PROBLEM TO BE SOLVED: To perform route search under the consideration of the influence of another vehicle other than a target vehicle.SOLUTION: A route specification part 20 configured as a function achieved by a control part specifies a route to a destination of a target vehicle under the consideration of route information acquired by a vehicle route information acquisition part 201, which indicates a route where another vehicle is scheduled to pass, restriction information acquired by a restriction information acquisition part 202 and traffic information acquired by a traffic information acquisition part 203. Concretely, the route specification part 20 comprises: a route candidate calculation part 204 for calculating a plurality of route candidates to a destination of a target vehicle; a simulation part 205 for applying the route information of the other vehicle, traffic light information (restriction information) and traffic information to the plurality of calculated route candidates, and for simulating a required time to the destination of the target vehicle under the consideration of them; and a route selection part 206 for selecting a route to be guided to a driver of the target vehicle on the basis of the required time as a simulation result by the simulation part 205.SELECTED DRAWING: Figure 5 【課題】対象車両以外の他車両の影響を考慮した経路探索を行う。【解決手段】経路特定部２０は、制御部によって実現される機能であり、他車経路情報取得部２０１により取得された他車両の通行予定の経路情報、制限情報取得部２０２により取得された制限情報、及び交通情報取得部２０３により取得された交通情報を考慮して、対象車両の目的地までの経路を特定する。具体的には、経路特定部２０は、対象車両の目的地までの複数の経路候補を算出する経路候補算出部２０４と、算出された複数の経路候補に対し、他車両の経路情報、信号機情報（制限情報）及び交通情報を適用して、これらを考慮した対象車両の目的地までの所要時間をシミュレートするシミュレート部２０５と、シミュレート部２０５によるシミュレート結果である所要時間に基づいて、対象車両の運転者に対して案内すべき経路を選択する経路選択部２０６とを備えている。【選択図】図５
