経路案内データベースのデータ構造
Document Type and Number:
Japanese Patent JP4994256
Kind Code:
B2
Abstract:
It is an object to realize a route guidance that follows a real passage mode without a feeling of wrongness. In a route guidance device, aside from a two-dimensional road network for a route search, a three-dimensional road network used for the route guidance and guiding line shape data are prepared. The guiding line shape data are three-dimensional guidance display data that guide you to go straight through a crossroads, to turn right, to turn left, etc. in accordance with a passage mode or guide you to change a car lane before you enter a crossroads. A link node of the two-dimensional road network is associated with the guiding line shape data through the three-dimensional road network. The route search is carried out by using the two-dimensional road network. The route guidance is carried out by using the guiding line shape data associated with the link node acquired by the route search. This can realize an instinctively understandable route guidance that follows a passage mode without increasing a load of a route search.
