<br /> <br /> <br /> <br /> <br /> AGREEMENT C-1-3022 <br /> MacArthur Boulevard/Talbert Avenue <br /> <br /> ATTAC HM ENT A <br /> • Local agency timing preferences or policies for all modes of travel and special <br /> <br /> intersection treatments <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 at up to eight (8) intersections along the <br /> <br /> corridor with established special modal. use. <br /> b) Field Reviews <br /> AUTHORITY shall conduct PROJECT field reviews to verify collected data <br /> including geometric layout, inventory of existing traffic signal control and <br /> <br /> communications, and any and all factors that impact or affect signal <br /> progressions. AUTHORITY in coordination with the PARTICIPATING <br /> AGENCIES shall identify mitigations for the existing traffic signal control <br /> equipment or geometric layouts to determine recommended PROJECT related <br /> <br /> improvements <br /> 2) Signal Synchronization Timing <br /> The AUTHORITY shall develop a signal synchronization model using Synchro and Sim <br /> Traffic 8.0 and Tru Traffic 9.0 to verify the operation of existing timing and then produce <br /> <br /> and evaluate potential timing changes that would improve or refine the corridor traffic flows <br /> through improved optimized signal operations. The PARTICIPATING AGENCIES shall be <br /> involved in the review and validation of the recommended signal timing. The OCTA Corridor <br /> Synchronization Performance Index (CSPI) combines Average Speed, Stops per Mile, and <br /> <br /> Greens per Red (number of intersections successfully traversed on a Green Light vs. <br /> Stopped by a Red Light) into a composite index. The CSPI shall be the defined metric in this <br /> evaluation <br /> The AUTHORITY shall utilize the approved Optimized Signal Timing and implement the <br /> <br /> timing into the central and field controller systems and provide Fine Tuning services. The <br /> After Study Travel Time Runs Shall be performed and the Before to After comparison CSPI <br /> shall then be determined <br /> <br /> <br /> 3) Before and After Studies and Reports <br /> AUTHORITY shall conduct real-time floating car "runs" in each direction during the planned <br /> (Before) and implemented (After) time periods of PROJECT traffic signal synchronization. <br /> Summary reports shall be prepared by AUTHORITY in coordination with the <br /> <br /> <br /> <br /> <br /> 25B-18 <br />
