Route search device, server device and navigation device
First Claim
1. A route search device, comprising:
- map data of a road map;
a derived route acquisition section that acquires a first derived route for a mobile body from an origin point of the mobile body to a destination of the mobile body;
a route correction region acquisition section that acquires a route correction region corresponding to the first derived route;
a place to be passed through setting section that sets a place to be passed through in the route correction region;
a start point and end point setting section that sets a start point and an end point in the route correction region;
a corrected route acquisition section that acquires a corrected route, not included in the first derived route, from the start point and passing through the place to be passed through to arrive at the end point;
a route correction section that corrects the first derived route to a second derived route from the origin point to the destination, constituted by a route from the origin point to the start point, the corrected route, and a route from the end point to the destination; and
a pass through frequency storage section that stores, included in the map data, pass through frequencies by a plurality of mobile bodies that pass through at least one of a plurality of intersections and a plurality of roads;
wherein the place to be passed through setting section, by referring to the pass through frequency storage section, sets at least one of an intersection and a road whose pass through frequency is high as the place to be passed through.
