DUBLIN, CITY OF 2001 - Laserfiche WebLink

of service for all intersections. Coordinate this traffic analysis with Caltrans to ensure that the above work elements are acceptable to them and to the City. Task 4a Analyze freeway mainline merge /diverge, or weaving level of service to evaluate alternative lane configuration on freeway mainline and ramp junctions. Task 4b Perform ramp -end intersection level of service analysis to determine the intersection lane configuration at Fallon Road and El Charro Road Task 4c Perform signal warrant analysis Task 4d Perform queuing analysis to determine the storage lengths for the turning movements at intersections Task 4e Address ramp metering, 13OV lane consideration, and mainline operations Task 5. Prepare Draft Traffic Operation Report (TJKM) Prepare and submit to the cities and Caltrans, a Draft Traffic Operations Analysis Report for review. Task 6. Validation of Traffic Analysis (CCS) Review Draft Traffic Operation Report, validates assumptions and traffic operations analyses. Task 7. Select Link Analyses for Cost Sharing (Dowling) For each of the two sets of model runs (with and without Jack London Extension), a select link analysis will be prepared for the AM and PM peak hours that will identify the city of origin and city of destination for the traffic using the I- 580/Fallon Interchange on- ramps, off ramps, and the bridge over the freeway (7 links). Any vehicle trip using one or more of these links will be added to the city-by -city OD table for the entire interchange. The single table will then be used to compute the percentage of trips by city for each peak hour. The city-by -city OD table will include Livermore, Pleasanton, Dublin, Unincorporated Alameda County, and others. Task 8. Prepare Final Traffic Operation Report (TJKM) Upon receiving comments from the cities and Caltrans, prepare and submit a Final Traffic Operations Analysis Report to the cities and Caltrans. PREPARE GEOMETRIC APPROVAL DRAWINGS (GAD) AND ENVIRONMENTAL RE- EVALUATION Task 1. Prepare Draft Revised GAD including Proposed R/W (CCS) Based on the Draft Traffic Operation Report on lane assignments, turning movements, queue lengths, etc., the GAD as submitted to Caltrans in May, 2000 will be updated. The updated GAD will include additional alignments, if any; revised typical cross sections, profiles, and layouts. Any necessary revision to the existing R/W will also be investigated. In addition, revisions to the 2025 traffic volume will be checked against the "plan line for ultimate geometry". Task 2. Environmental Re- evaluation (Powers, CCS) The revised Year 2015 geometrics will be re- evaluated against the existing environmental document. Any issue that is not consistent with the existing findings or requires additional studies will be identified. Task 3. Evaluate Construction Phasing (CCS) The proposed Year 2015 geometrics will be compared with the "plan line for ultimate geometry" for determination of feasibility and cost effectiveness 2 11/27/01
