  1. Use of Dynamic Traffic Assignment in FSUTMS in Support of Transportation Planning in FloridaFDOT Research #BDK80Task Work Order No. 977-12June 22 2010

  2. Project Goal Implement a dynamic traffic assignment process within the FSUTMS environment

  3. Background (1) MTF with input from the transportation planning community in Florida has identified the incorporation of DTA in the FSUTMS, as a high priority required improvement There are many issues that need to be addressed for the successful and optimal implementation of DTA in the FSUTMS Fright Corridor Management research project will provide valuable input to this project Interaction with the ITS Operation Tool Project

  4. Background (2) DTA technical sub-committee of the MTF model task force Coordination with SHRP2 projects

  5. Project Objectives Review existing DTA capabilities Identify the requirements of Florida demand modeling Identify the ability of DTA tools to meet requirements Identify the data requirements and sources Identify and conduct needed modifications Integrate DTA capabilities within the FSUTMS Develop tools to support use Document the project effort, results, and conclusion

  6. Task 1 DTA Review Review of DTA literature DTA approaches Traffic flow models Modeling capabilities and features Previous applications O-D matrix estimation Data needs Calibration approaches Integration with other environments

  7. Task 2: Requirements Identification Potential for early survey Workshop: In coordination with the DTA sub-committee of the MTF model advancement committee. Review the results from Task 1 Determine the requirements for DTA modeling as part of the travel demand forecasting process in Florida

  8. Task 3: Assessment of Existing Tools Assessment of existing tools and models Ensure that the tools meet the requirements of using DTA as part of Florida demand forecasting modeling processes Assess if the tool performs as expected Bugs, limitation, constraints, unexpected/illogical results, run time, integration problems, technical support

  9. Task 4: Enhancement of Tools Perform the enhancements needed to existing DTA tools to satisfy the Florida modeling requirements Integrate DTA capabilities within the FSUTMS Not all identified required enhancements may be possible Reasons why any requirements are not addressed in this project will be documented

  10. Task 5: DTA Support Tools and data to support use and calibration of DTA Conventional and ITS data will be integrated according to requirement. O-D estimation process DTA and traffic flow model parameter calibration Post processing of data Advanced technology modeling

  11. Potential Process

  12. Task 6: Testing This task will include the testing of the developed DTA environment and tools within the FSUTMS The research team will select a regional FSUTMS demand model in Florida for the testing of the developments. The test will include all components of the developed DTA modeling process including data collection, data processing, trip matrix estimation, model input generation, model execution, calibration support, and output post processing

  13. Task 7: Workshop and Documentation  Final report Training workshop

  14. Project Researchers  Mohammed Hadi Citilabs Halit Ozen Yan Xiao Wei Zhao Shaghayegh Shabanian
