FSUTMS training is a major activity of the Systems Planning Office of FDOT. The training aims to establish and maintain quality assurance for consistent statewide modeling standards and provide up-to-date information on recent model enhancements. FSUTMS training workshops have been conducted mainly with a lead instructor in a computer laboratory setting at selected locations. The costs of conducting and attending these workshop are sizable for both FDOT and the participants. This inevitably creates a limiting effect on the workshop availability and participation. The objective of this project is to develop an online alternative of the live version of the FSUTMS Comprehensive Modeling Workshop.

Intelligent Transportation Systems (ITS) planning requires that use of tools to assess the performance of ITS deployment alternatives relative to each ot her and to other types of transportation system improvement alternatives. This research project investigates the development of tools and procedures to perform sketch-planning evaluation of the costs and benefits of ITS alternatives within the Florida Standard Urban Transportation Model Structure (FSUTMS) modeling environment.

This research report describes a standalone master network system that was developed to work with Cube Voyager- the modeling engine of the Florida Standard Urban Transportation Model Structure. Stored in ESRI's Personal Geodatabase format, the master network database structure was designed to minimize data storage space, extract efficient networks with consolidated links, support open and unlimited data attributes, and implement both forward and backward network propagations.

Over the past several years, there has been a growing interest in the development of disaggregate (individual- or household-level) travel-demand models. In the case of Florida, this is evident from their efforts to incorporate socio-demographic variables within the FSUTMS structure via "lifestyle" trip production models. However, the lack of a systematic procedure to forecast the household characteristics required by such disaggregate travel-demand models has been recognized as an important impediment to furthering these efforts for state-wide adoption. In this context, the broad focus of this research is to contribute towards the devleopment of methodology for comprehensively forecasting all traveler characteristcs required as inputs to travel-demand forecasting models.

Transportation models are used to forecast travel behavior and patterns, and thus to aid decision makers in developing transportation plans and making investments. Quantity and quality of data are critical to effective modeling. However, data accessibility has been a major and persisting challenge facing transportation modelers. Indeed, it is not unusual for data preparation to take up over 70% of the total modeling effort.

Advances in computer hardware and software have led to an increasing level of sophistication in travel demand forecasting. Many researchers have taken advantage of the improved computing power to refine travel demand models. Traditional travel demand models rarely consider intersection delays when estimating travel time. This is because modeling intersection delays is challenging due to the complexity in roadway geometry, signal plans, and vehicle movements.

Freight transportation is both multimodal and intermodal in nature, involving highways, railways, waterways, air transportaiton, terminals, and intermodal transfers. Multimodal and intermodal orientation holds major promise in significantly improving freight transportation efficiency. Wise investment in the development of multimodal and intermodal infrastructure can effectively remove major bottlenecks on freight networks, expand shipping alternatives, reduce congestion and environmental impact, and improve safety and efficiency of the entire transportation system.

The Florida Standard Urban Transportation Modeling Structure (FSUTMS) is a computerized model package developed by the Florida Department of Transportation (FDOT) for planning and analysis of transportation systems. It has been used by all 26 Metropolitan Planning Organizations, FDOT Districts and other planning agencies in Florida. Currently FSUTMS models daily travel demand and then produces estimates of peak volumes through a simple post-processing routine. However, there are pressing needs to address planning issues and answer questions that are time-of-day (TOD) related. The daily-basis modeling framework is not competent for those tasks.
