adjust cycle length, offset,
and splits to ensure the fastest response to unpredictable changes in traffic demand. We are proposing
Centracs Edaptive as our ATCS solution and discuss this offering in Section 5.1.3 of our proposal.
Optional Centracs Modules
We believe some of the following optional Centracs modules may also be of interest to the Town.
Proposal
Adaptive Signal Control and Advanced Traffic Management Systems
for the Town-Wide Traffic Signal Upgrade Program
19
Dynamic Message Sign (DMS) Management
Centracs supports Dynamic Message Signs, which allows users to manage and control signs and messages
from within the Centracs user interface. The DMS module has a user interface that supports operations for
NTCIP compatible signs, which includes message formatting, true display on workstation, message libraries,
and banned word lists.
Signal Performance Measures Tools
The Centracs MOE module, combined with EOS ATC traffic controllers can collect and store individual detector
information at a 100ms resolution (10 times per second). It also gathers and combines other key data
associated with signal operations and coordination to provide a set of graphical tools that enable engineers
to visually inspect and analyze the performance of traffic timing and coordination.
The Centracs SPM module offers Signal Performance Measures (SPM) analytics, reporting tools, and even
control strategies based on research from the FHWA NCHRP 3-79a program. This research was funded by
FHWA specifically to help transportation agencies become more agile in monitoring and tuning crucial
parameters affecting traffic signal coordination and progression. These tools graphically combine and render
detector and other data specific to traffic signal operation.
Econolite has also enhanced the latest academic research on signal performance measurement and
optimization. We have incorporated the link-pivot optimization algorithms within this research and achieved
the capability for signals to now be automatically re-optimized by the central system. This capability eliminates
the need for DOTs to fund or perform signal re-timing. We discuss this offering in Section 2.2 of our proposal.
Transit Signal Priority (TSP)
Basic TSP is implemented by controllers running Econolite’s ASC/3 and EOS software. TSP functions can be
managed, monitored, and reported via Centracs. Centracs can also provide Route-based Transit and
Emergency Vehicle Priority.
Closed Circuit Television (CCTV)
Centracs is capable of supporting video streaming from RTSP sources directly into the Centracs client
workstation or via integration into a 3rd party CCTV system. Econolite has partnered with Genetec to integrate
their Security Service Video Management software into Centracs. This extended offering provides a robust set
of video management capabilities and is offered as an optional module to Centracs.

Centracs Travel-Time
The Centracs system supports an interface to the data collected by Travel Time systems. This interface
provides automated recognition of new BlueTOAD devices that can display data on the Centracs system maps
by changing roadway colors. It also includes detailed current and historical travel-time reporting for before-
after studies. We are eager to work with the Town to potentially extend the Centracs Travel Time module to
support additional data sources from XML feeds, such as the HERE, INRIX, and Uber datasets.
Centracs Local Edition
Centracs Local Edition allows uploads and downloads from a laptop to locally connected controllers in the
field. It also allows users to modify controller configurations offline from the central system and synchronize
their changes with the main Centracs database when re-connected to the ATMS network.
Server-to-Server
The Centracs Server-to-Server (S2S) module provides a unique interface allowing agencies to achieve
unparalleled benefits through cooperative operations and system management. Adjoining Centracs-managed
agencies can seamlessly share data and manage arterial traffic across agency boundaries, finally realizing
and exceeding the promises of Center-to-Center communications. Centracs Server-to-Server also allows
agencies to participate in cross-jurisdictional management and monitoring of neighboring agency
intersections.
NTCIP Center–to-Center Interface
Centracs supports NTCIP Center-to-Center Interfaces that exchange data objects with other central systems
using published NTCIP objects including the Traffic Management Data Dictionary (TMDD). Data can be securely
exchanged between centers and displayed on each system. This functionality could be used to exchange data
and information between the Town and other regions systems for more efficient management of the State
transportation system as a whole.
Data Collection and Management System (DCMS)
Centracs offers a Data Collection and Management System capability, providing users with real-time traffic
monitoring and travel conditions at intersections, mid-blocks, or freeways via vehicle detection devices, as well
as on-street video detection devices that can be turned into automated virtual count stations that gather traffic
data. This expands support for detectors and other ITS devices that are not connected to a traffic controller.
With DCMS, traffic engineers and planners can obtain up-to-date data they need to make informed decisions
to optimize traffic signal timing and satisfy federal and state data reporting requirements.
Maintenance Management System (MMS)
MMS is a module that can fully integrate with Centracs to provide real-time data entry that tracks all field
activities and assets. This is an industry-specific asset management system that provides document
management, staffing management, inventory control, and more.
Other features include a mobile web interface that allows technicians to enter data in the field, increasing
timeliness, accuracy, and providing real-time status of reported problems and response. In addition, because
of its feature to fully integrate with an ATMS module, MMS can respond to system events by creating a service
ticket (Figure 8) and even dispatching technicians assigned to the affected area or on-call.

5.1.2 Centracs SPM
Verifying and documenting effectiveness of signal
timing can be a monumental and cost-prohibitive
task, particularly with transportation agencies short
of signal retiming resources. Moreover, traditional
measuring tools for traffic studies fail to take
advantage of the comprehensive data now being
provided by modern traffic signal controllers. Signal
performance measures, based on this data, allow for the creation of a new generation of sophisticated analytic
tools that help engineers, planners, consultants, and other traffic stakeholders.
Centracs SPM is a web-hosted solution that is integrated as an
extension to the locally-hosted Centracs ATMS. For each of an
agency’s ATCs, Centracs SPM enables agencies to fully utilize ITS
assets, helping transportation stakeholders visually analyze and
identify the performance of traffic signal timing plans, diagnose
problems, and quickly produce a full spectrum of traffic studies
and reports.
Centracs SPM is a powerful, easy-to-use cloud-based solution that
measures and assesses factors that impact traffic signal
coordination. Centracs SPM provides state-of-the-art analysis
tools, enabling transportation agencies, planning organizations,
and other transportation stakeholders more efficient and effective
use of resources in optimizing traffic signal timing, coordination,
and operations. Centracs SPM provides powerful diagnostic
dashboards, heat maps, and analytical tools that identify problem
areas and enables users to understand what issues are affecting
Figure 8 - Centracs MMS
As further explained in the following
section, our Centracs Edaptive ATCS
solution provides adaptive control
capabilities based on system
performance measures derived from
Centracs SPM. While we recognize that
the Town intends to procure an
Automated Traffic Signal Performance
Measures (ATSPM) system through a
subsequent RFP, later in 2020, as a
value-added proposition, we are
proposing to include SPM features as
part of our proposed ATCS solution for
this project at no additional cost to the
Town.

traffic flow, the traffic signal
changes that need to be made,
and how well those coordination
changes are working (Figure
9Error! Reference source not
found.). Centracs SPM transforms
qualitative and quantitative data
into actionable information. Before
and after charts and reports allow
engineers to know how timing and
other changes affect traffic flow.
Because Centracs SPM is cloud-
based, transportation agencies,
consultants, and MPOs do not
need to purchase and manage
local server hardware or data
storage. The computing resources
are maintained and updated by Econolite. The web user interface provides an intuitive and easy-to-use means
to access Centracs SPM from any place, on any platform, at any time. Data collection is continuous and
unobtrusive to the rest of the transportation and traffic signal operations.
Centracs SPM is the next generation Econolite analytics, reporting, and data management platform. This
platform is designed based on FHWA ATSPM approach and Purdue University’s defined performance
measures using high resolution data to provide a platform for performance-based management for traffic
signal operations and maintenance.
Centracs SPM enables transportation agencies to make signal retiming strategy decisions based on high-
resolution dynamic traffic performance data without the costs associated with manually collected low-
resolution data and simulations. Centracs SPM provides continuous traffic data collection and analytics,
enabling transportation professionals to proactively optimize signal timing, enhancing mobility and safety. In
addition, Centracs SPM is an ideal fit for connected and autonomous vehicle and Smart Community
applications.
Centracs SPM provides the following features:
• Optimization: Optimizes all signals within a corridor to reduce the number of traffic stops and delays
based on the amount of time assigned to a phase (split), when the cycle starts (offset), or the length
of the cycle to serve all phases (cycle length). The optimization process uses Purdue University’s Link
Pivot and GOR/ROR (Green Occupancy Ratio/ Red Occupancy Ratio) to optimize arterial-level
parameters, including lead-lag sequencing.
• Web-Based User Interface: Provides an intuitive and powerful user experience while providing the
best and the latest features to all users.
• Overview Dashboard: Snapshot of the traffic system’s health by corridor, region, or agency.
• Heat Maps: Powerful visuals that overlays key performance metrics such as Arrivals on Green,
Vehicle Delays or Power Failures with a geographic context.
• Hot Spots: Identifies a list of intersections in a decreasing order of priority that requires remedial
action.
• Detector Concerns: Separately identifies a list of specific intersections with detector problems.

• Reports: Enhanced suite of analytical reports using performance metrics developed by Purdue
University.
• Metrics: MOEs categorized by Coordination, Transition and Preempt to drill down of key performance
indicators.
• Compare: Analyze before and after results to learn the effectiveness of remedial action.
We believe that Centracs SPM will provide the Town’s traffic engineers and operators with new levels of
capabilities for proactively optimizing traffic signal timing based on performance metrics.
Econolite has developed a new, ground-breaking approach to signal timing optimization based on recently
published academic and industry research initiated from the NCHRP-379a program that is also included with
Centracs SPM. This approach, Centracs SPM Optimization, has been validated by Transportation Research
Board participants, and is at the forefront of signal timing practice.
Under the NCHRP 3-79a research program, Purdue researched and developed a method for performance
measurement and signal optimization including a “Link-Pivot” optimization algorithm. Link Pivot is an
algorithm that works by stepping through possible coordination timing values at each intersection, while trying
to find the minimum delay or maximum arrivals on green. This effectively “pivots” across the possible
configurations on the approaches on the next link, providing optimized signal timing across a network of
signals. Those timing values achieving the optimal performance are retained.
Purdue has also developed a means for split optimization using the Green Occupancy Ratio (GOR) and Red
Occupancy Ratio (ROR) as the basis for split balancing. The research reveals GOR/ROR to be an accurate
measure for recurrent phase failure, and a basis for split rebalancing. GOR/ROR has become a better measure
of volume to capacity (V/C), since it has been designed to use occupancy detector data and does not require
counting detectors.
Econolite has implemented the results of this research, bringing to practice a means of GOR/ROR assessment
and split timing rebalancing. The SPM Optimization leverages Link-Pivot algorithms and Split Optimization
using GOR and ROR to run offline optimizations on Offsets, Cycle Lengths, Lead Lag Phase sequencing, and
Splits to generate optimized signal timing plans.
In order for SPM Optimization to automatically generate signal timing plans, it must group traffic flows into
time of day intervals and optimize the Cycle/Offset/Split (COS) values to meet the expected traffic flow for
each time of day (TOD) and day of week (DOW) interval. SPM Optimization identifies appropriate TOD groupings
for pattern optimization and allows user definition of the aggregation windows for these COS optimizations
Figure 10 - SPM Optimization

24
(i.e. use data from the last X weeks to facilitate plan changes on a Y weekly basis). It also allows threshold
windows to be set such that changes are only implemented when the measurable benefit exceeds a user-
defined threshold.
The Centracs SPM system also provides data analysis reports and other visual displays to facilitate user
understanding of these proposed changes. SPM allows both automatic and “user-approval-in-the-loop”-based
changes to the coordination plans stored within the system. This background plan update is a schedulable
algorithm within Centracs SPM that can be applied on a sectional basis. A historic log is generated that retains
all changes made to these coordination patterns.
The same Link-Pivot and ROR/GOR
methodologies that can be implemented as
background TOD plans within the system
can also be applied on a near-real time
basis. The cycle and offset selection
algorithms can be run in a recurrent fashion,
where the user establishes the frequency of
measurement, thresholds for change, and
sets up the system to perform near-real-
time optimization of the roadway network
(Figure 11).
The nature of coordinated operation requires that cycle and offset changes are made infrequently within the
system, so the penalty of recurrent coordinated transition does not outweigh the benefit of the new timing
modifications. Near real time is likely to allow five to fifteen-minute updates to the offset and cycle length
parameters, but can, in principle, be run as quickly as once per cycle length. This level of calculation is best
handled at a central system level and issued to the signals within a section. This helps to ensure cases of
detection failure and communications failure are handled with safe restoration to TOD operation.

Figure 12 - Optimization Recommendations
Proposal
Adaptive Signal Control and Advanced Traffic Management Systems

25
Split Optimization using the ROR/GOR approach can also be performed within the Cobalt controller, with no
need for centralized monitoring. This can be performed as modification to the base TOD pattern in effect, on
a cycle-by-cycle basis.
The combination of this real time cycle, offset and split optimization offers the Town a well-researched
optimization strategy quite unlike other adaptive systems, one that maintains proper signal optimization even
during periods of non-recurrent traffic demand.
5.1.3 Centracs Edaptive
Centracs Edaptive is the next-generation in adaptive
signal control, optimizing cycle, offset, and splits by
using high-fidelity 1/10th-second resolution data
available from modern ATCs. Data is the name of the
game. Better data yields better results, and with
Econolite’s Centracs SPM at its foundation, Centracs
Edaptive is making timing changes based on the best
possible data. Centracs Edaptive is web-based and offers deep analytical capabilities through Centracs SPM,
allowing users to quickly and easily ensure maximum performance of their signal control system.
Centracs Edaptive provides automated real-time signal adaptation and is a highly effective real-time adaptive
signal control solution that balances sustainability and reliability with the latest in adaptive algorithms. Target
applications include corridors with highly variable traffic patterns, changing weather conditions, special
events, high-priority corridors requiring maximum performance, and many others. Agencies can also make the
most out of existing detection. With advanced algorithms, stop bar detectors are used to drive split
optimization. Additional options exist for cycle optimization.
The system works by having controllers start off collecting high resolution data. The data is evaluated, and
several key calculations are run to determine the optimal values for adapting to changing traffic conditions.
Two to three cycles’ worth of data is needed for the algorithms to run. The new calculated values are then
communicated to the controllers through a proprietary object that facilitates changes to the internal timings
of the signal controller.
For optimizing offsets, a Link-Pivot algorithm is used. The algorithm works by stepping through possible offsets
between a pair of linked intersections. The arrivals on green are projected based upon the relative offset
times, allowing optimization of the impact that a change in offset at one intersection will have on the
downstream link. This optimization is then performed for the next roadway segments, effectively “pivoting”
Figure 13 - Optimization Results
Proposal
Adaptive Signal Control and Advanced Traffic Management Systems
for the Town-Wide Traffic Signal Upgrade Program
26
across the roadway network, optimizing each link between intersections. The offsets achieving the optimal
values are retained.
For cycle length optimization, the algorithm calculates the best cycle length to use, balancing the tradeoff
between capacity and delay.
The splits adjustments that are generated in Edaptive are the result of the system using Red Occupancy Ratio
(ROR) and Green Occupancy Ratio (GOR) to calculate the best combination of coordinated and side street
phase splits. The algorithm generates the best minimum splits to satisfy the non-coordinated phases and then
takes the extra time and applies it to the coordinated phases.
5.1.4 Controller Firmware and Hardware
The intelligence behind the signalized intersection is the traffic signal controller. Combined with the traffic
cabinet, the controller manages traffic flow and ensures safety for all roadway users. In the following section,
we describe both the proposed controller hardware and firmware, Econolite’s Cobalt Graphic ATC combined
with our EOS firmware.
5.1.4.1 Cobalt ATC
The Cobalt controller is the most advanced and innovative ATC on the market today. It not only fully meets the
ATC standards, but features a breakthrough hardened 7-inch Android-type touchscreen matched with a Linux-
based operating system. The Cobalt Touch application software package allows the touchscreen display to be
used for intuitive, graphical programming, making programming and access to functions the easiest in the
industry.
Cobalt ATC controllers may be configured with Econolite’s EOS controller software package or other pre-
qualified ATC/Linux software application software meeting current ATC standards. OS and software upgrades
can be made easily by USB memory stick, SD card, or Ethernet via Econolite’s Windows software installation
application. Cobalt includes a high-power, Linux-based Engine Board that is compliant with the ATC 5.2b and
proposed 6.10 standard for a NEMA standard TS2 Type-1 or Type-2.
In addition, all Cobalt controllers are designed to support Connected Vehicle (CV) applications including Signal
Phase & Timing (SPaT) messages. Combined with the Econolite Connected Vehicle Co-Processor, Cobalt
supports dedicated short-range communications (DSRC) protocol, providing the essential Vehicle-to-
Infrastructure (V2I) interface between the controller and DSRC-based roadside equipment (RSE). Cobalt can
facilitate the continuous collection, aggregation, and use of real-time traffic data that is requisite for the CV
and Smart Cities environment. Cobalt opens the door to new levels of smart intersection and traffic control
and positions a transportation agency or metropolitan planning organization with the fundamental V2I
capabilities in support of the Connected Vehicle future. Cobalt ATC controllers are also capable of collecting

Adaptive Signal Control and Advanced Traffic Management Systems
for the Town-Wide Traffic Signal Upgrade Program
27
and storing the high-resolution data needed in support of the Purdue Coordination Diagrams (i.e., individual
detector information at a 100ms resolution (10 times per second)).
5.1.4.2 EOS
We are proposing to use Econolite’s EOS, the next-generation
traffic controller firmware/software developed for the Cobalt and
other properly configured ATC controllers. EOS features improved
usability with a redesigned user interface and traffic control
algorithms. EOS was founded upon the rich set of NTCIP 1202
and Econolite proprietary traffic control features, and provides an
expansion of traffic control capabilities, while focusing upon
simplicity and ease-of-use. This software provides a timely preparation for the forthcoming demands of
Connected Vehicle traffic control systems.
Econolite EOS’ user interface has been designed to maximize usability of traditional displays, as well as
incorporating a new web user interface that includes a virtual suitcase tester. EOS can be accessed via a
network interface, which can be local or remote, wired or wireless, and allows monitoring or programming of
the controller through any web-enabled device, including smart phone, tablet, laptop, or desktop computer.
EOS’ new leading-edge features and enhancements also include:
• User Security login for field access management
• Android phone and mobile device support
• Key navigation across the UI for touch-less management
• Key shortcut (SpFn + Main) to switch to classic UI
• Quicker navigation and faster loading of content
• Robust architecture
• Support for all cabinet types
EOS has improved real-time decision-making, allowing dynamic changes to nearly all features and timing ‘on-
the-fly.’ EOS supports the configuration of phase and overlap timing in predefined tables that can be swapped
to meet immediate needs. Dynamic-sequencing is achieved by updating prior phase-next selections at the end
of a red clearance and even allows phase-sequence swaps in the middle of active phase timing.
EOS features a brand-new coordinator design, enabling immediate coordination decisions rather than awaiting
a cycle endpoint. This coordinator includes adaptive split balancing using the Purdue GOR/ROR5 metric for
phase failure. This coordinator goes a step further by supporting localized adaptive splits. Adaptive splits
perform a split re-allocation, balancing splits per the newly published GOR/ROR5 metric. This feature brings
many of the operational benefits of adaptive control, without the need for a separate adaptive control system.
EOS’ improvements to the core traffic controller operation, enhanced features, and improved usability, helps

5.2 Detailed Scope of Services
The ESI Team is proposing the following Work Plan to deploy an ATMS and ATCS for the Town of Los Gatos.
Proposal
Adaptive Signal Control and Advanced Traffic Management Systems
for the Town-Wide Traffic Signal Upgrade Program
28
5.2.1 Task 1 - Project Management
Project management is a critical part of the deployment of any technology project. To emphasize its
importance, we propose a dedicated project management task to ensure that the ESI Team and the Town
share common goals and expectations of the project, manage changes needed through the course of the
project, and execute the project to meet those goals and expectations. The ESI Team will perform proactive
project management throughout the course of the project and provide periodic invoices and progress reports
to summarize the project status.
We are proposing a highly experienced Project Manager for this project, Mr. Marc Miranda. Mr. Miranda’s
qualifications are detailed in Section 4.3 of our proposal.
A key to The ESI Team’s Project Management approach is to develop a Project Plan as detailed below.
Project Plan
The Project Plan will document the following elements:
• Project Scope – This document and any modifications that may be required over the term of the
contract.
• Major Deliverables – This document and any modifications that may be required over the term of the
contract.
• Risk Assessment – Identifies major risk elements and mitigation actions.
• Resource Requirements – Includes team organization and responsibilities of stakeholders.
• Project Schedule – Gantt chart periodically updated to reflect project progress.
Bi-Weekly Progress Meetings
The ESI Team will establish bi-weekly project meetings via teleconference to keep the Town informed of project
progress and upcoming activities. These meetings are structured as “status only” and are intended to last not
more than 30-minutes. This time frame ensures regular stakeholder attendance and insists that more in-depth
discussion to be taken offline. The agenda for these meetings will form two purposes: to guide the discussion
and function as a Status Report. These meetings will be limited to the following discussion points:
• Estimates of progress
• Work performed during the prior period
• Work anticipated for the current/following period
• Any deviations from the project plan along with their current issues, status, and how they are to be
remedied.
For each bi-weekly progress meeting, the ESI Team will provide the meeting agenda and notes. The notes will
include a “rolling” Action Item list that identifies and summarizes the Action Item (what needs to be done),
Responsible Parties (who needs to do it), Resolution Dates (when will it get done), and End Result (how was it
accomplished).
Weekly scheduled discussions between the Econolite and Town project managers with be held to work through
any schedule or task needs and to keep each informed of any changes or modifications that may be needed.
Invoices
Invoices will be submitted in accordance with the contracted milestone payments.
Assumptions:
• The ESI Team will participate in the bi-weekly progress meetings either in person or via
teleconference.

5.2.2 Task 2 – Advise on ATMS and ATCS System Controller and Detection
Requirements
The two factors with the largest impact of the effectiveness of an ATCS (and ATMS) are adequate detection
and reliable communications. As part of Task 2, the ESI Team will provide a thorough review of all existing
detection, controllers and communications. We recognize that the Town does not necessarily have as-builts
for all intersections. We intend to overcome this challenge by conducting a full field review to document and
evaluate the extent of video detection coverage, and adequacy of this coverage relative to ATCS operation at
all ATCS intersections. The field review, in conjunction with a review of existing as-builts will also look at needs
and requirements for controller and communications upgrades.
The performance of the ATCS relies upon the accurate mapping of field detector channels to the correct
detector assignments within the system. One deployment risk resides with the potential inaccurate mapping
of existing detection channels. As understood from the RFP, the Town will be closing any detection shortfalls
and installing any necessary additional detection system elements under separate contracts. The ESI Team
will coordinate with the Town on detection requirements to that ensure accurate locations and channel
mapping have been appropriately addressed.
For those intersections with existing, adequate detection, verification of the detector layout will be required as
part of the field review.
Because Centracs Edaptive works with high-resolution controller data, it is compatible with all detection
systems used in signal actuation, utilizing data from controllers. Ideal detectorization for adaptive operation
and performance metrics should include:
• Stop bar, lane-by-lane on each phase
• Main street advance or midblock (arrival profiles)
• Side street advance for cycle adjustment on busy side streets
We understand that the Town will be responsible for design plans and procurement relative to any detection
upgrades. The ESI Team will work closely with the Town during this activity to ensure design elements are
consistent with the needs and requirements of our proposed ATMS/ATCS solution.
Assumptions:
• Town to supply all available as-builts.
• Town to provide access to all controllers for field inventory by ESI Team.
5.2.3 Task 3 - Furnish ATMS and ATCS Software and Hardware
As part of this task, the ESI Team will provide Centracs ATMS and Edaptive software, ATMS hardware,
controllers and communications equipment for the project.
ATMS Software and Hardware
Econolite will supply a database/core server as specified in Table 2 to host the Town’s ATMS. In addition, we
will provide the Town with licensing for the Centracs ATMS and Edaptive.

Assumptions:
• Town will provide an equipment rack and rack ancillaries, power, and network connections for the
server described in Table 2.
• Town will provide all TMC networking/communications equipment and VPN software.
• Town will provide the ESI Team with remote access to the server.
5.2.4 Task 4 - Installation, Integration, and Deployment
The ESI Team will work closely with Town staff to define a methodology for deploying the Town’s ATMS in a
cooperative manner. This will include procedures for setup of the server and configuration of central and
mobile workstations. The ESI Team will first baseline the existing system and work with Town staff to further
refine our understanding of project requirements as well as relevant Town IT Department constraints.

ATMS Setup
Central System – Setup
The ESI Team will provide a Centracs license for 50 intersections. Centracs will be installed on the server
supplied by Econolite in Task 3. Prior to installation on the production server environment, the ESI Team will
setup and configure the Centracs ATMS with all system parameters on a staging server maintained in
Econolite’s Anaheim office.
Intersection Graphics
We will develop a typical graphic representation of an intersection and submit a template to the Town for
review and approval. The template will include icons for:
• Intersection status (1st level)
• Intersection status with plan (2nd level)
• Intersection status with main street green (3rd level)
• Intersection phase movement display with status (4th level)
Upon agreement as to exactly how the Town wants an intersection to look and what graphical elements are
important to you, we will use this template to reproduce graphics for thirty-one (31) intersections and provide
the Town with training so they are able to develop graphics for, and integrate any future intersections.
Intersection Properties
Each intersection will be geo-located and intersection properties, including intersection name, main street,
cross street, IP address or serial communications parameters (as applicable), will be configured.
Central System – Installation
The ESI Team will install, configure, and integrate the Centracs ATMS on the server supplied by Econolite. We
are assuming the Town IT Department will assist the ESI Team with establishing a connection to the Town
network switch for access to the field network, the Internet, and any workstations (local or remote) that require
access to the Centracs system. In addition, the ESI Team will work with Town IT staff to identify network routes
to the field network and create provisions for remote access for maintenance and software updates.
Client Software
Econolite will install and configure the Centracs client software application on three (3) Econolite-supplied
workstations and/or laptops. There is no limit on the number of workstations and no cost or licensing required
to add additional workstations to the system.
ATCS Setup
The ESI Team will set up the Los Gatos Boulevard corridor’s cloud-based Centracs Edaptive site and configure
and integrate all thirteen (13) intersections to provide high-resolution data to Centracs Edaptive. The following
steps will be required for the successful deployment and operation of the system.
• Acquire as-built detector layouts from the Town (Task 2).
• Review existing intersection and detector layouts, taking notes on what detector is assigned to what
input in the controller, the location of the detector on the street, and what function the detector is
serving (e.g., stop bar, advance, departure, left turn).
• Site setup & configuration.
• Configure Intersection Data Maps (IDMs) for each intersection based on detection and controller
configuration information.
Phase assignments and detector assignments are mandatory.

Speed limits are required. It is also useful to have volume estimates to better establish a
saturation flow rate value that is more accurate and localized than the standard 1800-
1900 vehicles per hour per lane (vphpl).
Perform Quality Assurance/Quality Control on all IDMs.
• Setup corridors in SPM, including grouping and defining corridors and operational parameters in
consultation with the Los Gatos Project Manager.
• Run SPM for two weeks to ensure SPM graph data is valid. Review data and modify settings as
necessary.
• Run SPM Optimization for two or three 2-3-week intervals. Push the “best” Optimization result to the
field to update base signal timings.
• Once SPM has gathered sufficient historical operations data, the system is ready to begin Edaptive
testing:
This should be accomplished in steps for both the system to “learn” the corridor as well
as for agency staff to understand how Edaptive will begin modifying signal timing to
improve overall operations. Step 1 will be to operate Edaptive for 1-3 days for 1-hour at
a time, Step 2 will then increase operations for 1-3 days of 4 hours at a time, Step 3 will
then move to operating Edaptive for one week of 8 hours per day. Once the initial three
steps are complete, the system will be ready to move to full control per Town desires.
We recommend that Town and Econolite field technicians be on-site in the field to verify
street conditions are acceptable (no out-of-control congestion, or other non-regular
conditions) during initial Edaptive testing.
Continue to monitor Edaptive remotely from our Colorado Springs office.
• Once the initial testing is complete, Econolite proposes to also conduct a simple before/after study.
This include the gathering of SPM data in weeks prior to SPM Optimization change versus weeks
running full Edaptive to verify operations have improved and to quantify the overall improvement and
operations benefit to the Los Gatos Boulevard corridor.
Controller Migration
The ESI Team will apply a thoughtful and consistent process in performing the controller database conversions
and bench testing necessary to migrate to the Cobalt ATCs. The following steps outline the process we will
employ:
1. Data Collection: The ESI Team will obtain the most current and up to date timing sheets and
phase diagrams for each intersection from the Town. Where possible, we will upload controller
databases directly from the Town’s Aries system.
2. Database Conversion: To facilitate the conversion process, the ESI Team will provide specialized
training to our team of engineers to make absolutely certain that even the most obscure
database elements are properly managed in the conversion process. Minimum clearance
intervals and safety parameters will also be assessed during the conversion process and
recommendations will be made, as necessary, to make improvements. While paper records will
be produced, timings will be electronically input into a virtual controller and uploaded to a
Centracs staging server to facilitate loading the timings into the controller.
3. Loading: A controller will be connected to the Centracs staging server. The converted database
will be downloaded onto the controller. The controller will then be labeled, removed, and staged
for testing and eventual deployment.
4. Testing and Quality Control: The converted timing database will be downloaded to a test
controller to verify proper conversion and acceptance in the controller environment. Engineers
will validate that the databases have been properly converted prior to making a recommendation
for field deployment. TJKM will provide oversite and quality control of this step to ensure
controllers are field-ready before deployment.
Proposal
Adaptive Signal Control and Advanced Traffic Management Systems
for the Town-Wide Traffic Signal Upgrade Program
34
5. Field Installation: After testing and quality control is complete, the ESI Team will take the
controller to the field and install it into the cabinet. We will develop and document procedural
steps to make certain the intersection is operating properly including detector programming and
“walking-the-intersection,” to ensure the intersection phasing is per plan.
Ethernet Device Configuration
We understand Ethernet devices supplied by the ESI Team under this project will be installed by the Town’s
Electrical Contractor. This Contractor will be retained by the Town for installation services in support of the
field design (Ethernet devices, fiber optic branch cables, controller cabinet change-outs) prepared by the
Town’s Field Design Consultant. In support of these activities, the ESI Team will be responsible for
programming all field Ethernet equipment based on IP addresses and VLAN information provided by the Field
Design Consultant. The Town’s Electrical Contractor will then install this equipment and the ESI Team will
coordinate with the contactor to confirm end-to-end communications from each field Ethernet device back to
the Town’s TMC.
Assumptions:
• Town will provide current phase diagrams and timing/coordination sheets for thirty-one (31)
intersections.
• Any required e-mail services will be provided through the Town’s SMTP relay server.
• All software installations will be coordinated through the Town’s IT Department.
• Remote access to the server can be arranged through the Town’s IT Department.
• Town will provide end-to-end Ethernet communications between the Centracs server software and
the traffic signal controllers at each project intersection.
• Town will establish a connection to the Town network switch for access to the field network, the
Internet, and any workstations (local or remote) that require access to the Centracs system.
• Town IT Department will provide the necessary power and time sources.
• The Town will contract with a separate contractor to install the Ethernet communications equipment
in the field, as well as any additional intersection detection as advised by the ESI Team in Task 2.
• The Town/Town’s Field Design Consultant will provide IP addresses/VLAN information for all
Ethernet devices.
5.2.5 Task 5 - System Testing and Acceptance
Acceptance Testing
Once all controllers are brought online, the System Acceptance Test will be conducted in accordance with the
Acceptance Test Procedures (“Test Plan”). The Test Plan will be based on Econolite’s existing Standard
Centracs Test Procedures modified to incorporate the Town’s requirements contained in the RFP (connectivity,
data exchange, load, and functionality tests). The Test Plan will include details on test setup, test scripts, test
oversight and witnessing, test reports, pass/fail criteria, and test dependencies.
The ESI Team will provide a Draft Test Plan to the Town for approval 30-days before the acceptance test is to
begin. The Town shall review the Draft Test Plan and provide review comments within 14-days. The Test Plan
will not be final until accepted by the Town.
This initial phase of testing includes a step-by-step walk-through of every procedure documented in the Test
Plan. This phase of testing ensures that the Standard Centracs Test Procedures and the specific additional
functional and performance requirements of the Town are observed and proven to successfully function.
Proposal
Adaptive Signal Control and Advanced Traffic Management Systems
for the Town-Wide Traffic Signal Upgrade Program
35
If, during performance of the System Acceptance Test, an item is marked as “failed,” the ESI Team and Town
staff will agree to a course of action.
This test is incredibly thorough and painstakingly detailed. The ESI Team will conduct, document, and record
all test results. The Town’s Project Manager (or their designee) will witness all tests and sign-off on each
procedure as it is completed. At the conclusion of the System Test, the ESI Team will prepare a test report
summarizing the results of the test, documenting any areas of the test that need to be corrected. As necessary,
the ESI Team will resolve any issues that were identified during the System Test, demonstrate the proper
operation to Town personnel, and document the corrections.
Burn-in and Acceptance
Upon successful completion of the System Acceptance Test, as well as 30-days of error free operation during
the subsequent burn-in period, the Town will grant “System Acceptance” and the Warranty period will
commence.
Assumptions:
• System Acceptance Test will be conducted after the system has been installed and all intersections
brought online.
• Town will review the Draft Test Plan & provide review comments within 14-days.
• System Acceptance Test will be performed over a 1-day period and the Town’s designated
representative will be available to witness/participate.
5.2.6 Task 6 - Training and Documentation
Training
The ESI Team will provide all training necessary for the Town to successfully operate and manage the ATMS,
ATCS, and traffic controllers. Our proposed system training will be detailed in a Training Plan that identifies
the lesson plan for each course, along with the literature, standard operating procedures, manuals, and test
materials that will be used. The training plan will describe the ESI Team’s role and responsibilities for each
course and will include a training schedule listing each period of instruction and the time required for each
period. The ESI Team will submit the Training Plan to the Town for review and approval 30-days prior to the
scheduled start of any training.
The ESI Team will provide a minimum of 84-hours of training as detailed in the following table:
Training Session Expected Duration
1. System Operations 8-hours

The ESI Team will provide all training materials, and each training will be designed for up to ten (10) people.
This training will include both classroom-style instruction on system functionality and use as well as “hands-
on” training and will be suitable for both traffic systems engineers and traffic signal technician staff. We
understand that some areas may require more in-depth training than others and will adjust the curriculum
according to the Town’s needs. Training will be conducted at Town facilities with access to the system for
optimal understanding of the system.
System Operations Training will address each of the following topics:
• System Overview
• System Set-Up, Configuration, & Calibration
• Graphics Set-Up
• Basic Operations
• Advanced Operations
• Reports & Alarms Generation
• System Maintenance
• Troubleshooting
System Administration and System Maintenance Training will be focused toward IT Staff that will administer
the system and be provided as follows. This content can be adjusted to best meet the Town’s needs.
• Introduction and Overview - This session will review the System Hardware, System Software,
Centracs capabilities and features, and a brief tour of the Traffic Management System Workspace.
The discussion will also include how to log-on to Windows for both remote connections and local
workstations, launching the Client application, logging on to Centracs, accessing system graphics,
and an explanation of the workspace components.
• Windows Security - This session will provide a general overview of the Windows security system, as
well as creating and removing user accounts. Each attendee will have the opportunity to add or
remove a user account to/from the system.
• Windows Event Logs - This session will cover both the System and Application Event Logs within
Windows. Specific items appearing within the logs will be discussed and their relationship to system
performance will be reviewed.
• Database Backups - This session will review how the system backs-up the SQL Databases and the
required operator actions.
• Software Installation Procedures - This session will review the procedures used to install the
Centracs ATMS software on a target computer. Additionally, general setup requirements for each
“type” of computer will be reviewed.
• The Centracs Server Suite - This session will review the function of each component comprising the
server software suite and will cover the Administration menu items associated with the Client
application. Adding and deleting users to/from the Centracs system and assigning user privileges will
also be reviewed.
Intersection Maintenance Training will focus on controller programming, maintenance, and troubleshooting
with an emphasis toward how the controller works in conjunction with the ATMS and ATCS.
In addition to formal, on-site training, we are also able to provide at no cost to the Town on-demand training
via the Econolite Learning Center (http://learn.econolite.com/).
Documentation
The ESI Team will provide the Town with a complete systems documentation package that includes the
following:
Proposal
Adaptive Signal Control and Advanced Traffic Management Systems

37
• Software submittals
• System architecture diagram
• User/operator manuals
• Software programming manuals & procedures
The documentation package will address all software and hardware provided under this contract and will be
subject to review and approval by the Town before final system acceptance. The ESI Team will submit all
documentation for review and approval by the Town.
Assumptions:
• Trainings will be conducted at a Town facility with real-time access to the installed system.
• Town personnel will be available to participate in the training(s).
5.2.7 Task 7 – System License, Warranty, and Support
Licensing
The ESI Team is providing a perpetual 50-intersection Centracs ATMS license and the third-party software
necessary to run the ATMS, as detailed under Task 3 of our scope of work and subject to the terms and
conditions of the Centracs Software License Agreement contained in the Appendix.
The Centracs Edaptive ATCS is being licensed for 13-intersections for a period of three (3) years from system
acceptance and is subject to the Cloud Services Agreement contained in the Appendix.
Centracs – Warranty & Support Terms
Econolite will provide a standard 1-year warranty following successful completion of the System Acceptance
Test. The warranty covers all defects and bugs in the central system software and entitles the Town to free
software updates. Third party hardware and software warranties will be transferred to the Town.
In addition, we provide unlimited remote technical support via phone and Internet and, of course, our local
support team is nearby to answer any questions, solve virtually any problem, and provide assistance to help
the Town get the most productivity out of its new Centracs system.
Regular support is available during normal business hours, from 8am to 5pm Mountain Time. For emergencies,
Econolite also has a toll-free 24x7 maintenance hotline that can log trouble tickets and generate appropriate
responses after hours.
For issues requiring a deeper level of technical support, Econolite has a dedicated staff of maintenance
professionals and support group to supplement the local team. These professionals together make a team
unmatched in the industry, dedicated exclusively to supporting deployed Centracs systems. Our Centracs
system support engineers provide a managed process that responds quickly to any customer questions and
problems as they arise.
To facilitate access by these individuals, we propose utilizing a VPN connection to remotely access the system
and assist in diagnostics and troubleshooting. This is a very effective approach that enhances efficiency and
reduces Town staff time for troubleshooting. In addition, software updates can also be loaded remotely
through this connection. We will work with the Town’s IT group to establish access which is compatible with
the Town’s IT policy.
In addition to the 1-year Warranty, our proposal includes two years of additional coverage under our Premier
Software Maintenance Agreement (SMA). A sample of this agreement has been included in the Appendix of
our proposal. During the warranty and subsequent support period, Econolite will provide the following support
services:
Proposal
Adaptive Signal Control and Advanced Traffic Management Systems
for the Town-Wide Traffic Signal Upgrade Program
38
• Technical Support – Assist Town staff with routine questions about the use, configuration,
management, and troubleshooting of Centracs.
• Software Upgrades – Econolite will provide all released upgrades to the Town. Software upgrades
include those to address errors, defects, security flaws, etc. and those that provide enhancements,
new features, new functions, etc. Centracs will retain all system, user configuration, and preferences
when applying software upgrades. If requested by the Town, Econolite will provide technical support
to install software upgrades.
So long as the system is under warranty or SMA, all Centracs updates are available at no additional charge.
New feature releases are also included in the support and we typically release one upgrade per year, further
assuring the Town will remain on the leading edge of technology well into the future.
Throughout the Warranty and subsequent SMA periods, the ESI Team will provide bi‐weekly review and
reporting, confirming all system components are properly functioning, including verification of two‐way
communications, system software and hardware, local controller, and detection health. In the event of any
system-related problems, we will prepare a list of action items to address any deficiencies or failures.
Assumptions:
• Per the resultant contract, the Town does not perform any acts that void the Warranty.
• The Town will provide VPN access that allows Econolite to remote into Centracs so that we can
provide support, warranty, and maintenance services from our Colorado Springs Technical Center.

5.4 Cost Controls & Budgeting
Econolite’s approach to cost control and budgeting for all of our projects involves the following four processes:
1. Plan Cost Management
2. Estimate Costs
3. Determine Budget
4. Control Costs
We describe each of these processes in the following sections.
5.4.1 Plan Cost Management
Plan cost management is the initial process of project cost management where we define how the costs of
the project are estimated, budgeted, managed, monitored, and controlled. We typically use WBS (Work
Breakdown Structures) or historical data for similar projects to define the cost resource requirements, which
include time, material, labor, equipment, etc. This process gives a rough outline of the number of resources
involved and shows the optimum path to manage the project costs throughout the project lifecycle.
5.4.2 Estimate Costs
The second step in our project cost management planning helps in estimating the cost of the resources
required for project completion. Since cost is an important variable that ensures project success, we are very
careful while producing the estimated amount of the total project cost. Throughout the project lifecycle, this
process is performed at periodical intervals. Our Project Manager uses various methods to estimate costs
depending on the amount of information available.
5.4.3 Determine Budget
Determining the budget is the third step in our cost management process where the estimated cost of
individual activities or tasks is summed up to draw the cost baseline. The cost baseline of the budget includes
all the authorized funds that are essential for project execution. This budget includes various reserves of
contingency while keeping the management reserves far at the bay. Cost baseline is an authorized time-
phased budget that is used as the initial point for monitoring and calculating the project performance and
progress. This process is executed at specific points in a project which are generally predefined.
5.4.4 Control Costs
Controlling costs is the final step in our project cost management process, on that is primarily concerned with
the measurement of variances of the actual costs from the proposed baseline. Various methods and
procedures are implemented here to track the project performance and expenses against its progress rate.
Meanwhile, all these variances are recorded and compared with the actual cost baseline. The control costs
process is responsible for explaining the reason for a variance and further assists our Project Manager in
taking corrective actions to incur minimal costs and control the entire project’s expenses to close it within the
agreed budget.

5.5 Additional Information
5.5.1 Systems Engineering Issues
Econolite recognizes the importance of the Systems Engineering approach (Figure 14) to the development and
deployment of complex traffic management systems, and the deployment of an ATCS and ATMS for Los Gatos
is no exception to this process. Upon commencing the project via kickoff meeting, as part of Task 2, we will
conduct a thorough review of the Town’s final Concept of Operations, working closely with all project
stakeholders to ensure all critical system engineering issues are identified and addressed prior to system
deployment. Based upon the results of this review, system requirements will be, as necessary, refined to
ensure the final deployed system is consistent with the initial concept for the Town.
5.5.2 Minimizing Cost & Schedule
As previously mentioned, our Centracs Edaptive ATCS solution provides adaptive control capabilities based on
system performance measures derived from Centracs SPM. While we recognize that the Town intends to
procure an Automated Traffic Signal Performance Measures (ATSPM) system through a subsequent RFP later
in 2020, as a value-added proposition, we are proposing to include SPM features as part of our proposed
ATCS solution for this project at no additional cost to the Town. This will enable the Town to begin realizing the
operational efficiencies of ATSPM at a much earlier date than it would otherwise be able to achieve.
An additional cost and schedule saving measure involves the Town’s ability to continue using compatible
Econolite controllers with the new ATMS and ATCS. Econolite ASC/3 controllers are Ethernet and NTICP
capable, and fully functional under the ATMS and ATCS solution we are proposing. Intersections equipped with
these controllers (11 of the 31 controllers identified in the traffic signal system inventory) will not require an
immediate controller upgrade. Similarly, the Town has recently purchased several Cobalt ATC controllers that
will not need to be replaced under the proposed system.

5.5.3 User Groups and On-Going Support
User Groups
Historically, Econolite has been a strong supporter of hosting User Groups for our Centracs (and other
product) customers, as we recognize the value of these groups both to our customers, and also to Econolite
as we continue to improve, grow, and evolve our product offerings. Our customers benefit from gaining
insight from other Centracs users, as well as Econolite’s technical experts Similarly, the feedback we receive
from our users is invaluable in aligning our product’s capabilities with our customer’s needs.
Typically, our User Groups bring together product users and product experts who meet on an as-needed
basis to discuss user experiences, share tips and techniques, and provide product recommendations for
future product development. These User Groups are comprised of member agencies that change based on
the Econolite product of topic (systems, specific system modules, sensors, controllers, cabinets, etc.) and
consist of anywhere between 2 – 10 identified agencies.
Econolite’s User Groups have taken a number of different forms, from webinar-based, product-expert-lead
discussions, to virtual trainings, user-voice online forums, fact-to-face meetings at our Anaheim
headquarters, product showcase events, Client Advisory Councils, and at user-premises scheduled meetings.
The frequency of these Groups is really based on the agency’s needs, project status, and user/facilitator
availability. A typical agenda might include:
1.Introductions
2.Product Overview
3.Demonstrations
4.Lightning Talks (4-5-minute talks from each user on their current experience)
5.Tips & Techniques
Econolite has never charged participation fees for our User Groups and has no plans to do so in the future.
On-Going Support
Please refer to Task 7 of our Scope of Work for a detailed description of the on-going support we are proposing
following final system acceptance.
