Abstract:No standard methodology exists in the U.S. for estimating trip generation that takes into account the smart growth characteristics of a land use development project. As a first step toward developing such a methodology, this report assesses the available alternatives to the traditional ITE Trip Generation methodology. We identified eight available methods. For five of these methods, we completed a two-part assessment. The first part was to evaluate the methods against a variety of operational criteria developed through discussions with a panel of transportation practitioners. The second part was to test the accuracy of the methods by comparing the predictions of the various methods against available traffic counts and other data at 22 California sites that have at least some characteristics of smart growth.
