Several studies sponsored by the EPA, national organizations, and state and local agencies have been initiated to try to improve transportation modeling. The report documents the results of one of these efforts. The purpose of the work was to produce a list of current shortcomings both in transportation model structure and in the ways transportation models are used, written in large part from the perspective of air quality modelers. The intention has been to provide a document which would be of use to both transportation and air quality modelers. In addition, a list of improvements to either the models or transportation modeling procedures, augmented by sample model runs demonstrating implementation of some of these suggestions, is provided.
