4 RI <br />City of Santa Ana <br />Local Signal Synchronization Plan <br />support certain newly developed advance functions. The City plans to upgrade all controllers to <br />Advance Traffic Controllers to prepare for advanced traffic signal performance measures, <br />transit signal priority and connect vehicle technology. <br />The majority of Santa Ana's traffic signal cabinets are Type 332 which are built to conform to <br />the widely used Caltrans TEES standards. The Type 332 cabinets utilize rack mount equipment <br />for the output file, input files, PDA, and other components that are in the cabinet. The City also <br />has numerous legacy cabinets that are National Electric Manufacturers Association (NEMA), <br />Type P (TS1) and Type G (Pole Mount). The City currently plans on upgrading all cabinets to the <br />preferred Type 332 or Advanced Traffic Controller Cabinet (ATCC). Both cabinets take up the <br />same footprint, while the ATCC operates with reduced equipment, allowing for additional rack <br />space for future advance technology needs. <br />C. Traffic Signal Video Monitoring System <br />The City has installed closed circuit television (CCTV) cameras at just over one hundred (100) <br />intersections. These cameras are installed to assist the City with a multitude of tasks that <br />include observing traffic conditions, road construction activities, incident management and <br />identifying other issues on the roadway that directly leads to improved response time in <br />alleviating traffic concerns. The City also have video feeds from the Video Detection System <br />(VDS) locations with IP communications, which can be viewed remotely from the TMC and the <br />Remote TMC. The VDS feeds allow City to quickly diagnosed vehicle and bicycle detection issues <br />and make better informed timing adjustment decisions. <br />The City's CCTV cameras are managed and monitored through Milestone Video Management <br />software. All Cameras are available to City staff at workstations running Milestone VMS Client <br />software and are available to the video wall from the display PCs. City staff actively utilize the <br />CCTV cameras to monitor traffic conditions along the busiest and most traveled corridors and <br />intersections. <br />D. Traffic Signal Communication <br />The City currently uses a combination of twisted wire pair (TWP), Fiber Optics (FO), and wireless <br />radios for field device communications. Most of the traffic signals communication is via the City <br />Page 1 1 2023 <br />
