PASSAGE DETECTION SYSTEM, PASSAGE DETECTION METHOD, PASSAGE DETECTION DEVICE, PROGRAM, AND RECORDING MEDIUM

摘要

This passage detection system is provided with: a positioning device (130) which employs both radio navigation and autonomous navigation to determine the position thereof; and a passage detection device (110) which, in cases when a vehicle has passed a prescribed position, detects that the vehicle has passed the prescribed position. The passage detection device (110) is provided with: a position specification unit which, on the basis of a travel state of the vehicle and pre-prepared systematic error information related to systematic error in positioning results from the positioning device (130), corrects a positioning result from the positioning device (130), and specifies a position of the vehicle; and a passage determination unit which determines whether the vehicle has passed the prescribed position on the basis of the change over time in the position specified by the position specification unit.
