Travel time prediction method from toll collection system data based on deterministic queueing theory.

This study proposes a method for predicting near future travel time of each freeway section between adjacent interchanges from toll collection system data. Since the times a vehicle passes ramps are recorded in the toll collection system data, its travel time between on and off ramps is directly observed. Based on the deterministic queueing theory, the hypothetical cumulative trips for each section are constructed from the travel time without traffic counter data. Near future travel time is then predicted by extrapolating the hypothetical curves. The method has been verified by actual data and reasonable travel time has been predicted.
