$175,000 is needed to cover the cost of expanding the scope of the original CMA study to include the recommendations of the Tri- Valley city staff sitting on the Technical Advisory Committee (TAC) to enhance the traffic demand and forecasting model and build a traffic operations model for this study to more carefully study impacts to local roadways. The smdy's Policy Advisory Committee (PAC) discussed this recommendation on January 31, 2005. The PAC decided to recommend this approach, and recommends that Pleasanton, Livermore and Dublin share the cost of funding up to $175,000 in excess of the CMA's budget for additional work in this study. BACKGROUND The CMA has begun a study of 1-580, 1-680 and Route 84 corridors (Tri-Valley Triangle Traffic Study) to refine planned improvements and to identify the best sequence to construct these improvements. A goal of the study is to develop consensus on the proposed projects and project sequencing so that projects can move forward with unified local support. The CMA has budgeted $400,000 for this study. The study is expected to take nine to twelve months to complete. The following regional transportation projects are among those being studied: ~,I-580 HOV lanes and auxiliary lanes; eI-680 HOV lanes; eRoute 84 widening; · I-580/I-680 westbound to southbound flyover; · Altamont Pass truck climbing lanes. The final list of projects and combinations to analyze will be determined as part of the study. The study's TAC, consisting of staff from Pleasanton, Livermore, Dublin, Alameda County, Caltrans, ACTIA, Congestion Management Agency and the consultant team, has met several times to refine the consultant's scope of work. The technical work proposed for the study can be broken into the following key elements: 1. Choose and re£me a travel demand forecast'mg model; 2. Choose and develop a traffic operations model; 3. Identify project scopes and combinations to model; 4. Run traffic models and analyze data; SR 05:050 Page 2 of 5
