<br /> <br /> <br /> <br /> COOPERATIVE AGREEMENT NO. C-2-1992 <br /> ATTACHMENT A <br /> <br /> <br /> <br /> Task 2: Data Collection <br /> <br /> CONSULTANT shall collect the following data necessary to thoroughly understand <br /> existing traffic conditions in the study area and be able to develop optimal time-of-day <br /> traffic signal coordination plans, if applicable. <br /> 1. From the involved AGENCIES and or Authority, CONSULTANT shall collect existing <br /> timing charts/sheets, existing coordination plans, traffic as-built drawings, aerial <br /> photos, maps, traffic collision data as available, and collision diagrams for the study <br /> intersections, if available. CONSULTANT shall also collect any off the shelf plans <br /> (PS & E) for construction of any and all traffic signal coordination/synchronization <br /> related plans, specifications and estimates for the corridor. CONSULTANT, if <br /> requested by the involved AGENCY, will provide their own staff to review available <br /> records/plans and request copies of needed records/plans with a minimum of <br /> disruption to the involved AGENCY. <br /> <br /> 2. From the involved AGENCIES, CONSULTANT shall collect signal timing and signal <br /> priority preferences, including, but not limited to, those related to pedestrian and <br /> bicycle timing, phase sequence modifications and preferences, and special <br /> operations such as conditional service, coordination preferred phase re - service, <br /> and ring - barrier logic, as well as the timing optimization software preference. <br /> 3. CONSULTANT shall conduct seven-day 24-hour machine counts along each 1 mile <br /> segment of PROJECT. Additionally, CONSULTANT will collect 24-hour vehicle <br /> classification counts using a machine at four (4) locations on PROJECT to determine <br /> heavy vehicle (truck) percentage information. Data obtained from Saturday and <br /> Sunday counts will determine the necessity of weekend signal timing. <br /> <br /> 4. CONSULTANT shall conduct weekday and weekend peak period turning movement <br /> counts (TMC) at each and every of the PROJECT signalized intersections, including <br /> pedestrian and bicycle counts. No other types of TMC classification shall be <br /> necessary. Weekday counts shall be conducted for two hours of each peak period <br /> (AM, mid-day, and PM). If needed, after analyzing the seven-day 24-hour machine <br /> counts, weekend counts shall be conducted at each and every of the PROJECT <br /> signalized intersections for a single two hour Saturday mid-day peak period. For <br /> intersections with more than 2 through lanes in any of the approaches, a minimum of <br /> 2 people per intersection is required. <br /> a. CONSULTANT, APM, and Local AGENCIES shall determine locations for <br /> special video recording of bicycle and pedestrian activity for specific data <br /> collection in support of upcoming changes to the CA MUTCD. Video <br /> recording and data reduction shall be required at minimum 6 locations. <br /> b. CONSULTANT and designated sub consulting Traffic Counting Firm shall be <br /> cognizant of the fact that queuing of right turn vehicles or left turn vehicles <br /> <br /> <br /> 4 <br /> <br /> 25D-21 <br />
