TRAFFIC INFORMATION DISTRIBUTION SYSTEM AND TRAFFIC INFORMATION SYSTEM, TRAFFIC INFORMATION DISTRIBUTION PROGRAM, AND TRAFFIC INFORMATION DISTRIBUTION METHOD
First Claim
1. A traffic information distribution system that distributes, to a target vehicle, traffic information including information on a wrong-way vehicle traveling in a wrong-way direction opposite to a designated travel direction of a road, the system comprising:
- a controller that;
distributes the traffic information to the target vehicle;
determines a reporting range of the wrong-way vehicle information based on a wrong-way vehicle position, each section of the road being set between two adjacent branch points on the road, a wrong-way section being the road section in which the wrong-way vehicle is present;
when an end-point distance is equal to or larger than a predetermined reference distance, sets the wrong-way section as the reporting range, the end-point distance being a distance between an end point located on the wrong-way direction side of the wrong-way section and the wrong-way vehicle position;
when the end-point distance is less than the reference distance, sets the wrong-way section and at least one road section which is adjacent to the wrong-way section in the wrong-way direction as the reporting range; and
when the target vehicle is in the reporting range, sends the traffic information including the wrong-way vehicle information to the target vehicle.

Abstract
Systems, methods, and programs distribute traffic information including information on a wrong-way vehicle traveling in a wrong-way direction opposite to a designated travel direction of a road. The systems, methods, and programs distributes the traffic information to the target vehicle, determine a reporting range of the wrong-way vehicle information based on a wrong-way vehicle position. When an end-point distance is equal to or larger than a predetermined reference distance, the systems, methods, and programs set a wrong-way section as the reporting range. When the end-point distance is less than the reference distance, the systems, methods, and programs set the wrong-way section and at least one road section which is adjacent to the wrong-way section as the reporting range. When the target vehicle is in the reporting range, the systems, methods, and programs send the traffic information including the wrong-way vehicle information to the target vehicle.

8. A traffic information distribution method for distributing, to a target vehicle, traffic information including information on a wrong-way vehicle traveling in a wrong-way direction opposite to a designated travel direction of a road, the method comprising:
-
distributing the traffic information to the target vehicle; determining a reporting range of the wrong-way vehicle information based on a wrong-way vehicle position, each section of the road being set between two adjacent branch points on the road, a wrong-way section being the road section in which the wrong-way vehicle is present; when an end-point distance is equal to or larger than a predetermined reference distance, setting the wrong-way section as the reporting range, the end-point distance being a distance between an end point located on the wrong-way direction side of the wrong-way section and the wrong-way vehicle position; when the end-point distance is less than the reference distance, setting the wrong-way section and at least one road section which is adjacent to the wrong-way section in the wrong-way direction as the reporting range; and when the target vehicle is in the reporting range, sending the traffic information including the wrong-way vehicle information to the target vehicle. - View Dependent Claims (9, 10, 11, 12, 13)

14. A computer-readable storage medium storing a computer-executable traffic information distribution program usable to distribute, to a target vehicle, traffic information including information on a wrong-way vehicle traveling in a wrong-way direction opposite to a designated travel direction of a road, the program comprising:
-
instructions for distributing the traffic information to the target vehicle; instructions for determining a reporting range of the wrong-way vehicle information based on a wrong-way vehicle position, each section of the road being set between two adjacent branch points on the road, a wrong-way section being the road section in which the wrong-way vehicle is present; instructions for, when an end-point distance is equal to or larger than a predetermined reference distance, setting the wrong-way section as the reporting range, the end-point distance being a distance between an end point located on the wrong-way direction side of the wrong-way section and the wrong-way vehicle position; instructions for, when the end-point distance is less than the reference distance, setting the wrong-way section and at least one road section which is adjacent to the wrong-way section in the wrong-way direction as the reporting range; and instructions for, when the target vehicle is in the reporting range, sending the traffic information including the wrong-way vehicle information to the target vehicle.
