Use of Dynamic Traffic Assignment in FSUTMS in Support of Transportation Planning in Florida
A number of tools have been developed to perform DTA. These tools vary in their capabilities and in the underlying models and procedures used in these tools. Some of these tools are open source allowing further improvements and customization of these tools to specific state needs. The Florida Modeling Task Force (MTF) with input from the transportation planning community in Florida has identified the incorporation of dynamic traffic assignment in the FSUTMS (the demand modeling environment in Florida), as a high priority required improvement. However, there are many issues that need to be addressed for the successful and optimal implementation of DTA in the FSUTMS. This project is developing a dynamic traffic assignment process within the FSUTMS environment that will allow the modelers to utilize this process in all or some of the demand forecasting steps. The objectives of this project are:
- Reviewing the capabilities of existing DTA tools and associated models
- Identifying the requirements of Florida demand modeling with respect to DTA
- Identifying the ability of existing DTA tools to meet the Florida demand modeling requirements
- Identifying the data requirements and the associated resources and procedures needed to estimate dynamic short period interval O-D matrices and to develop and calibrate DTA applications.
- Developing tools to support effective and efficient use of the DTA within the FSUTMS
- Documenting the project effort, results, and conclusion
