PRIMARY IMPLEMENTATION <br />The following is an outline of the scope of services for Fairview Road PROJECT Primary <br />Implementation. <br />1) Prolect Adminlstratior� <br />CITY shall provide general project administration, environmental processing, and quality control. <br />The City of Santa Ana ("Santa Ana") shall provide support project management services for the <br />project Intersections located within their jurisdiction and assist in maintaining the Fairview Road <br />PROJECT schedule. <br />a) ©ata Collection <br />The CITY will assemble with the assistance of Santa Ana the necessary data to understand <br />the existing traffic conditions for the Fairview Road PROJECT and its respective traffic <br />signal operations. This shall Include, at minimum, the following: <br />• All data, documents, plans, photos, etc. related to each Fairview Road <br />PROJECT intersection within the past two years; <br />• Local agency timing preferences or policies for all modes of travel and special <br />Intersection treatments; and <br />• Manual and Machine Traffic counts for highway links and intersections for <br />weekday and weekend time periods for all modes of travel. Special 72 -hour <br />video counts will be conducted along the corridor with established special <br />modal use. <br />b) Field Reviews <br />CITY shall conduct Fairview Road PROJECT field reviews to verify collected data including <br />geometric layout, inventory of existing traffic signal control and communications, and any <br />and all factors that impact or affect signal progressions. <br />2) Signal Synchronization Timing <br />CITY shall develop a signal synchronization model using Synchro and Sim Traffic 8.0 and Tru — <br />Traffic 9.0 to verify the operation of existing timing and then produce and evaluate potential <br />timing changes that would improve or refine the corridor traffic flows through improved <br />optimized signal operations. Santa Ana shall be involved in the review and validation of the <br />recommended signal timing. The OCTA Corridor Synchronization Performance Index (CSPI) <br />combines Average Speed, Stops per Mile, and Greens per Red (number of Intersections <br />successfully traversed on a Green Light vs. Stopped by a Red Light) into a composite index. <br />The CSPI shall be the defined metric in this evaluation. <br />The CITY shall utilize the approved Optimized Signal Timing and implement the timing into the <br />central and field controller systems and provide Fine Tuning services. The After Study Travel <br />Time Runs shall be performed and the Before to After comparison CSPI shall then be <br />determined. <br />3) Before and After Studies and Reports <br />CITY shall conduct real-time floating car "runs" In each direction during the planned (Before) <br />and implemented (After) time periods of Fairview Road PROJECT traffic signal synchronization. <br />Summary reports shall be prepared by CITY in coordination with Santa Ana to identify <br />improvements in metrics from the Before to After conditions. The Before and After Study shall <br />constitute the Fairview Road PROJECT Final Report. <br />Additionally, this report shall document improvements accomplished and recommend <br />procedures for continuing maintenance, surveillance, and evaluation of the coordinated signal <br />system. <br />Page 2 of 3 <br />25C-15 <br />
