The Florida Department of Transportation Turnpike Enterprise's recent toll mode-choice model development activities are described. Because the simple toll travel forecasting analysis methods used were not adequate for reliably addressing contemporary toll study issues, there was a need for toll modeling innovations that address trip makers' toll route decisions as a mode-choice step sensitive to changes in service levels by time of day, trip purpose, and socioeconomic attributes. Innovations developed for Florida's turnpike began with data-collection efforts and toll model development for the Central Florida (Orlando) region. This represents the next generation of modeling system. Similar efforts are under way for the Miami-Fort Lauderdale area. The Orlando region toll mode-choice model, which is in its final validation phase, includes a statistically estimated nested mode-choice modeling system with a discrete choice for toll travel. The models were developed for a combination of four periods and four trip purposes, including visitor trips. Other key features are (a) a pre-mode-choice time-of-day process; (b) a generalized cost-assignment procedure that uses travel time and costs by time of day (rather than travel time alone); (c) production of zone-to-zone travel time and costs consistent with travel paths; and (d) a feedback loop process that uses an iterative successive averaging procedure to estimate travel times.
