Claims (5)

a position acquisition unit that acquires position data of the mobile object at predetermined time intervals;
an output unit that outputs wrong-way driving notification information indicating wrong-way driving;
A control unit that controls the output unit,
The control unit includes:
The position indicated by the position data acquired by the position acquisition unit changes sequentially, and the target passes through a predetermined detection position set in the passage, and furthermore, the position indicated by the position data acquired by the position acquisition unit changes. An information output device configured to output the wrong-way notification information to the output unit when the detection position is passed . a storage unit that stores the point data indicating the detected position;
a detection unit that detects that the mobile object has passed the detection position based on the position data and the point data;
The information output device according to claim 1, further comprising: a communication unit that acquires the point data indicating another detection position from a server when the detection unit detects passage of the detection position by the moving object. . The other detection positions include a second detection position set at a predetermined interval from the first detection position, and a third detection position set at a predetermined interval from the second detection position. including the location;
The communication department includes:
When the detection unit detects passage of the first detection position by the moving body, the point data indicating the second detection position and the third detection position, respectively, is determined by the point data indicating the point data indicating the second detection position and the third detection position. Acquired as the point data corresponding to the detected position in a valid state in which the detection unit can search, or in an invalid state in which the detection unit cannot search,
The detection unit includes:
The information output device according to claim 2, wherein when passage of the second detection position by the moving object is detected, the point data indicating the third detection position is switched from the invalid state to the valid state. Some of the other detection positions are set as cancellation detection positions for detecting passage of the mobile object that is not traveling in the opposite direction,
The communication department includes:
When the detection unit detects passage of the first detection position by the movable body, the second detection position and the third detection position are set in a second passage branching from the first passage set. Obtaining the point data corresponding to the detected position,
The detection unit includes:
4. The information output device according to claim 3, wherein when detecting passage of the cancellation detection position by the moving body, the point data acquired from the server is deleted from the storage unit. Control processing is performed on a computer that includes a position acquisition unit that acquires position data of a moving object at predetermined time intervals, an output unit that outputs wrong-way notification information indicating that the vehicle is traveling in the wrong direction, and a control unit that controls the output unit. A control program that
The control process includes:
The position indicated by the position data acquired by the position acquisition unit changes sequentially, and the target passes through a predetermined detection position set in the passage, and furthermore, the position indicated by the position data acquired by the position acquisition unit changes. including the step of outputting the wrong-way notification information to the output unit when the vehicle passes the detection position;
control program.
