Abstract: In one embodiment, perception data is received from a number of autonomous driving vehicles (ADVs) over a network. The perception data includes information describing a set of trajectories that a number of vehicles having driven through a road segment of a road and perceived by one or more ADVs using their respective sensors driving on the same road segment. In response to the perception data, an analysis is performed on the perception data, i.e., the trajectories, to determine one or more lanes within the road segment. For each of the lanes, a lane reference line associated with the lane is calculated based on the trajectories within the corresponding lane. The lane metadata describing the lane reference lines for the one or more lanes are stored in a lane configuration data structure such as a database. The lane configuration database can then be utilized for autonomous driving at real-time subsequently without having to use a high definition map.
