TRAFFIC INFORMATION PROCESSING DEVICE AND PROCESSING METHOD AND PROGRAM THEREFOR

摘要

A traffic information processing device that calculates the estimated position of a vehicle, and determines whether or not the vehicle has transited a passage point. The traffic information processing device also determines whether the passage point is a defined point or an undefined point. If the determination is that the vehicle is at a defined point, transit information indicating the transiting of the passage point is output on a display unit (40) at an estimated transit time for the calculated passage point.
