Report Purpose

This report summarizes a peer review of the CHCNGA-TPO travel demand model and proposed land use model. The peer review was supported by the Travel Model Improvement Program (TMIP), which is sponsored by FHWA. The peer review of travel model and land use models 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 and land use forecasting practices and the growing demands by decision-makers for information about policy alternatives, it is essential that travel demand and land use forecasting practitioners have the opportunity to share experiences and insights. The TMIP-supported peer review provides a forum for this knowledge exchange.

The CHCNGA-TPO has a goal of having an integrated land use and travel demand model that:

The CHCNGA-TPO's motivation for seeking a TMIP peer review was to obtain guidance that would help them in achieving their travel and land use modeling goal. In this context, the CHCNGA-TPO was seeking input on the following:

  1. Establishing the best appropriate design structure for the Travel Demand Model (TDM) and Land Use Model (LUM)
  2. Identifying critical activities and milestones for the TDM update and creation of the LUM
  3. Identifying critical activities and milestones for the interaction between the TDM and the LUM
  4. Evaluating the level of consultant involvement to achieve the scope of work for the TDM and LUM update to ensure calibration to federal standards and optimize technological transfer for the CHCNGA-TPO staff
