摘要

In 2001, the Mid-Ohio Regional Planning Commission (MORPC) contracted to develop a disaggregatetour-based travel demand forecasting model for the Columbus, Ohio area. As the Ohio Department ofTransportation (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 baseyear in the near future, ODOT decided to vet the new tour model against a trip model using before andafter studies to determine if the model structure impacts model results. If the tour-based structure impactsplanning level traffic results favorably, then the added expenditure (in both time and cost) to upgrade theNOACA and OKI/MVRPC models to a tour-based structure would be warranted more than just from theflexibility in conducting additional types of analyses.Four study areas were chosen for analysis: a new freeway interchange with new development, newdevelopment without highway improvements, innerbelt completion and a control area. Assignments arecomparable between the two models for all areas, and both models perform equally well when used forthe 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 designtraffic forecasts, and any new model structure would be chosen solely upon sensitivity to policy analysesthat are of interest to the region.
