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