EN-ROUTE UPDATING METHODOLOGY OF TRAVEL TIME PREDICTION USING ACCUMULATED PROBE-CAR DATA
2004
Probe-car data include the information about the trajectory of speeds driver have experienced while passing through arbitrary selected sections. This paper discusses the methods of en-route updating travel time prediction, making effective use of probe-car data. Several methods suggested in this paper, which are en-route updating methods using both accumulated probe-car data and driver-experienced data, can predict travel time more accurately than methods that do not use both data in most cases.
