摘要： A traveling route changing apparatus included in a vehicle determines whether an emergency vehicle is present among nearby vehicles located around the vehicle, tracks a movement of the emergency vehicle, determines whether to change a traveling route of the vehicle such that the emergency vehicle travels without being obstructed by the vehicle, generates candidate routes to change the traveling route of the vehicle, evaluate a risk involved with each of the candidate routes, and control the vehicle based on a candidate route having a lowest risk. Thus, the vehicle may travel along a selected candidate route, and the emergency vehicle may travel without being obstructed by the vehicle.

摘要： A processor-implemented method with lane line determination includes: determining, from an input image, road feature information comprising a surrounding object and a road surface marking comprising a lane line; matching the road feature information to lane lines of a driving road on which a vehicle is driving; detecting whether there is a change in a road structure based on a result of the matching, wherein the change in the road structure comprises any one or any combination of any two or more of a change of the lane line, a loss of the lane line, and a change of a road sign; and based on whether the change in the road structure is detected, determining lane line information of the driving road by using information on the surrounding object.
