(9)CITY OF SANTA ANA <br />Sub -Task 2.3: 'Before' Travel Time Studies <br />Travel time studies will be used to measure the effectiveness of the project improvements and <br />timing plans. At a minimum, consultant shall conduct the following travel time studies to measure <br />the traffic conditions prior to the development and implementation of new timing plans. <br />Since the Kraemer Boulevard/ Glassell Street/ Grand Avenue corridor is part of the OCTA <br />Countywide Baseline Project, OCTA is currently collecting data, developing traffic signal <br />synchronization timing, and will implement and fine tune new timing for all the fifty-seven (57) <br />agency signals along this corridor, except the Caltrans signals. The Consultant shall coordinate <br />the Before Travel Time Studies with OCTA's Countywide Baseline Project. <br />A. Project travel -time data shall be collected using the floating car method, a laptop <br />computer, a GPS receiver unit, and Tru-Traffic. <br />B. Consultant shall complete, at least, five (5) runs in each direction for each of the three <br />weekday timing plans (AM, mid -day, and PM) and one Saturday mid -day plan. Number <br />of runs shall be consistent for both directions and time periods. Based on engineering <br />judgment and in conjunction with approval, consultant should subdivide the corridor into <br />contiguous segments for the 'Before' and 'After' runs. Consultant shall notify and receive <br />approval from Santa Ana on number of runs and contiguous segments to be <br />accomplished. <br />C. Consultant shall conduct a 'Before' field study report representative of the times and days <br />for which synchronization plans will be developed. The report shall identify Measures of <br />Effectiveness (MOE) to evaluate the effects of the synchronization plans. <br />D. MOE's to evaluate shall include, at a minimum, traffic flow, travel time, average speed, <br />number of stops per mile, number of intersections traversed on green vs. stopped by red <br />(Greens per Red) (note: Average Speed, stops per Mile, and Greens per Red are the new <br />OCTA MOE, Corridor Synchronization Performance Index (CSPI)), fuel consumption <br />reduction, pollution reduction, and other pertinent items. <br />E. The CONSULTANT shall include the CSPI as part of the MOEs as they are easily <br />identifiable by lay persons relevant to demonstrating corridor improvements. The identified <br />MOE's shall be compiled for the corridor using the floating car method and from latest <br />Synchro and from Tru-Traffic. <br />F. Consultant shall prepare a memorandum and present the findings to Santa Ana and <br />partnering agencies outlining the findings of the 'Before' field study. <br />1. The report shall identify MOE to evaluate the effects of the synchronization plans. <br />The identified MOE's shall be compiled for the corridor using the floating car <br />method and from latest Synchro and from Tru-Traffic. <br />2. The report shall address likely optimization strategies for signal synchronization, <br />specifically focusing on how to consider PROJECT optimization: end -to -end vs. <br />coordinated zones. <br />8 <br />
