VMT OPTION 2-DEVELOP SUBAREA MODEL As an alternative approach,Fehr&Peers can modify the OPTIONAL TASKS Alameda CTC travel demand model to better reflect the City of Pleasanton,including splitting Travel Analysis Q The extents of the current model are not sufficient to Zones,providing additional roadway network detail, adequately forecast vehicle miles of travel(VMT),which and modifying land uses.The Alameda CTC model has may become an important travel metric under the more functionality than the City of Pleasanton model, Ei updated CEQA guidelines being prepared to implement including the ability to develop daily and peak period Senate Bill 743.We propose two approaches as optional forecasts(not just peak hour),as well as calculate vehicle ET tasks that would permit forecasting of VMT consistent miles of travel.The downside to the added functionality with other regional plans. is an increased model run time,and limited control over til some of the model inputs.We would be pleased to VMT OPTION 1 -MINOR PIVOT FROM ALAMEDA CTC provide a more detailed scope of work for this option if ® MODEL requested.
