MEMORANDUM OF UNDERSTANDING NO. C-9-0825 <br />EXHIBIT A <br />e. Information required to update the completed design phase <br />documentation by others <br />f. Recommendations Required to Complete the Remaining TSS Design <br />Finalization Tasks <br />The report shall be provided in sections in accordance to each design phase <br />document reviewed. <br />Westminster/17th Street BRT Corridor TSS Design Finalization Services <br />deliverables (in part to include): <br />C6a. Technical memorandum detailing findings of the completed design phase <br />documentation review. <br />3.3.7 TASK C-7: WESTMINSTER/17TH STREET BRT CORRIDOR TSS DESIGN <br />FINALIZATION SERVICES -SIGNAL TIMING OPTIMIZATION <br />Previous consultant developed a Draft model of the study area approved by the <br />AUTHORITY. Previous consultant calibrated the draft model based on travel <br />time, delay studies, field observations of queue lengths, and saturation flows for <br />heavy movements at key intersections. CONSULTANT shall review, verify, and <br />update the previously prepared Draft model of the study area, as defined in this <br />task. Signal synchronization optimization shall be conducted in Synchro 7.0 and <br />optimization shall be augmented with Tru -Traffic TS/PP version 8.0. <br />If the CONSULTANT elects to use alternative methodologies to augment or <br />replace certain aspects of the Synchro model such as pre-processing of certain <br />data sets or split analysis, and/or other types of processes, the CONSULTANT <br />shall describe these operations in detail in the report with supporting <br />documentation as to why these processes were used in lieu of or in <br />augmentation to the Synchro model. These methodologies shall also be <br />described in detail in the CONSULTANT'S proposal for this project. <br />CONSULTANT shall develop an operational model within SimTraffic software. <br />The SimTraffic model will identify those local areas or portions of the project that <br />need special operational analysis of queue interactions such as starvation or <br />spillback. The operational analysis shall be used to supplement the "Before" and <br />"After" studies, to understand the effects of planned corridor improvements, fine <br />tune timing plans prior to implementation, and to analyze the additional <br />operational improvements as recommended by CONSULTANT. The entire <br />corridor does not have to be micro -simulated. Analysis shall be performed on <br />corridor segments that have queuing, starvation, spillback, or other problems <br />which can be mitigated by the SimTraffic program. <br />CONSULTANT shall develop final optimized signal timings using Synchro 7.0, <br />and recommend any changes to the signal phasing at each signalized <br />intersection that may improve the efficiency of operations.
