Abstract:
A toll collection system includes: a vehicle detector which detects entry of a vehicle to the lane; a vehicle type identification unit which identifies the vehicle type of the vehicle at a stage before the vehicle is detected by the vehicle detector; and a position measurement unit which measures, on the basis of a position measurement signal obtained by receiving, through a predetermined position measurement antenna, radio waves transmitted by the on-board unit after the vehicle is detected by the vehicle detector, the position of the on-board unit which has transmitted the radio waves. The position measurement unit is configured to measure the position of the on-board unit on the basis of an angle of arrival of the radio waves measured on the basis of the position measurement signal, and an installation height of the on-board unit estimated from a vehicle type identification result of the vehicle.
