PURPOSE:To easily select a path by a user by calculating a travel distance, a travel time, and travel expense, etc., between a start point and an end point by using the attribute information of a storage means, performing weighted addition on those calculated values, and displaying the path in which the min. addition value can be obtained. CONSTITUTION:In the storage means 3, the map data of a road is divided at every branch point, and the attribute data of the travel distance, the travel time, and the travel expense are attached on every division. And when plural paths are prepared between the start point and the end point designated by setting input 1, respective sum value of the travel distance, a time required for the travel, and the expense required for the travel at every travel path are calculated. Afterwards, the weighted addition of those calculated values is performed by a weight coefficient from a weight setting means 6, and the travel path in which the min. addition value can be obtained is displayed on a display device 5. |
