1. A driving assistance device comprising:
planned travel route obtaining means for obtaining a planned travel route on which a vehicle travels;
traffic congestion conditions obtaining means for obtaining, from an external source, traffic congestion conditions for each lane on the planned travel route;
travel path generating means for generating a travel path, targeting a section from a current location of a vehicle to a location a predetermined distance ahead of the vehicle and using map information including at least information about markings and the traffic congestion conditions for each lane, the travel path identifying a lane change location at which a lane change is made to a recommended lane, and the recommended lane being recommended for the vehicle to travel in on a road included in the planned travel route;
a camera or sensor mounted on the vehicle to obtain road conditions in a predetermined direction range around the vehicle, wherein
the travel path generating means
generates a static travel path, targeting a section from a current location of the vehicle to a location a predetermined distance ahead of the vehicle, the static travel path being the travel path and the section including an area outside the detection range, and
generates a dynamic travel path separately from the static travel path, targeting only an area within the predetermined detection range and using the map information, the traffic congestion conditions for each lane, and road conditions around the vehicle obtained by a vehicle, the dynamic travel path being a travel path recommended for the vehicle to travel along on a road included in the planned travel route; and
autonomous driving assistance means for providing driving assistance travel control for a vehicle, based on at least one of the static travel path and the dynamic travel path.
