SUNOL BOULEVARD/I-680 IMPROVEMENTS PA&FD d) Riddell Street/Sunol Boulevard e) Arlington Drive/Sunol Boulevard 4. The four on- and off-ramps at the I-680/Sunol Boulevard interchange The following tools will be used to conduct the forecast and operation work: 1. Validated Year 2018 Alameda CTC Travel Demand Model for forecasting with support from the Dublin,Pleasanton and Livermore travel demand models 2.VISSIM software for freeway, ramp and local street analysis (Fehr&Peers will use the model developed for the I-680 SR 84 to Alcosta Boulevard Express Lanes project as the basis for this study). Based on existing mainline congestion data (as summarized in the 1-680 Express Lanes project documentation), existing congestion along southbound I-680 occurs between 6:00 AM and 10:00 AM. Northbound I-680 is congested between 5:00 PM and 7:00 PM. As noted in the Draft I-680 Express Lanes project TOAR, congestion is expected to increase in the future.Based on discussions with Caltrans on the I-680 Express Lanes project,there is a desire to more comprehensively capture the project's benefits. Therefore, the following scope of work assumes the analysis periods are 5:00 AM to 10:00 AM and 3:00 PM to 8:00 PM, which would cover the Year 2045 congestion projected for the I-680 corridor in the study area. Additionally, the following scope of work assumes that the opening year of the project is Year 2025 and the design year is Year 2045 (generally matching the horizon years of the I-680 Express Lanes project). Subtask 2.1 Existing Conditions. 2.1.1 Fehr & Peers will document existing transportation conditions to support the Project. This information will be used as the basis for subsequent traffic forecasting and traffic operations tasks. Prior to beginning this work,Fehr&Peers will prepare the Traffic Methodology Memorandum that describes the study area,time periods to be evaluated,extent of data collection,and the analytic tools to be used. Study Approach and Methodology. In consultation with Pleasanton and Caltrans, Fehr & Peers will confirm the traffic operational analysis and forecasting methodology. This will include confirming the specific scope of the analysis, and the tools or models to be used. With respect to the overall analysis methodology the specific analysis processes and procedures to be addressed in this subtask include: establish a data collection plan; confirm horizon years (opening year and 20-year); define future year baseline network assumptions; confirm analysis network and boundaries for operational analysis modeling; confirm forecast modeling tool (for scoping assumed to be Alameda CTC travel demand model); confirm analysis methodology/tools for freeway and local highway corridors; confirm operational model calibration/ validation requirements; and review Measures of Effectiveness (MOEs). Fehr & Peers will participate in a kickoff meeting with the project team and Caltrans as part of this task. 2.1.2 Data Collection. The City of Pleasanton and other agencies have extensive data collected for previous studies within the study area. Caltrans also requires that data older than two years be validated against newer data before it can be used.Furthermore,data should be collected to match the study periods. Our previous work in the corridor suggests that existing April 10,2020 5
