Create a tool the city can use with confidence to making multiple stops within a given development area. U help make critical decisions about infrastructure Our experience Is that use of ITE trip generation rates needs and prioritization. tends to overstate traffic volumes in a city as a whole. 2. Create a model that is simple enough for staff and We conducted several tests to determine the implication decision-makers to understand the relationship of adjusting trip rates in the Livermore model (which is between Inputs and outputs,while at the same time similar to Pleasanton s)on validation at the roadway being detailed enough to capture the major travel segment level.Using this approach while remaining patterns through the City and how they reflect consistent with ITE's Trip Generation Handbook,the various internal and external influences. model validation results improved substantially and the 3. Create a thoroughly documented model so that model volumes(at the intersection level)were much future users can easily understand how to use it,and closer to the actual counts,thus requiring fewer manual so the major assumptions and data inputs can be adjustments on individual roadway links.We were able referenced for future use. to further improve validation by making adjustments for areas of town with high vacancy rates. As City staff is aware,the land use and transportation For Pleasanton,we recommend starting with updated planning process includes both technical and policy trip generation rates from the 9th Edition of the ITE Trip considerations,and the outcomes of the process can be Generation Manual,with adjustments following standard controversial.Therefore,it Is important that a travel modeling procedures that will be identified during the model be developed using the best data available,that model validation task.Alternative approaches,such as �] the results can be replicated by others,and that its procedures and validation results meet or exceed person trip generation rates that allow for the option of including a better mode choice component in the industry standards.This allows the model's outputs and model,can also be discussed. resulting recommendations to be defended if there is a legal or political challenge. Cut-through Traffic Pleasanton experiences regional cut-through traffic Fehr&Peers encourages a highly collaborative between 1-580 and 1-680,due to congestion on those environment,both internally and externally.We will freeways and the availability of alternate routes through actively seek input from City staff throughout the model the City.The Pleasanton model reflects this cut-through development and reporting process;a model is only as traffic based on a license plate survey conducted in good as the data that goes into it,and local staff have 2009/2010 and data from the Alameda CTC model.We expert knowledge of their local communities. will review the recent traffic counts as well as the E2 KEY ISSUES available cut-through data.We have also included an Based on our experience using the City of Pleasanton optional task to update the cut through traffic model,there are several areas in which the Pleasanton percentages by obtaining cell phone and US data to model can be improved as part of this update. track regional traffic moving through the City.This data could be used to update the cut-through percentages Trip Generation Rates for specific routes or for all potential cut-through routes.
