Expanding the Capability of the Statewide Travel Demand Model Using Dynamic Traffic Assignment

A relatively recent modeling innovation known as dynamic traffic assignment (DTA) is designed to represent fluctuating traffic volumes and long trips on complex networks over the course of a single day. Integrating an optional DTA step into existing traffic modeling would improve the model’s accuracy, flexibility, and versatility, thereby enhancing ADOT’s ability to evaluate complex modernization projects—such as traffic interchange reconfiguration, intelligent transportation systems, and other traffic operations enhancements—and model traffic congestion and freight movement more accurately than is currently possible. The proposed study would build on the results of ADOT's SPR-768 Dynamic Traffic Assignment: Assessing Its Value as a Planning Support Tool in Arizona.
