..,_4,,.. 4 CITY OF SANTA ANA A. Coordinate with OCTA Countywide Baseline Project to obtain available 24-hour mid-week and 24-hour weekend machine counts along the project. 24-hour data will be used to determine the peak hour counts and synchronization. B. Coordinate with OCTA Countywide Baseline Project to obtain available vehicle classification counts at all locations where 24-hour counts are taken. C. Consultant shall conduct weekday and weekend peak period turning movement counts (TMC) at the four (4) Caltrans intersections. a. Weekday TMC counts shall be conducted for two hours of each peak period (AM, Mid-day, and PM). b. Weekend TMC counts shall be conducted for one 2-hour peak period (either on Saturday or Sunday). Exact time and day to be determined from 24 hours counts. D. Consultant shall collect signal timing and signal priority preferences, including, but not limited to, those related to pedestrian and bicycle timing, phase sequence modifications and preferences, and special operations such as conditional service, coordination preferred phase re-service, and ring-barrier logic, as well as the timing optimization software preference at the four(4) Caltrans intersections. E. Consultant shall perform thorough field inventory of the four(4) Caltrans intersections including traffic signal controller, related hardware, geometric layout and existing timing parameters as necessary for timing analysis. F. All counts shall be summarized in Microsoft Excel format. Counts shall also be summarized in a Comma Separated Values (CSV) file in the Universal Traffic Data Format (UTDF) for direct volume import into Synchro by peak period. Copies of the raw data count sheets shall also be provided to each involved Agencies and City of Santa Ana. Sub-Task 2.2: Field Review Consultant shall collect, at a minimum, the following field review necessary to thoroughly understand existing traffic conditions in the study area. A. Consultant shall 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. Consultant shall use a standard field form developed by consultant for this review that accounts for each piece of intersection data required. With permission of the local agencies, 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. Before and after photos of each cabinet shall be included with the field review inventory. Consultant is advised that certain infrastructure and equipment upgrades have been identified previously by the agencies and shall be a requirement of this project. These items are identified subsequently within this document. B. Consultant shall also include an identification of all planned and programmed improvements (widening projects, intersection improvements, etc.) on the study corridor. 6
