This report summarizes the results of a peer review of the VTrans statewide travel model with a focus on recommendations for future model enhancements. The peer review was supported by the Travel Model Improvement Program (TMIP), which is sponsored by FHWA. The peer review of a travel model can serve multiple purposes, including identification of model areas for improvement, recommendations for model enhancements, and guidance on model applications. Given the increasing complexities of travel demand forecasting practice and the growing demands by decision-makers for information about policy alternatives, it is essential that travel forecasting practitioners have the opportunity to share experiences and insights. The TMIP peer review program provides a forum for this knowledge exchange.
VTrans's overall goal for model improvement and motivation for seeking a TMIP peer review was to continuously maintain and apply a model representative of the state of the practice in travel forecasting that equips the agency with the support needed for informed decision making throughout the state. The peer review was conducted in four two-hour phone/web-based meetings: two technical background meetings including TMIP moderators, VTrans and associated staff, and peer review panelists; one meeting between the panelists and TMIP moderators to discuss potential recommendations; and one final meeting involving all parties to present these recommendations to VTrans. The results of each of these discussions and recommendations from the panel are presented in this report.
