Abstract: A memory stores, in advance, target line information indicating an arrangement target of an object to be conveyed and related to a target line denoted by at least one of a curve or a polyline. A controller is configured to: calculate, based on the target line information, target information which is at least one of information about a target coordinate of the object and information about a target direction of the object; calculate, based on the at least one of the coordinate of the object and the direction of the object detected by the detector, detection information which is comparable with the target information; calculate a deviation of the detection information from the target information; and cause a display to display a moving direction of the object which allows the deviation to decrease.

Abstract: To allow a worker to visually recognize information for assisting transportation of a transport object and the transport object at the same time. A guidance system includes a guidance device and a controller. The guidance device has a display portion. The controller stores information of a target position of a transport object. The controller calculates a detected position which is a current position of the transport object based on a detection result of a detection portion, and further calculates a position deviation which is a deviation of the detected position from a target position. The display portion displays information of the position deviation.

Abstract: An information exchange system is capable of realizing useful information exchange both for the service provider located along the road and providing services and the vehicular driver, by effectively using limited communication capacity of the road-vehicle radio communication. The information exchange system has a vehicle-mounted unit and a road-side unit providing information to the vehicle-mounted unit using a road-vehicle radio communication. The vehicle-mounted unit includes receiving unit receiving information transmitted from the road-side unit through a radio communication and transferring unit transferring at least a part of a content of the received information to a vehicular occupant. The road-side unit including storage unit storing information to be transmitted to the vehicle-mounted unit and transmitting unit transmitting information to the vehicle-mounted unit through the radio communication.

Abstract: When a vehicle enters a tollhouse and is detected with a vehicle detector, a fixed station transmits a communication link request to a mobile station of the vehicle via an antenna to thereby start transferring toll transfer information between the fixed station and mobile station. During a predetermined release timer time after the communication completion, the communication between the mobile station and fixed station is inhibited, and the mobile station can resume communication upon reception of the communication link request from the fixed station after the lapse of the release timer time. The passing time of the vehicle passing a section between the vehicle detector and another vehicle detector is measured at the fixed station to update the release timer time in accordance with the passing times of vehicles.
