A route setting device, which can provide a route setting device which realize a suitable route setting for each vehicle by using vehicle side data in order to comply with a situation where travel of the vehicle is permitted or prohibited based on the vehicle side data. An ECU sets a destination route by considering the number of passengers as vehicle side data. When the number is only one, that is only driver, the ECU sets the destination route without including carpool lane. On the contrary, when the number is two or more than two, the ECU calculates the destination including the carpool lane. Since many carpool lanes have some advantages compared to the normal roads such that the carpool lane is closer to an exit or the travel distance itself is shorter. Therefore, it can be expected that destination route is set more adequately by including the carpool lane.
