Abstract
Provided are a device for automatically generating route restriction information of intersections between main roads and narrow streets, and a method therefor. With respect to a specific intersection which is an intersection between a main road and a narrow street, firstly, it is determined to prohibit a right turn and passing through the intersection. Under these conditions, when it is sufficiently confirmed, by using external information, that the right turn and passing through the intersection can be allowed at the specific intersection, the route restriction regarding the direction is released. Probe information and traffic restriction data are used for the external information.
