BACKGROUND <br /> The Pleasanton Traffic Model is comprised of two computer traffic forecasting programs <br /> which contain specific information regarding Pleasanton's land use and the City's street <br /> network and signal operations to provide a projection of future traffic conditions. <br /> Pleasanton has relied on model projections since the 1980s. <br /> The traffic model has been refined and updated on a regular basis to account for changes <br /> in land uses, roadways and traffic volumes. In addition to these standard updates, the <br /> model has incorporated school zone specific trip assignment, peak hour spreading,.ramp <br /> metering and cut-through traffic data. <br /> With this model update, the land use changes, roadway network changes and new traffic <br /> volumes will again be updated. In addition to these standard updates, the traffic model <br /> will include an update to the cut through traffic assumptions. With the increased <br /> congestion along 580 and 680, cut through patterns and volumes have changed and an <br /> update is necessary to capture these changes. The update will also create a "vehicle <br /> miles traveled" component that may be necessary in future CEQA documentation. <br /> DISCUSSION <br /> The cost of the standard update to the traffic model is $99,500. The optional task of <br /> creating a vehicle miles traveled element to the model and updated cut through data will <br /> be added to the base cost for a total model update cost of$126,800. <br /> In addition to the model update, a new baseline report will analyze all 114 traffic signals <br /> under existing conditions, existing + approved and General Plan Buildout. In addition to <br /> analyzing the Level of Service (LOS) at all 114 existing traffic signals, the report will <br /> identify future improvements to be included in the development fee update. The report <br /> will summarize the last three years of collision data as well as include a new metric that <br /> quantifies existing and projected queue lengths, which will be used to develop circulation <br /> element improvements that are not captured when looking at LOS. All of these elements <br /> will be used to identify future transportation improvement needs. The cost of this report <br /> is $128,400. The total contract amount for these two elements is $255,200. <br /> The recommended contract amount is a not to exceed amount of$275,000. The $19,800 <br /> difference will be used to facilitate future traffic model runs needed to evaluate <br /> development proposals, which are estimated to cost $3,900 per project. <br /> City staff advertised a Request for Proposal for the Traffic Model Update in July of 2015. <br /> Staff received three proposals from qualified consultants: TJKM, Fehr and Peers and <br /> Kittelson Associates. Fehr and Peers has worked with the City of Pleasanton as an on <br /> call transportation consultant since 2006. Although Fehr and Peers has not maintained <br /> the Model for the City in the past, their modeling references have been contacted and all <br /> provided favorable opinions and recommendations. Their past performance on <br /> transportation projects has been excellent. <br /> Page 2 of 3 <br />
