1.   Use of Dynamic Traffic Assignment in FSUTMS in Support of Transportation Planning in Florida FDOT Research #BDK80 Task Work Order No June

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
