Task 4: Signal Timing Optimization and Implementation The project aims to improve efficient traffic operations along the regional corridor for all modes of transportation. As part of this task, consultant will evaluate existing timing conditions, generate, implement and fine-tune recommended optimized signal timing plans based on available data and improvements planned in the project. Guidelines and standards for signal synchronization continue to evolve with the innovations in technology. City of Santa Ana encourages consultant to present progressive and forward-thinking optimization solutions for more efficient operations on this project. As stated in Task 2, this corridor is part of OCTA's Countywide Baseline Project and is currently collecting data, developing traffic signal synchronization timing, and will implement and fine tune new timing for all the fifty-seven (57) agency signals along this corridor, except the Caltrans signals. Therefore, Signal Timing Optimization and Implementation for this project will be limited to the four (4) Caltrans intersections. The Consultant shall closely coordinate Signal Timing Optimization and Implementation with OCTA's Countywide Baseline Project. Consultant shall coordinate with Caltrans, City of Santa Ana and Partner Agencies to execute a Cooperative Agreement with Caltrans for this Task. Sub-Task 4.1: Base Network A. Consultant shall work with the City of Santa Ana, Caltrans and Partner Agencies to develop a model of the four (4) Caltrans intersections and study area and calibrate the model based on field observations of existing conditions. B. Signal synchronization of existing and optimized networks shall be conducted in latest Synchro software. The consultant must be cognizant of the version of Synchro that the receiving Agency is using and provide any files in that version. C. The corridor model must be consistent with all aspects and seamlessly interface with the Countywide Baseline Project. The project shall be developed with latest Synchro and 18
