To provide a route retrieval device that can retrieve a route having few noise as an optimal route.SOLUTION: A route retrieval device comprises: route retrieval request reception means that receives a route retrieval request from a user; discrimination means that discriminates whether a request for a route having few noise is included in the route retrieval request received by the route retrieval request reception means; noise link cost acquisition means that, when it is determined by the discrimination means that the request for the route having the few noise is included in the route retrieval request received by the route retrieval request reception means, acquires a noise link cost; and route retrieval means that, when it is determined in the determination means that the request for the route having the few noise is included in the route retrieval request received by the route retrieval request reception means, retrieves an optimal route having the few noise, using the noise link cost acquired by the noise link cost acquisition means.SELECTED DRAWING: Figure 2
【課題】騒音の少ない経路を最適経路として探索することができる経路探索装置を提供する。【解決手段】利用者からの経路探索要求を受け付ける経路探索要求受付手段と、経路探索要求受付手段で受け付けた経路探索要求に、騒音の少ない経路の要求が含まれているか否かを判別する判別手段と、判別手段で、経路探索要求受付手段で受け付けた経路探索要求に、騒音の少ない経路の要求が含まれていると判別したときに、騒音リンクコストを取得する騒音リンクコスト取得手段と、判別手段で、経路探索要求受付手段で受け付けた経路探索要求に、騒音の少ない経路の要求が含まれていると判別したときに、騒音リンクコスト取得手段で取得された騒音リンクコストを用いて、騒音の少ない最適経路を探索する経路探索手段とを備える。【選択図】図2
