TUSTIN AVENUE/ROSE DRIVE RTSSP GRANT APPLICATION OCTOBER 2019 SECTION 4: PRELIMINARY PLANS FOR THE PROJECT Primary Implementation (PI) The Primary Implementation phase will last approximately one year and include the following elements: Task 1: Task 2: Task 3: Task 4: Task 5: Task 6: Project Administration Data Collection Field Review and Plans Specifications, and Estimates Signal Timing Optimization and Implementation The City of Orange will lead the project using contracted consultant staff to optimize signal synchronization timing along the Tustin Avenue/Rose Drive corridor. Orange shall perform normal day to day project administration duties. Local agency staff will perform local project administration duties. Project budget shall include time and funding for agency outreach and coordination. Orange will be responsible for all fiduciary elements of the project including dissemination of any funds and/or collection of funds from the partnering agencies. Project Administration services by Orange will include but not be limited to administration, engineering and design, coordination, presentation and other related responsibilities to ensure a timely project delivery. The budget shall include time and funding for outreach and cooperative agreement development and matching funds required by the partners. The Consultant contracted by the City of Orange will collect data necessary to thoroughly understand existing traffic conditions in the study area, develop a concept of operations, and be able to develop optimal time-of-day traffic signal coordination plans for specific zones and traffic generators as applicable. The City of Orange's contracted consultant shall be a qualified traffic engineering consultant with the ability to complete the engineering design of the fiber upgrade and communications for the project. The Consultant will review the geometric layout, existing traffic signal equipment, and signal synchronization related infrastructure to identify any deficiencies for each intersection and along the whole corridor/route. The review shall include an assessment of the existing intersection geometry, traffic conditions, traffic signal control equipment, and telemetry/interconnect facilities along the corridor and of each intersection using observation, available as-built plans, consultation with the local AGENCIES, and Party supplied aerial photos. Based on the initial assessment by the partnering agencies and with their respective permission, the CONSULTANT shall inspect the interior of each traffic control cabinet, inspect the telemetry systems and determine their respective condition and make recommendations for equipment upgrades. The project scope shall encourage innovative solutions and also account for unforeseen conditions. The City of Orange's contracted consultant shall be a qualified traffic engineering consultant with the ability to conduct "before" floating car travel runs prior to timing implementation. The Consultant will conduct a ‘Before’ field study report representative of the times and days for which synchronization plans will be developed. The report shall identify Measures of Effectiveness (MOE) to evaluate the effects of the synchronization plans. MOE’s will likely include traffic flow, travel time, average speed, number of stops per mile, number of intersections traversed on green vs. stopped by red (Greens per Red) (note: Average Speed, Stops per Mile, and Greens per Red are the new OCTA MOE, Corridor Synchronization Performance Index (CSPI)), fuel consumption reduction, pollution reduction, and other pertinent items. Agencies with Automated Signal Performance Measures should provide any data or analytics as part of the Before Study. Corridor "Before" Study Corridor "After" Study The City of Orange's contracted consultant shall be a qualified traffic engineering consultant with the ability to conduct "after" floating car travel runs after timing implementation. The Consultant will Synchronization or coordination will be inter-jurisdictional in nature. All existing special generators such as schools or attractive businesses, traffic patterns, flows, and conditions will be taken into account. Synchronized timing will be developed for the AM Peak, PM Peak, Mid-day Peak and Weekend Peak. Crossing Arterial projects that have recently been timed will be considered as part of the project. Timing plans will be developed that assist traffic in getting to its destination without regard to physical or jurisdictional boundaries. 4
