Abstract
A recording unit records an installation position of a ground installation object and an installation identifier of the ground installation object for each of a plurality of the ground installation objects installed beside a track on which a vehicle of a track transport system mounted with an external sensor travels; an installation object recognition unit specifies the installation identifier from external sensor information including information detected by the external sensor and recognizes the ground installation object corresponding to the installation identifier by referring to the recording unit; and a detection distance calculation unit calculates a detection distance of the external sensor. The detection distance calculation unit calculates the detection distance of the external sensor from a self-position of the vehicle at which the ground installation object is recognized and the installation position of the ground installation object recognized by the installation object recognition unit.
