Costa Mesa <br />The City is proposing the installation of interconnect conduit with fiber optic cable <br />along with Ethernet Communication equipment and CCTV camera system at <br />various locations. The City is also proposing traffic signal cabinet & foundation <br />upgrades at nine intersections. In addition, the City is proposing installation of <br />Uninterruptible Power Source, Emergency Vehicle Preemption and replace <br />pedestrian heads with countdown types at several locations. The City is also <br />proposing upgrades to the existing Traffic Management Center. <br />2. Ongoing Maintenance and Operation <br />Ongoing maintenance and operation period will start after signal timing is <br />implemented and last for a period of two years, It will consist both of (1) monitoring <br />and improving optimized signal timing and (2) communications and detection support. <br />Ongoing Maintenance will not be provided for Cahrans intersections, <br />Descriptions of both are provided below: <br />a. Monitoring and improving optimized signal timing <br />After the Pcimar Implementation of the new coordination parameters, the corridor <br />will monitored and fine time([ monthly or as needed for the duration of two years. <br />Improvements to the signal synchronization will be made according to the test <br />drives and changing field conditions. <br />b. Communications and detection support <br />The communication and detection systems will be monitored and repaired as <br />necessary to maintain efficient corridor synchronization throughout the project <br />schedule. <br />e. Final report <br />After the three year grant period, a final report for the project will be developed <br />and will include before an([ after studies, updates of the results from Cite ongoing <br />maintenance and operations phase and will establish completion of all CTPP <br />Guideline requirements. <br />7 <br />
