RFP: Turn-Key Signal Infrastructure & Coordination Improvements - Baker Placentia Victoria and 19th, Costa Mesa, CA

Signal timing along the three (3) continuous/contiguous project corridors requires updating to meet current traffic demands and patterns. The goals of the project are to update timing, coordinate the roadway between the jurisdictions and also to integrate the traffic signals, communication, and ITS components optimally at City’s TMC. The scope of work is developed to improve these conditions. Improvements at the Caltrans signals will primarily be updating timing and coordination. Existing field conditions and signal timing plans for intersection and corridor operations shall be evaluated and conditions documented. The consultant shall model, analyze and optimize individual intersection conditions and submit for review by the City, prior to analysis of arterial coordination studies. The Consultant shall use the latest version of Synchro 11 for the analysis. The intersection and arterial signal analysis and optimization approach and all software programs to be utilized by the Consultant shall be described in the proposal. New timings shall be developed, implemented, tested and refined to optimize signal coordination and vehicle progression. A minimum of five separate timing plans per intersection shall be prepared covering the AM peak period, PM peak period, midday, evening (if needed), and weekend. Full scale “draft” Time-Space Diagrams (500’ per inch horizontal/50 second per inch vertical) shall be prepared for each timing pattern and presented to the City for each corridor for review, with final diagrams prepared documenting final coordination timings. The timing study shall account for the network-wide coordination system and respective impact/benefits to cross street progression. Network traffic flow shall not be compromised. The professional services scope of work is intended as a "Turnkey" project. Bonds required at bidding.
