PRIMARY IMPLEMENTATION The following is an outline of the scope of services for Fairview Road PROJECT Primary Implementation. 1) Project Administration CITY shall provide general project administration, environmental processing, and quality control. The City of Santa Ana ("Santa Ana") shall provide support project management services for the project Intersections located within their jurisdiction and assist in maintaining the Fairview Road PROJECT schedule. a) Data Collection The CITY will assemble with the assistance of Santa Ana the necessary data to understand the existing traffic conditions for the Fairview Road PROJECT and Its respective traffic signal operations. This shall Include, at minimum, the following: • All data, documents, plans, photos, etc. related to each Fairview Road PROJECT Intersection within the past two years; • Local agency timing preferences or policies for all modes of travel and special Intersection treatments; and • Manual and Machine Traffic counts for highway links and intersections for weekday and weekend time periods for all modes of travel. Special 72 -hour video counts will be conducted along the corridor with established special modal use. b) Field Reviews CITY shall conduct Fairview Road 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 8.0 and Tru — Traftic 9.0 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. Santa Ana 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 Mile, 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 Fairview Road PROJECT traffic signal synchronization. Summary reports shall be prepared by CITY in coordination with Santa Ana to identify improvements in metrics from the Before to After conditions. The Before and After Study shall constitute the Fairview Road PROJECT Final Report. Additionally, this report shall document improvements accomplished and recommend procedures for continuing maintenance, surveillance, and evaluation of the coordinated signal system. Page 2 of 3
