REQUEST FOR PROPOSALS TRI-VALLEY TP, ANSPORTATION COUNCIL COMBINED STUDY July 1995 Projections) the "Expected Year 2000, and 2010," the "ABAG 2000 and 2010," and their "Recommended 2000 and 2010" The TVTAC will assure that the aggregate population and employment projections meet ABAG totals for the Tri-Valley prior to the consultant loading the traffic model. Any resolution of differences between local jurisdictions -_ "Expected Land Use" and ABAG '94 Land Use Projections shall be the responsibility of Tri-Valley Council and the local jurisdictions. 1.2 VALIDATE THE TRI-VALLEY MODEL The object of this task is to update the validation process to MTC standards. This will entail: 1.2.1 Reevaluate roadway assignments. This task will address the model system trip distribution step, updating homebased work trips to reflect the 1990 census and travel survey data. The consultant should revise the trip distribution procedures, if applicable, for MTC model system consistency. The consultant will revalidate the trip distribution model by modifying friction factors and/or adding area-to-area factors (K-factors) until a good comparison with MTC trips is achieved. Other purposes are assumed to remain from the current model. The targets for consistency with MTC' s estimates will be 5 percent for intracounty and intraTri-Valley trips and 10 percent for other significant district -to-district and county-to- county movements. Description: · Obtain revised trip distribution model formulation (friction factors, etc. ) from MTC and 1990 "observed" trips by trip purpose · Incorporate into Tri-Valley Model · Run Tri -Valley Model trip distribution model and compare results to MTC · Meet once, collectively with MTC, CMA and CCTA to discuss results · Where there are significant differences in results, investigate network revisions, use of K-factors
