  • Publication number: 20230339470
    Abstract: A first closed lane segment file including a first lane change histogram and a lane closure start point associated with a closed lane segment of a first lane of a road is received from a lane change data aggregation system at a lane change management system. The first lane change histogram includes a distribution of a plurality of lane change points received from vehicles that previously engaged in a lane change from the first lane to a second lane of the road in response to the closed lane segment. A lane change control point is determined based on the first lane change histogram at the lane change management system. A command is issued from the lane change management system to an ADS of the autonomous vehicle to initiate a lane change from the first lane to the second lane at the lane change control point.
