_ _ __ _ Subtask 3.2.3-Develop Microsimulation Model CONSULTANT will develop AM and PM peak hour SimTraffic models for the study area in order to perform the existing conditions analysis and, ultimately, for the future year analyses. The SimTraffic model will include approximately seven (7) existing intersections along Woodside Road / Seaport Avenue between Blomquist Street and Middlefield Avenue. Six (6) of the intersections are signalized and one location is stop sign controlled (Lyngso access). The existing condition traffic models will be calibrated based on the existing traffic counts, estimated demand volume (based on existing queuing), field observations, and travel time runs. The other five study intersections will be evaluated independently using the Synchro software since congestion at adjacent intersection is not a significant problem for these locations. Subtask 3.2.4-Operations Analysis CONSULTANT will analyze the AM and PM peak hour traffic conditions for all 12 study intersections. The measures of effectiveness evaluated for the 5 isolated intersections will include average vehicle delay, level of services and queuing for the isolated intersections. For the intersections along the Woodside corridor, the measures of effectiveness drawn from the SimTraffic model for the AM and PM peak hours will include: average vehicle delay, level of service, percent of vehicles (demand) served, and vehicle queuing. Additional measure may be reported if requested by the PDT or Caltrans functional units. CONSULTANT will utilize the FREQ model to present the following measures of effectiveness for the AM and PM peak hours: vehicle density, level of services, travel time, travel speed, bottlenecks, and queuing on the mainline and on-ramps. Additional performance measures may be presented based on any requests made by Caltrans on the methodologies memorandum in Task 3.1. Crash data will be used to document the existing conditions at the study intersections. The crash data analysis will summarize performance measures including: total number of accidents, accident rates, severity of accidents, and types of accidents. The crash data analysis will include an assessment of the measures to determine if there are particular accident types that occur within the interchange that could be reduced as a part of the interchange modifications. Subtask 3.2.S-Administrative Draft Existing Conditions Memorandum CONSULTANT will prepare an Administrative Draft Existing Conditions Memorandum that documents the analysis described in Task 3.2.4. The draft document will be submitted to the CITY and PDT for review and comment prior to being widely circulated to all the Caltrans functional units. Subtask 3.2.6-Draft Existing Conditions Memorandum CONSULTANT will review comments on the Administrative Draft memorandum and submit a Draft Existing Conditions memarandum to Caltrans for review and comment. CONSULTANT will prepare a response to the Caltrans comments and update the existing conditions memorandum. The information contained in this document will be included in the Traffic Operations Analysis Report. A17Y/AGR/2013.164/URS PROFESSIONAL SERVICES AGR REV:10-15-13 VR Page 25 of 78
