Abstract
A driving lane planning device, a storage medium, and a driving lane planning method are provided, in which a vehicle selects a lane that is presumed to reflect the driver's intention in a branching terrain. The driving lane planning device includes: a branch determination unit that determines whether there is branching terrain within a predetermined driving range from the vehicle's current position, the branching terrain having a first lane and a second lane adjacent to the first lane, the first lane branching at a branch start position into a third lane and a fourth lane extending in the vehicle's direction of travel; an information acquisition unit that, when there is branching terrain within the driving range and the vehicle is in front of the branch start position, acquires lane movement information that has occurred in the past between the first lane and the second lane; and a driving lane planning unit that, based on the lane movement information, selects one of the third lane and the fourth lane as the lane to travel in at the branch start position, and generates a driving lane plan representing the predetermined driving lane of the vehicle in the driving range.
