Collar County Travel Demand Model

Collar Counties, Minnesota

SRF was retained by the Minnesota Department of Transportation to develop a travel demand model that covers the twelve counties bordering the Twin Cities (“collar counties”) and is compatible with the existing Metropolitan Council regional model. SRF performed an extensive external survey, using roadside and mailback surveys at twelve entry/exit points to the region. Additional data was extracted from the existing household interview survey to help develop statistically meaningful calibration parameters. SRF developed a transportation network for the collar county area, participated in the development of new model parameters, and validated the new model over the entire area. The model will be used for better understanding the increasingly important flow of traffic into and out of the Twin Cities region.
