<br /> <br /> <br /> <br /> COOPERATIVE AGREEMENT NO. C-2-2030 <br /> ATTACHMENT A <br /> segments for the 'Before' and 'After' runs. CONSULTANT shall notify and receive <br /> approval from APM on number of runs and segments to be accomplished. <br /> <br /> Project travel-time data will be collected using the floating car method, a laptop <br /> computer, a GPS receiver unit, and Tru-Traffic v 10.0, only. <br /> <br /> 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. Ideally, the analysis should include the floating car data and data <br /> collected as part of Task 2. However draft versions of the report can include previously <br /> collected traffic, travel time, or other data, if considered relevant and available. The <br /> evaluation report shall provide a very good understanding of traffic patterns on <br /> PROJECT throughout the weekdays and throughout the weekend. Tru-Traffic Version <br /> 10.0 has the OCTA Corridor Synchronization Performance Index (CSPI) Calculation <br /> formulas available for use as well as the calculations for the latest emissions for GHG <br /> and other MOEs. These functions shall be utilized by the CONSULTANT in the draft <br /> preliminary, draft final and final reports as specified herein. <br /> <br /> The CONSULTANT shall perform due diligence with regard to existing and proposed <br /> timing operations on arterials that intersect with the PROJECT. <br /> <br /> CONSULTANT shall prepare a memorandum and present the findings to the Authority <br /> outlining the findings of the `Before' field study. The Authority may request a <br /> presentation on the traffic patterns on PROJECT Scope and possible synchronization <br /> strategies to address the traffic patterns (optimizing the fill corridor versus optimizing <br /> segments identified with natural traffic breaks) to provide direction on the preferred <br /> signal timing strategy. Any requested presentation shall include as much of the turning <br /> movement, 24-hour machine counts, travel time, earlier city counts, etc. as available. <br /> CONSULTANT shall finalize the memorandum based on comments received from the <br /> Authority Project Manager and other involved AGENCIES and after incorporating the full <br /> set of data collected by CONSULTANT as part of Task 2. <br /> <br /> Deliverables - Task 4: <br /> A memorandum documenting the results of the 'Before' study is to be distributed to the <br /> APM and AGENCIES as a discussion item. More detailed analysis of project results <br /> shall be included in Task 8: Project Report. <br /> 1. Electronic versions of all data files and memorandum to all PARTIES and <br /> AGENCIES. <br /> <br /> <br /> Task 5: Signal Timing Optimization and Implementation <br /> <br /> CONSULTANT shall work with the APM and AGENCIES to develop a model of the <br /> study area and calibrate the model based on field observations of existing conditions. <br /> Signal synchronization optimization shall be conducted in Synchro 8.0. The corridor <br /> model must be consistent with all aspects and seamlessly interface and interlace with <br /> <br /> <br /> 25D-67 <br />
