To solve the problems in conventional crossings wherein, when a vehicle arrives at a crossing, an indication object for indicating bearings is absent, and to know the bearing, the driver must carry a device such as a compass, some maps use different languages, or a mechanical navigation consumes much energy, and if broken, the driver loses a means to know the position.

The problems can be solved when an indication for indicating the bearing is present as a road indication. Specifically, a natural rule on the earth is utilized. The indication object is installed utilizing the north. By installing the indication object in the crossing, the bearing in which the driver travels from each direction is generally determined by one indication object only.
