Title:

Comparing Aggregate Trip-Based and Disaggregate Tour-Based Travel Demand Models: Highway Results

Abstract:

In 2001, the Mid-Ohio Regional Planning Commission (MORPC) contracted to develop a disaggregate tour-based travel demand forecasting model for the Columbus, Ohio area. As the Ohio Department of Transportation (ODOT) coordinates modeling activities throughout the state, and as the Cleveland (NOACA), Cincinnati (OKI) and Dayton (MVRPC) MPO models will be updated to a new 2010 base year in the near future, ODOT decided to vet the new tour model against a trip model using before and after studies to determine if the model structure impacts model results. If the tour-based structure impacts planning level traffic results favorably, then the added expenditure (in both time and cost) to upgrade the NOACA and OKI/MVRPC models to a tour-based structure would be warranted more than just from the flexibility in conducting additional types of analyses. Four study areas were chosen for analysis: a new freeway interchange with new development, new development without highway improvements, innerbelt completion and a control area. Assignments are comparable between the two models for all areas, and both models perform equally well when used for the generation of design traffic. Highway assignments are compared. In the Columbus, Ohio region, the type of model does not appear to impact the development of design traffic forecasts, and any new model structure would be chosen solely upon sensitivity to policy analyses that are of interest to the region.
