Review of TPB Travel Modeling Procedures
It is generally considered best practice for an MPO to get an external review of its travel demand modeling process on a regular, on-going basis. In 2003, TPB staff chose to conduct a review of the modeling procedures using a panel from the Transportation Research Board (TRB). In more recent years, TPB staff has hired a consultant to provide that review. Both efforts are described below.
Transportation Research Board (TRB) Review
At its April 17, 2002 meeting, the TPB approved a process for conducting a review of the region's travel modeling procedures. The process called for the TPB to engage a respected non-partisan organization, such as the Transportation Research Board (TRB), to appoint the members of the peer review panel and oversee the review process. A request was formally made to the TRB on May 8, 2002 in a letter from then TPB Chair, Phil Mendelson. The TRB accepted this task and began its analysis of the TPB modeling procedure in January 2003. On September 8, 2003 the TRB submitted its first letter report and on May 10, 2004 the TRB concluded its analysis with the submission to TPB of its second and final letter report. TPB staff provided detailed comments on each of the TRB reports in letters of September 8, 2003 and May 13, 2004 respectively.
Scan of Best Practices in Travel Demand Forecasting
Beginning in FY 2006, the TPB has had a task-order consulting contract to scan the best practices in travel demand forecasting across the U.S. The scope of work for this project includes three components:
For fiscal years 2006-2008, the contract was awarded to Vanasse Hangen Brustlin, Inc. (VHB). For fiscal years 2009-2011, the contract was awarded to Cambridge Systematics, Inc. In FY 2012, the contract was awarded to AECOM. The following documents have been produced:
