  • The last few years have seen tremendous advances in Florida’s efforts towards advancing its travel-demand modeling practice. A vast majority of the efforts focused on the residential trips within a regional context, while other critical “ancillary” components, such as external travel, non-residents/tourist travel, urban goods movements, and special generators such as airports and universities, are not modeled to the same level of detail as the residents’ internal travel.

    With all the efforts in improving the modeling of residential travel demands with the activity-based modeling approach, it is also critical to enhance the forecasting of the ancillary demands so as to improve the overall accuracy of the demand forecasts, as well as to better adapt to the activity-based paradigm.

    In collaboration with Dr. Sivaramakrishnan Srinivasan from University of Florida, the intent of this study is to develop a planning document that will guide the enhancements to be made to FSUTMS from the perspective of modeling the ancillary demands. The major objectives of this research project are:
    • Identify the major ancillary-demand components that are relevant to the different modeling regions of Florida
    • Review current best practices in incorporating ancillary demands within the overall forecasting framework (both Trip-based and Activity-based)
    • Document existing sources of data and future data needs
    • Develop a strategic plan document that will guide the process of enhancing the ancillary demand modeling efforts within FSUTMS
