Master Plan Preparation The objectives of the Traffic and Street Light Master Plans are to develop a multi -step process to implement upgrades to the existing TMC, develop solutions and strategies for upgrading the City's traffic signal/street light system, and developing a plan for improved citywide communications to all signalized intersections. The master plans will leverage the existing traffic signal/street light system and infrastructure to the greatest extent possible to create a plan for improved inter -jurisdictional coordination. In adherence with the systems engineering process, Iteris will prepare the draft and final Master Plans, based on the details of the proceeding deliverables prepared in the previous sub - tasks, including client comments. Details from the Technical Memoranda prepared in the previous tasks will collectively be compiled to create the Traffic Signal and Street Light Master Plans. The Master Plans will detail the phased deployment of the recommended infrastructure solutions including an improved traffic signal communications system, traffic signal system upgrades and other traffic management and ITS strategies as appropriate. A key element of this task will be to create a prioritized ranking of the recommended projects based upon needs, project cost, and availability of existing infrastructure, level of service goals, project duration and schedule. This document will discuss design alternatives as well as staging techniques to allow the City to achieve its final goal — deployment of a comprehensive citywide traffic signal/street light system that also serves to support citywide communications. The Plan will include the following elements: • Prioritized listing of projects • Utilize the existing and planned infrastructure to the extent possible • Cost estimates associated with each project • Schedule and Critical Path for the deployment of the projects • Summary matrix of projects by priority and implementation schedule • Capital improvements and associated costs • Operations, maintenance and life -cycle costs • Interagency coordination issues (Intertie, coordinated operations, etc.) • Multi -jurisdictional coordination issues • Detail roles and responsibilities of the various stakeholders for the corresponding projects • Identify applicable standards The Master Plans will identify the needs and readiness to integrate with certain technological advancements such as connected/automated vehicles. Iteris has, in the past, contract with the United States DOT to help develop and implement the design architecture of connected vehicles for future connectivity. Connected/automated vehicles apply new communication capabilities, new data sources, and security to the ITS environment. The Master Plan will detail out the future of the City's ITS network with ability to expand as connected vehicles become more commonplace in the market. The Master Plans will also detail a series of projects to deploy solutions that will include expansion of the existing communications network and additional field devices. The corresponding systems will likely require coordination between City Departments for the operations and maintenance (O&M) of the system. It is imperative to identify the roles and responsibilities to determine who will maintain the system and hardware, and the corresponding costs for this maintenance.
