This peer review was supported by the Travel Model Improvement Program (TMIP), sponsored by FHWA. TMIP sponsors peer reviews in order that planning agencies can receive guidance from and ask questions of officials from other planning agencies across the nation. The peer review process is specifically aimed at providing feedback to agencies on travel modeling endeavors.
The primary objective of the PSRC peer review was for PSRC to receive guidance on transitioning from their aggregate, trip-based travel model to their activity-based model, which currently is operational, but not used as the official model for the agency. Further, PSRC received feedback on several other modeling tools (e.g., visualization) and future directions (e.g., dynamic traffic assignment).
The peer review panel convened for one day and one-half day (November 5, 2015 to November 6, 2015). During that time, PSRC presented background information and asked for guidance in specific areas of their modeling practices, and the panel discussed these items and offered a series of formal recommendations to PSRC.
