Report Purpose

This report summarizes the results of a peer review of the AMBAG travel demand model. 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 deficiencies, recommendations for model enhancements, and guidance on model applications. Given the increasing complexities of travel demand forecasting practices and the growing demands by decision-makers for information about policy alternatives, it is essential that travel demand forecasting practitioners have the opportunity to share experiences and insights. The TMIP-supported peer review provides a forum for this knowledge exchange.

AMBAG's motivation for seeking a TMIP peer review was to ensure that AMBAG staff, its policy board, regional transportation planning agencies (RTPA) and local jurisdictions have a state-of-the-practice tool to support their land use and transportation planning needs. In this context, AMBAG was seeking input on the following:

  1. Receive external guidance on current model's functionalities
  2. Identify possible model deficiencies
  3. Receive recommendations for AMBAG's Model Improvement Plan (MIP)
  4. Receive experienced advice on model development and applications
  5. Receive expert opinion for agency resource needs, such as surveys/other data requirements, technical assistance, funding recommendations and time frame for model improvements
