FSUTMS models contain reports that modelers can review to assess a model's performance, determine if the model meets validation and calibration standards, and alert issues that should be investigated. This webinar will provide information and present examples from current models.

Everything we do in travel demand modeling (TDM) hinges around trip tables. Where trips are generated and where they are going is crucial since by accumulating those trips on the transportation infrastructure, either transit or highway, we know if there will be enough capacity to handle those trips at the time period that this capacity is needed. This leads us to the variable that explains how far we travel and when, which is the impedance associated with each trip; i.e., the associated time, distance, and/or cost of the chosen route, which TDMs also keep track of using tables or matrices. This webinar describes the issues surrounding the development of trip tables or matrices, sources of data, estimation techniques to fill in the data gaps in O-D matrices, as well as the associated impedance skim tables or matrices.

Did you think that you would get away from travel demand modeling without an understanding of choice modeling? Think again! There is an increased use around Florida and the country of choice modeling applications beyond just travel mode choice including toll route choice, destination choice, and activity based modeling just to mention the most popular ones in transportation planning. This webinar describes the fundamental concepts behind discrete choice theory and transportation modeling applications like destination choice. FDOT developed a pilot model in the Capital Region (Tallahassee, FL) that includes destination choice as the tool for trip distribution, and this portion of the model will be presented as an example.

Friction factors, trip lengths, BPR curves, and speeds are used to calibrate travel demand models. New modelers may not be familiar with these terms and their importance, and seasoned modelers may have forgotten the basics. This webinar will provide information and present examples from current models. Friction Factors, Trip Lengths, BPR Curves, and Speeds:

The relationship between land uses and the transportation system are interrelated and well documented. Accurately representing this relationship in travel demand models enhances the capability of the traffic forecasting process. This webinar will provide a brief overview of some of the land use models currently being utilized with the primary focus being the Florida Land Use Allocation Model (FLUAM). This land use allocation model is being used for statewide applications and can also be used at the regional or county level. The FLUAM process that will be presented includes:

Statewide databases are available to the modeling community that can greatly enhance the quality and accuracy of the components that make up any model. The Florida Department of Transportation (FDOT) maintains some of these databases and purchases other data from vendors. This webinar will explore these statewide databases and show how they can assist in modeling efforts. Topics will include:

Cube version 6 makes it possible to upload your model and data to a hosted, scalable cloud computing environment. This places the model in an arena of essentially unlimited hardware, allowing you to run quickly one or multiple scenarios simultaneously without needing to invest in expensive hardware. In addition to these performance benefits, moving your models to the cloud allows them to be shared between multiple users without needing to make copies of the models and their data. Models in the cloud are accessed through a secure, customizable web interface, making it possible to work from anywhere at any time. This webinar teaches you how to get started using Cube Cloud and how to get the most out of this innovative technology from Citilabs. Topics will include:

Understanding freight movements and modeling the effects of freight investments, such as port expansions, on the transportation system are of great importance given the significant role that freight mobility plays as an economic driver for the state of Florida. FDOT is currently developing new modeling tools that will support freight analysis, including the Florida Multimodal Statewide Freight Model.
This webinar will provide an overview of freight modeling, including freight data and how to work with it, and the various forms of freight model that are in use in the United States. It will be followed by a discussion of the new Florida Multimodal Statewide Freight Model and the regional truck touring models than can be linked to the statewide model.
Topics will include:
