Abstract:
Provided is lane guidance system for decreasing the possibility that a user is misled including: a proposed travel route acquisition unit that acquires a proposed travel route of a vehicle; a successive intersection determination unit that determines whether a distance between a first intersection that is a guidance intersection on the proposed travel route and a second intersection that follows the first intersection is within a prescribed distance. Based on the proposed travel route, a travelable lane acquisition unit acquires a travelable lane that the vehicle needs to travel along when entering the first intersection to exit in a specific exiting direction of the first intersection, when the vehicle needs to exit from the first intersection in the exiting direction to travel along the proposed travel route. Before arriving at the first intersection, the lane guidance unit selects and proposes, as a recommended lane from the travelable lane, a lane that the vehicle needs to travel along when entering the first intersection after exiting from the first intersection, a lane that the vehicle needs to travel along when entering the second intersection to exit in a specific exiting direction of the second intersection, when the vehicle needs to exit from the second intersection in the exiting direction to travel along the proposed travel route when the a distance between the first intersection and the second intersection is within a prescribed distance.
