El Camino Real Traffic 1Jtgnal System City of Redwood City 4. PROPOSED WORK PLAN The following work plan was developed based on : Scope of Services included in the RFQ Discussions with City staff Our experience with several similar projects involving multi-jurisdiction Compliance with the PVEA Grant objectives and Caltrans guidelines and references. MMA will refine the details of this work plan during the initiation (kick-oft) meeting based on detailed discussions and other existing information. TASK 1: COMMUNICATION ALTERNATIVES ANALYSIS The focus of this task: will be on the assessment of communication alternatives for the interconnection of study signalized intersections and if appropriate, communication between signal systems and the Central traffic management system for Caltrans (For example, the BI Tran Quicnet/2 software for Type 170 controllers), Redwood City's system and other agencies involved. The first step in this task will be to identify existing conditions related to traffic control communication for the study corridor as well as any existing communication links between study intersection and agencies. At the kick-offmeeting and shortly there after, we will research and obtain any documents, as-built plans, and other data re1ated to existing communication facilities. This will provide input for alternatives analysis as well as for PS&E preparation. There are currently some communication facilities including leased phone lines, and one segment of hardwire. It is our approach to utilize existing interconnect and other traffic control communication as much as possible. A master plan of communication system will be prepared that will include the following elements: Communication with Intersections - Various means of communication and media will be considered for evaluation. The feasibility analysis of the interconnect media is an area where MMA has been involved in numerous projects and has already access to the latest technology, pricing, integration, etc. We have evaluated, designed and, in several cases, implemented both hardwire, including twisted pair, fiber optics ("Smart Corridor", which was one of the first in California Sacramento, Modesto, Mission Viejo), leased telephone lines, coaxial cable, and wireless involving spread spectrum radio (Modesto, Petaluma and County of Santa Barbara), and Microwave (Lancaster, Las Vegas, South Bay, and others). An issue paper will be prepared that presents the final communication alternatives and Meyer, Mohaddes' recommendation. Each alternative will include detailed elements such as channel assignment, wiring diagrams, cost and associated equipment needed in the field and at the control center. The evaluation will include, at a minimum, the following elements: Technical advantages/disadvantages Meyer , Mohaddes Associates, Inc. 25 .'T""
