Abstract Transportation planning is based on the physical structure of roadway networks and, less tangibly, on choices individuals make about their transportation needs and use of the roads. For a task this complex, computer modeling is essential. In Florida, transportation planning often uses the Florida Standard Urban Transportation Model Structure (FSUTMS) to provide a consistency of data and approach. Currently, demand forecasting in FSUTMS uses static traffic assignment, in which properties of transportation networks, such as travel times and flow rates, are constant over time and drivers are described homogeneously. Dynamic traffic assignment (DTA) could greatly advance FSUTMS by allowing scenarios in which transportation measures vary with time and drivers are treated as individuals, permitting new levels of detail and precision, thus supporting better demand and performance forecasting.
