Dowling Associates, Inc. Transportation Engineering Planning Research Education SCOPE OF WORK ATTACHMENT 3 This section presents an outline of our proposed work plan for technical and professional services pertaining to the refinement, validation, application and training for the transportation model. We have developed a simple approach based on our many years of modeling experience, and believe that this plan will meet all of the City's goals for this study. Please note that while all of the work scope items identified in the City's RFP are included herein, they may have been reorganized to tit our methodology and approach. In summary, the Dowling Associates team will act as on -call consultants with the goal of providing high quality, cost effective responses to request for technical modeling support. TASK 1 MODEL UPDATE 1.1 KICK -OFF MEETING Dowling Associates will consult with City staff to discuss model update issues and then will prepare a draft model methodology working paper for review by the City. The working paper will address the following issues: Recommended changes to the model road network, inside and outside the City of Pleasanton. Recommended changes to the zone system and zone connectors. Land use categories and trip generation rates, most likely based on ITL Trip Generation (convert to variable equations vs. single average rates). Required level of interface with the City of Livermore, City of Dublin, Alameda County Congestion Management Agency (CMA), Contra Costa Transportation Authority (CCTA), and the MCC regional travel demand models (e.g., where will Livermore and Dublin trips come from) Procedure for analysis of non -auto and transit modes (e.g., most likely a factoring process based on origin destination data by travel mode from the MTC model). Appropriate forecast years for approved (2015?) and buildout (2035 Peak spreading needs. Procedure for development of intersection volumes (counts, Furness adjustments. etc.). Model validation criteria and screenlines, including commute patterns and cut- through traffic. Advantages and disadvantages of using a base year matrix estimation process that fits trips to traffic counts The model methodology working paper and associated maps will be modified in response to comments by City staff. 1.2 COLLECTION AND REVIEW OF EXISTING DATA Current Documents Dowling Associates will work with City staff to ensure that we have knowledge of any documents or studies occurring in the Tri- Valley region which may provide valuable information for the 2009 model update process. Dowling Associates will summarize assumptions and identify any conflicting information. City of Pleasanton 2 2009 Traffic Model Update May 13, 2009
