ROUTE SEARCH DEVICE
Document Type and Number:
Japanese Patent JP2017190964
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a route search device capable of searching a route while considering factors in addition to congestion condition (traffic congestion), i.e., considering a case where a route is restricted depending on the size of a moving body and a cargo (traffic is limited by a weight and a vehicle width) to increase the efficiency of transportation.SOLUTION: Disclosed route search device divides a route from plural start points to plural destination points on the basis of node units and identifies a route while considering the cost on each node. In this case, the route search device calculates the cost while considering movement of other moving bodies. That is, the route search device identifies first a route of a moving body having the priority. As for the route, a numerical value which represents the cost in each node is increased, and the route is searched for in a direction to avoid these nodes.SELECTED DRAWING: Figure 1
