The Michigan Department of Transportation (MDOT) wanted to develop a dynamic traffic assignment (DTA) model to assist the Department and the community on making the appropriate decision for a major freeway rehabilitation project in the Metro Detroit area. The I-96 corridor is a major freeway corridor, which carries freight flows and is a major commute route in the Detroit area. The I-96 corridor requires a total reconstruction of approximately six miles of freeway with major interchanges. MDOT developed a separate RFP to develop the DTA model. The DTA model was developed from the MPO model. Key peak periods were validated and calibrated to assess the impacts that various construction scenarios would have on the commute corridor. An additional RFP for the freeway construction plans was developed by the MDOT to use the DTA model to assist in the decision-making process of various construction staging scenarios. Over 15 scenarios were tested and compared to the base condition. These scenarios included total closure and maintaining various lanes of travel by direction. The DTA model was overlaid with the various scenarios and used in the public involvement process to aid in decision making. A hot spot analysis was also performed using the DTA model to test various improvements that could be made to the region that would ease the construction of the freeway when it is under construction. The presentation will cover the development of the DTA model, the alternatives analysis and comparisons, the use of the DTA in the public involvement process, the use of the DTA for the hot spot analysis, and the community and agency view of DTA.
