TUSTIN AVENUE/ROSE DRIVE RTSSP GRANT APPLICATION OCTOBER 2019 conduct an After' field study representative of the times and days for which synchronization plans will be developed. The After'study must be conducted in the same manner and contain the same MOE's as the Before' study in order to evaluate the improvements of the synchronization plans. MOE's should be compiled for the optimized corridor using the floating car method. Agencies with ATSPM shall provide any data and analytics to complement both the before and after studies. Task 7: Synchronization System Construction The City of Orange will use qualified traffic engineering consultants to design all infrastructure and equipment upgrades based on Section 5. All installations and upgrades will be per the owning agencies' standards. Details of equipment upgrades are tabulated in Tables I and IL Since the agencies have requested Orange to be the lead on this project, Orange will enlist a qualified contractor on a standard procurement basis to construct the facilities based on State and local agencies standards, specifications, and special provisions as developed by the consultant. Task 8: Primary Implementation Project Report The contracted consultant will develop a before and after study for the project. This report will be completed after the Primary Implementation is completed and will include the following: • Introduction/project description: a summary of the project including the purpose, background, and objectives of the project. • Data collection: a summary of the data collected as part of the effort including the traffic counts, phasing, lane configurations, etc. • Traffic signal systems improvements: a summary of the implemented traffic signal systems improvements by city. • Signal timing optimization: a summary of the development and implementation of updated signal timing including the models, selected cycle lengths, intersection groupings, etc. • Results: the study will contain directional morning, mid -day, evening, and weekend peak periods using travel times, average speeds, green lights to red lights, stops per mile, and the derived corridor synchronization performance index (CSPI) metric. This information shall be collected both before and after any signal timing changes have been made. Additional details based on the Final Report Template will also be included. • Benefits to cost analysis: project benefits resulting from signal synchronization will be evaluated based on the before and after study results. Savings will be calculated for travel time, fuel consumptions, vehicle maintenance, Greenhouse Gas (GHG) reduction, and a final benefit cost ratio. • Future signal corridor improvements: recommendations for system and equipment enhancements to improve traffic flow and signal synchronization will be provided. • Conclusion: a summary of the before and after study and its findings. The City of Orange shall be responsible for submission of this document along with relevant backup information to OCTA Programs for close out of the PI Phase, Task 9: On -going Maintenance & Operations The City of Orange's contracted consultant shall provide "on -call" signal timing support services for a period of two years or 24 months fallowing the complete closeout and all payments made for the Primary Implementation phase, to address any future adjustments that may be needed during this period. Depending on the nature of the adjustment, the Consultant may accomplish the fine-tuning adjustments remotely from the office through the traffic management systems. During this 24-month period the Consultant will be prepared to review any project intersection requested within (24) hours of written notice, including observing and fine-tuning the signal timing. The Consultant will also assist with resolving communications and detection issues along the corridor. The Consultant will drive the length of the project arterial during all designated corridor synchronization timing plan hours of operation on a monthly basis in order to verify that the synchronization timing is working as designed, and complete any necessary adjustments. Monthly driving times will consist of a full 12-hour weekday and a 4-hour Saturday. All drives shall be documented. A copy, limited to jurisdictional boundaries, shall also be sent to each agency. At the end of the 2-year O&M phase, the Consultant shall prepare a memorandum to summarize the O&M phase. It should, at the minimum, include when travel runs were conducted, issues and solutions throughout the phase, and recommendations for future improvements. Revl: 4/7/2021 Page 6 of 23
