Subtask 3.3.3—Manually Adjust Model Results Depending on the alternative, CONSULTANT may need to manually adjust the model results to test subtle variations between alternatives. CONSULTANT will minimize the number of model runs by using these manual adjustments. This approach may reduce the overall modeling effort and may be beneficial in gaining acceptance from the Long Range Planning Forecast Unit since the demand volumes will be more consistent for alternatives with minor changes. Subtask 3.3.4-Administrative Draft Travel Demand Forecasting Memorandum Once the project alternatives are defined, CONSULTANT will complete a draft Travel Demand Forecasting memorandum documenting the forecasts for the No Project and the two alternatives to be studied in the Traffic Operations Analysis Report. The draft memorandum will be submitted to the CITY and PDT for review and comment. Subtask 3.3.5-Draft Travel Demand Forecasting Memorandum CONSULTANT will finalize the draft Travel Demand Forecasting memorandum based on comments from the City and PDT. The draft memorandum will be submitted to Caltrans for review and comment from the functional units. Once the comments are received, CONSULTANT will meet with the reviewers if there are comments that need clarification and to review the proposed changes to the analysis. Subtask 3.3.6-Final Travel Demand Forecasting Memorandum CONSULTANT will finalize the Travel Demand Forecasting Memorandum, incorporating changes based on Caltrans comments, and submit for approval. Meeting with Caltrans reviewers in Task 33.5 is designed to streamline the acceptance of the document. Task 3.4-Alternative Analysis CONSULTANT will participate in the development of alternative designs far the interchange. CONSULTANT will participate in working sessions where the interchange design concepts are developed. CONSULTANT will provide VTA network changes as input to the model runs. As mentioned previously, five alternatives will be considered in the alternatives analysis; however, it may not be necessary to run an individual model for each alternative. The alternatives that will require modeling are those that significantly change the ramp connections, such as the split diamond and flyover designs. This task ultimately includes the testing of two preferred alternatives using the AM and PM peak hour volumes far the design year using the calibrated Synchro/SimTraffic model in Task 3.2.3. Subtask 3.4.1 -Alternatives Evaluation CONSULTANT will contribute in the development and evaluation of potential design alternatives by participating in the working sessions. At a working session, CONSULTANT will provide input related to the general operational advantages or disadvantages of each design concept. This input will be informed by the existing conditions analysis prepared for the study ATTY/AGR/2013.164/URS PROFESSIONAL SERVICES AGR REV:10-15-13 VR Page 27 of 78
