b) Field Reviews CITY shall conduct Bear Street PROJECT field reviews to verify collected data including geometric layout, Inventory of existing traffic signal control and communications, and any and all factors that impact or affect signal progressions. 2) Signal Synchronization Timing CITY shall develop a signal synchronization model using Synchro and Sim Traffic 10.0 and Tru — Traffic 10.0 to verify the operation of existing timing and then produce and evaluate potential timing changes that would improve or refine the corridor traffic flows through Improved optimized signal operations. The PARTICIPATING AGENCY shall be involved in the review and validation of the recommended signal timing. The OCTA Corridor Synchronization Performance Index (CSPI) combines Average Speed, Stops per Mlle, and Greens per Red (number of intersections successfully traversed on a Green Light vs. Stopped by a Red Light) into a composite index. The CSPI shall be the defined metric in this evaluation. The CITY shall utilize the approved Optimized Signal Timing and implement the timing into the central and field controller systems and provide Fine Tuning services. The After Study Travel Time Runs shall be performed and the Before to After comparison CSPI shall then be determined. 3) Before and After Studies and Reports CITY shall conduct real-time floating car "runs" in each direction during the planned (Before) and implemented (After) time periods of Bear Street PROJECT traffic signal synchronization. Summary reports shall be prepared by CITY in coordination with the PARTICIPATING AGENCY to identify improvements in metrics from the Before to After conditions. The Before and After Study shall constitute the Bear Street PROJECT Final Report. Additionally, this report shall document improvements accomplished and recommend procedures for continuing maintenance, surveillance, and evaluation of the coordinated signal system, 4). Engineering Design, Review. and Procurement/Construction — Support Infrastructure PARTICIPATING AGENCY shall provide sufficient staffing to provide Engineering Design Review of design documentation. If design documentation is provided by the PARTICIPATING AGENCY for Bear Street PROJECT, the Engineering Design Review requirement shall be satisfied. Purchase and construction/installation of the requested traffic signal Infrastructure and upgrades, software, licenses, or other components as approved in the application shall be by the CITY in the name of and for the end user PARTICIPATING AGENCY. The CITY shall work with the PARTICIPATING AGENCY to coordinate design, Identification of applicable standards/specifications, purchasing and/or installation of the required signal improvements. Design and other technical support to implement the upgrades shall be subject to the designated cost estimate. The budget for these Improvements is fixed to the approved budget and will be subject to revised scope or additional contributions. The highest priority improvements shall be those that are required to optimize signal timing. The PARTICIPATING AGENCY shall waive all fees for permits and inspections and shall provide sufficient professional staffing to provide construction sunnnrt and inspection sen!ices to Bear Street PROJECT.
