1. Purpose of Document
This document presents the Systems Engineering Management Plan (SEMP), developed to guide the planning, design, procurement, and deployment processes of the Contra Costa County Transportation Authority’s (CCTA’s) Safety and Mobility of Arterial (Smart) Signals project. The Smart Signals project will develop, manage, and implement Intelligent Transportation Services (ITS) initiatives that will improve multimodal mobility, maximize highway and major arterial system throughput, reduce environmental impact, and improve operational efficiency and safety throughout the Contra Costa County. This project also serves as a transit signal priority, emergency vehicle preemption, and data communication infrastructure solution for the signal systems. This project lays a foundation for Smart Cities initiatives which connect Intelligent Transportation Services to other Smart City Systems on a countywide basis.
This document explains the Systems Engineering Process intended for the project. A Systems Engineering process is an iterative process used throughout the life cycle of a project.
Since this SEMP is developed early in the lifecycle of the project, several versions might be released during the life of the project. This version of the SEMP is based on the work that is completed for the Project listed below:
• Defined Vision, Goals and Objectives
• Meetings with each of the 20 jurisdictions in Contra Costa County (19 cities/towns and unincorporated County) and transit agencies
• Needs Assessment
• Identification and Evaluation of signal infrastructure • Identified solutions and concepts
• Created probable cost estimates for each agency
• Identified project benefits
• Identified base package
• Support design, procurement, implementation, operation & maintenance

2. Scope of Project
PROJECT OVERVIEW
Contra Costa County is home to 19 cities/towns and numerous unincorporated communities.
There are approximately 1400 traffic signals within the County, Caltrans-owns and various city-owned. Most of these traffic signals are located either along major arterials, including State Routes, identified as Routes of Regional Significance (RSS) or other major and minor arterials in the cities/towns.
The existing traffic signal systems in most jurisdictions located within Contra Costa County are legacy systems and are outdated or antiquated compared to newer traffic signal systems.
These signal systems currently lack the communication infrastructure such as fiber and cellular/wireless-based communication, which makes it difficult to implement traffic signal synchronization and coordination between traffic signals along an arterial. Most corridors do not currently include Signal Control and Prioritization (SCP) technologies to promote transit usage to reduce delay and travel times for transit vehicles and reduce response time for emergency vehicles.
These deficiencies result in severe traffic congestion within the cities/towns and may result in spillover onto freeways and cause a chain reaction of congestion along local arterials. The current system contributes to overall commuter travel times and delays, increases
CCTA Smart Signals Systems Engineering Management Plan-Draft | Page 3 greenhouse gas emissions and fuel consumption, as well as incidents and collisions. These deficiencies were documented following extensive discussions with the cities and towns regarding traffic signal operation within the Contra Costa County.
CCTA and the project Stakeholders have initially identified these deficiencies, which are translated as the following project goals.
► Improve safety and minimize crashes, injuries, and fatalities between motorists, bicyclists, and pedestrians.
► Optimize mobility along major corridors and RSS.
► Advance to Smart City and Internet of Things (IOT) solutions.
SOLUTION
The Smart Signals project will develop, manage, and implement ITS initiatives that improve the safety and efficiency of multimodal mobility, maximize highway and arterial system throughput, and improve operational efficiency, safety, and reduce environmental impact throughout the county. By upgrading the existing legacy systems and providing interconnectivity throughout Contra Costa County signal systems, the county’s traffic signal systems can be prepared for future emerging technologies including connected and/or autonomous vehicles, big data, integrated corridor management (ICM), enable implementation of incident management strategies and Smart Cities initiatives. This solution can enhance the sharing of real-time information between agencies and the public using existing and next generation ITS technologies.
The upgraded traffic signal systems and signal interconnect will help smooth traffic flow and ease recurring traffic congestion by expanding mode choice options and reducing travel time on local streets and roads. Upgraded traffic signals will benefit pedestrians and transit commuters by reducing wait times at intersections, improving total travel time for all modes while making transit and pedestrian more viable transportation options. The Smart Signal systems would also improve the safety of the pedestrians, bicyclists, vulnerable road users, and people with disabilities by deployment of detection systems.
To accomplish these goals, CCTA is applying a Smart Signal approach that will include the implementation of ITS equipment including upgraded traffic signal controllers and cabinets, upgraded Advanced Traffic Management System (ATMS) for each agency to provide remote command and control from a centralized Traffic Management Center (TMC) or Traffic Operations Center (TOC) location, Closed-circuit Television (CCTV) cameras, SCP for transit and emergency vehicles, and vehicle detection systems deployed on predefined designated arterials and state routes. These improvements will provide local cities and Caltrans day-to- day county-wide traffic management capabilities in addressing recurrent traffic congestion as well as provide CCTA capabilities for managing the system during non-recurring traffic
CCTA Smart Signals Systems Engineering Management Plan-Draft | Page 4 congestion caused by diverted traffic due to major incidents on the freeway or during any evacuation efforts.
The Smart Signals project’s key features and benefits include:
► Providing infrastructure for a countywide traffic management system ► Upgrading local signal controllers and signal system hardware, software, and firmware ► Deploying bicycle and pedestrian detection software for vulnerable road user protection ► Providing SCP, including Transit Signal Priority (TSP) and Emergency Vehicle Preemption (EVP) capabilities
► Enabling local event management signal timing options ► Taking a proactive approach to safety by identifying “near miss” situations for analysis ► Enabling cities and CCTA to proactively manage day-to-day traffic ► Enabling cities to proactively manage traffic on local streets that has diverted off the freeway due to a major freeway incident
► Identifying alternative routes with timing optimized for incident management ► Allowing shared control and operation, improving cross jurisdictional traffic management
► Allowing cities/CCTA access to monitor all CCTV cameras and traffic signals for the purpose of optimizing day-to-day operations
Deployment of the Smart Signals Project is expected to result in operational and safety improvements for all modes of transportation, such as:
► Decrease in travel time,
► Decrease in total delay,
► Reduction in number of stops
► Reduction in secondary accidents
► Decrease in fuel consumption and greenhouse gas emissions ► Promotion of transit ridership
► Reduction of response time for emergency vehicles
When operating together, these enhancements increase safety and reliability, and support environmental sustainability, economic development, and equitable access for all travelers.

This document contains all the test requirements and procedures, who is responsible for testing, and the internal integration testing schedule for each set of integration use case scenarios.
CHANGE CONTROL
A Change Control Board (PMT, PLT) will establish baseline templates and/or reports for each of our project deliverables. A baseline template is an approved configuration that can be changed only through formal change control procedures. Configurations serve as references for further activities. An ‘approved’ status for a configuration means that all items composing the configuration are final. IBM’s Engineering Lifecycle Management (ELM) and e-Builder tools will be used to manage the deliverables of these six baseline subcomponents:
• Requirements Baseline: For requirements documentation and management activities; • Functional Baseline: For system and interface specifications and architectural descriptions;
• Design Baseline: For solution design containing hardware, software, data, and tools components;
• Documentation Baseline: For project documents (e.g., plans, safety, estimates); • Test History: To trace integration, verification, validation, and test activities (e.g., procedures, reports); and
• Modification History: For reports generated from the change management tool to trace accepted change requests considered in the project baseline. • All changes to baselines, such as change orders, will be submitted and approved in e- Builder. E-Builder is the program management tool used by CCTA which augments the document control process by implementing pre-built workflows for all approval and submittal processes. Initially, the systems engineer or integrator puts the baseline documents on e-builder. If a change request is made, the Change Control Board (PMT and PLT) will evaluate the change request and involve the Project Technical Team if needed, then decide on approval of the change request. The Systems Integrator will then implement the approved change. E-Builder’s role in change control is shown in the Change Control Diagram in Figure 1.

4. Systems Engineering Process
The CCTA Project team will utilize a Systems Engineering Process to outline the process in which to develop and closely adhere to a design process that is acceptable to CCTA and the project
CCTA Smart Signals Systems Engineering Management Plan-Draft | Page 10 stakeholders. CCTA will utilize the services of consultants and input from stakeholders to confirm that this process is followed.
A Systems Engineering process is an iterative approach to technical management, procurement, system design, product realization, and technical evaluation at each level of the system, beginning at the top and propagating those processes through a series of steps that eventually lead to a preferred system solution, and then continue through detailed design, deployment, integration, verification, and initial operations.
The Systems Engineering process for the Project will follow the V-Model as defined in the FHWA Systems Engineering for Intelligent Transportation Systems Guide and illustrated in Figure 2.

5. Transitioning Critical Technologies
Critical technologies are those technologies which prevent the system from meeting its goals/objectives and providing the functionality required. There are no backups to critical technologies needed for the “solution” described in the previous sections. With this definition, all technologies in the proposed system are critical. The technologies that will be used in this Project are:
CCTA Smart Signals Systems Engineering Management Plan-Draft | Page 16
1. Traffic Signal Control (TSC) enables traffic signals to assign the right- of-way at intersections. Traffic Signal Controllers are the physical devices assigned to an intersection that are usually stored in traffic cabinets. They can control a single intersection, multiple closely spaced intersections, or a midblock crosswalk. Traffic Signal Controllers electrically switch signals to traffic lights and pedestrian walk signals. TSCs can be pretimed, semi- actuated, or fully actuated; meaning both vehicle and pedestrian signals can either be programmed to use predetermined duration and timing intervals or use vehicle and pedestrian detectors to activate a certain phase (change it from red to green) of the signals.
2. Communications (Fiber and/or Ethernet) in modern ITS networks require ever-increasing data rates to facilitate real-time communications between a wide variety of remote field devices and traffic control centers. Fiber optic links between controllers and traffic control centers provide greater b andwidth, longer transmission distances, and more signal immunity than twisted pair copper and coax options. Fiber Optic cables will be a necessity to install at select locations to provide this increased functionality to the traffic control center. With the cost of fiber up, wireless/ cellular communication , or Ethernet over Copper (EOC) will also be an option for this project to be within the project budget.
3. Hybrid Traffic Detection refers to the use of multiple sensor technologies to detect and monitor traffic on roadways . A hybrid detection system uses a combination of sensors, radars, cameras, and software to collect data on vehicle speed, volume, flow, vehicle classification, etc., in addition to providing the detection calls to the signal controller to operate the traffic signals. A hybrid traffic detection system can provide more reliable and detailed information on traffic, including the detection of vehicles, pedestrian, bicyclist, and other vehicle classifications, which can improve safety and mobility at the intersection.
4. Video Analytics are used to comply with California privacy laws while detecting events and objects and communicating this event to the traffic signal controllers or the traffic control centers. These devices detect vul nerable road users (i.e. pedestrians and bicyclists), motor vehicles, and their movements. These devices may use Pan Track Zoom (PTZ) camera technology which allows for a wider field of view and reliable control for remote operators. Video detection edge devices may be used or existing fiber communication to TMC can be used to inform users of special traffic events such as a car going the wrong way, a car on fire, a pedestrian jaywalking, and near miss collisions.
5. Signal Control and Prioritization (SCP) gives preferential treatment (priority) to facilitate the movement of fleet vehicles such as transit, emergency services, and commercial fleets through signalized intersections. TSP and EVP are subsets of SCP that give signal priority to transit and emergency vehicles respectively. The innovative method for setting up Signal Control Prioritization is to use cloud- based systems or Vehicle to Infrastructure (V2I) communication instead of installing intersection infrastructure.
6. Automated Traffic Signal Performance Measures (ATSPM) is a group of performance measures, data collection and data analysis tools that show real- time and a history of performance at signalized intersections.

6. Integration of the System
System Integration will be a joint effort of CCTA and selected System Integrator. The System Integrator will be responsible for leading the efforts for successful integration of the various components of the Project. The System Integrator will be responsible for developing the Integration Plan for the project, which working with vendors and contractors to get a clear understanding of the various methods that they will use to ensure successful integration of the developed components into a fully functioning system that meets the requirements from the RFP and other Contract documents.
System Integration will occur in a phased approach starting with elements combined into components which are then combined into subsystems and then into a system. As each phase is ready, it will be first tested as a standalone system before testing as part of the existing system. The exact testing to be performed will be detailed in the individual device acceptance test plans, the system acceptance test plan, and the Verification and Validation Plans.
7. Integration of the Systems Engineering
Effort
This project includes 19 cities/towns, county, Caltrans, and transit providers. The larger the number of teams, the more critical and important the integration efforts are. It is critical that each stakeholder understands their roles and responsibilities for the project and how they can support the tasks from the WBS. Table 5 identifies the roles and responsibilities and the stakeholders responsible for approval along with the decision gates for each of the tasks identified as part of the WSB outlined in Section 3:
Technical Planning and Control. Decision gates represent critical activities that must be satisfactorily completed and approved before a task is considered complete. Each team will need to be aware of the status of activities coming directly before tasks their team is responsible for, as well as communicating with teams on tasks coming directly after to assist with the transition between tasks.

8. Applicable Documents
The following is a list of references used in the development of the SEMP:
► FHWA/Caltrans Systems Engineering Guidebook for ITS, version 3.0, November 2009. ► Smart Signals Project Fact Sheet, CCTA.
CONTRA COSTA COUNTYWIDE SMART SIGNALS
Contra Costa Transporta�on Authority (CCTA) is leading a Countywide Smart Signals Project (Project) to upgrade traffic signal and communica�on systems at 328 intersec�ons within Contra Costa County throughout the 19 ci�es/towns and unincorporated communi�es located along major arterial streets and roads designated as Routes of Regional Significance.
PURPOSE + NEED | Exis�ng traffic
signal systems in most ci�es within Contra
Costa County consist of outdated legacy
systems that lack fiber and/or ethernet
base communica�on making traffic signal
synchroniza�on and coordina�on
between traffic signals difficult.
Addi�onally, most corridors need Signal
Control and Priori�za�on (SCP)
technologies that can promote transit
usage and mode shi�. These opera�onal
deficiencies result in severe traffic
conges�on within the ci�es which can
also lead to spillover on the freeways;
increasing commuter travel �mes,
greenhouse gas emissions, fuel
consump�on, and accidents.
SOLUTION | Implementa�on of the planned Intelligent Transporta�on System (ITS) elements will unify Contra Costa County’s signal technology and communica�on systems to op�mize traffic flow. It will provide an interconnected Advanced Traffic Management System (ATMS) with the ability to monitor traffic condi�ons in real-�me, safely, and efficiently manage incidents, and share informa�on between agencies and the public.
BENEFITS
SAFETY
Upgrading traffic signal equipment
and applying smart control
systems at intersec�ons will:
► Improve emergency service
response �me;
► Help first responders and law
enforcement manage traffic or
crime incidents; and
► Implement Video analy�cs
that can iden�fy near miss
situa�ons, prevent future
occurrences, and reduce
secondary accidents.
OPERATIONAL
IMPROVEMENTS
Signal synchroniza�on and
implementa�on of SCP
technologies will:
► Smooth traffic flow and
reduce idling;
► Increase average speed;
► Decrease travel �me and total
delay;
► Reduce greenhouse gas
emissions; and
► Increase transit reliability by
improving on-�me service.
TRAFFIC MANAGEMENT
ENHANCEMENTS
Shared control and improved cross
jurisdic�onal traffic management will:
► Provide ci�es and Caltrans access to
monitor all videos and signals in
real-�me;
► Op�mize day-to-day traffic
opera�ons and manage local events
through signal �ming op�ons;
► Effec�vely manage arterial traffic
during major incidents on the
freeway, evacua�ons, or major
events; and
► Enable ci�es to priori�ze transit and
emergency vehicles.
The goals of the project are to improve safety, optimize mobility, prepare for emerging transportation technologies, and advance Smart Cities.
