A system and method for predicting the location of a vehicle in an electronic toll collection system employing a wide area communication protocol. The vehicle includes a transponder that sends reports regarding the position of the vehicle and the time at which the position was determined. The system includes a vehicle position predictor for estimating the future position of the vehicle within a roadway based on two or more reports of past positions and the times at which they were recorded. Speed data or other data impacting likely future position may also be reported and factored into the estimate. The estimate of future position may be used in connection with triggering enforcement measures, timing a toll transaction, integrating wide area toll communications into a legacy toll transaction system, or for other applications.
