Abstract
Travel guidance devices, methods, and programs acquire map data including a road network, a position of a vehicle, and a planned travel route of the vehicle. Based on the acquired information, the devices, methods, and programs determine whether there is a planned entry branch that the vehicle is projected to enter located ahead of the vehicle. When the planned entry branch is ahead of the vehicle, the devices, methods, and programs determine whether there is a no-lane-change zone between the vehicle and the planned entry branch. When the no-lane-change zone is located between the vehicle and the planned entry branch, the devices, methods, and programs set guidance content related to a lane change of the vehicle based on a position of the no-lane-change zone. The devices, methods, and programs generate guidance using the set guidance content and communicate the generated guidance to a user of the travel guidance device.
