(9) CITY OF SANTA ANA 3. Ideally, the analysis should include the floating car data and data collected as part of Task 2. However draft versions of the report can include previously collected traffic, travel time, or other data, if considered relevant and available, until the full set of data collected by CONSULTANT as part of Task 2 is available. 4. The memorandum shall provide a very good understanding of traffic patterns on PROJECT throughout the weekdays and throughout the weekend. The CONSULTANT shall perform due diligence with regard to existing and proposed timing operations on arterials that intersect with the PROJECT. 5. Tru-Traffic has the OCTA CSPI calculation formulas available for use, as well as the calculations for the latest emissions for GHG and other MOE's. 6. CONSULTANT shall finalize the memorandum based on comments received from Santa Ana and other involved agencies. G. Consultant shall present to the project team the traffic patterns on project scope and possible synchronization strategies to address the traffic patterns (optimizing the fill corridor versus optimizing segments identified with natural traffic breaks) to provide direction on the preferred signal timing strategy. Any requested presentation shall include as much of the turning movement, 24-hour machine counts, travel time, earlier city counts, etc. as available. Sub -Task 2.: 'After' Travel Time Studies Following the implementation of all system and timing enhancements, consultant shall schedule 'After' travel time studies to measure the effectiveness of the project. Since the Kraemer Boulevard/ Glassell Street/ Grand Avenue corridor is part of the OCTA Countywide Baseline Project, OCTA is currently collecting data, developing traffic signal synchronization timing, and will implement and fine tune new timing for all the fifty-seven (57) agency signals along this corridor, except the Caltrans signals. The Consultant shall coordinate the After Travel Time Studies with OCTA's Countywide Baseline Project. A. The consultant shall conduct an 'After' field study representative of the times and days for which synchronization plans were developed. The 'After' study must be conducted in the same manner and contain the same MOE's as the'Before' study in order to evaluate the improvements of the synchronization plans. B. At least five (5) runs will be completed in each direction for each of the three weekday timing plans (AM, mid -day, and PM), and at least five (5) runs will be completed in each direction during the Saturday midday plan. C. Project travel -time data shall be collected using the floating car method, a laptop computer, a GPS receiver unit, and the methodologies and software to match the 'Before' study, exactly. MOE's should be compiled for the optimized corridor using the floating car method output in IatestTru- Traffic and then from Synch ro/SimTraffic. 9
