A simulation study in the Washington, DC area found that 40 percent of travelers who use pre-trip traveler information would save $60.00 or more per year as a result of fewer early and late arrivals.
The simulation results were dependent on the estimated accuracy of archived real-time travel time data used to establish the baseline for ATIS non-user travel, and the ATIS non-user tolerance for late arrivals.
A dollar valued disutility framework was used to determine the cost value of delay, early arrivals, and late arrivals. By applying this utility function to all trips, it was found that approximately 40 percent of all ATIS users achieved an individual net positive benefit of approximately $60.00 or more per year.
