SUNOL BOULEVARD/I-680 IMPROVEMENTS <br /> PA&ED <br /> congestion occurs for longer than two hours in the morning and afternoon peak periods. <br /> Fehr & Peers will collect new local street intersection turning movement counts <br /> (including pedestrian, bicycle and heavy truck counts) for the five identified study <br /> intersections. The intersection turning movement counts will be collected for the 5:00 <br /> AM to 10:00 AM and 3:00 PM to 8:00 PM peak periods. The turning movement counts <br /> Demand volumes will be estimated for congested peak periods. <br /> 2.1.3 Data Collection Processing. <br /> Fehr&Peers shall compile the collected data and evaluate for reasonableness. <br /> 2.1.4 Existing Conditions Analysis. <br /> Fehr & Peers, as part of the I-680 Express Lane, developed a micro-simulation model <br /> covering northbound I-680 between SR 237 and Alcosta Boulevard and southbound I-680 <br /> between Alcosta Boulevard and Sheridan Road. This model is being used to deliver the <br /> Traffic Operation Analysis Report (or TOAR) to Alameda CTC for the 1-680 Express <br /> Lanes project and was constructed in a way to facilitate quick testing of project <br /> alternatives. Fehr & Peers will modify the 1-680 Express Lanes micro-simulation model <br /> and update the inputs for use on this project. <br /> Based on the compiled data Fehr&Peers shall prepare the existing conditions technical <br /> analysis including building and executing AM and PM peak period VISSIM micro- <br /> simulation models for 1-680 between 1-580 and Andrade Road and the Sunol Boulevard <br /> corridor between Castlewood Drive and Arlington Drive. The VISSIM models will be <br /> calibrated and validated to existing traffic conditions within Caltrans-accepted tolerances <br /> for traffic operations models. Existing pedestrian, bicycle, and transit facilities will be <br /> qualitatively assessed; these modes will also be incorporated, as appropriate, into the <br /> operations models. In addition, recent mainline, ramp and local street collision data will <br /> be reviewed and summarized in the report. <br /> 2.1.5 Existing Conditions Memo <br /> A draft Existing Conditions Report will be prepared that summarizes the data collection <br /> procedures and results, the field observations, the LOS, speed, density, and queuing <br /> characteristics resulting from the VISSIM analysis, as well as the validation statistics of <br /> the calibrated model. System-wide measures of effectiveness such as vehicle hours of <br /> delay, volume served, and vehicle miles of travel will also be established. The draft <br /> existing conditions report will be submitted for City of Pleasanton and Caltrans review; <br /> based on one round of agency comments the report will be finalized. Comments and <br /> responses will be documented in a comment resolution matrix and any unresolved <br /> comments after the first round of review will be incorporated into the draft TOAR. The <br /> Existing Conditions report will be focused on the mainline and intersection analysis <br /> performed using the VISSIM model. Fehr & Peers will participate in one Traffic Focus <br /> meeting with the project team and Caltrans as part of this task. <br /> Subtask 2.2 Traffic Forecasts—Traffic Forecasting Development <br /> Fehr & Peers will prepare a memorandum comparing the Alameda CTC, Dublin, and <br /> Pleasanton travel demand models and make a recommendation regarding model use for <br /> this study.For scoping and costing purposes,the recommendation is assumed to be to use <br /> the most current available travel demand model from Alameda CTC to establish traffic <br /> Apri110,2020 6 <br />
