Abstract
In one embodiment, a method includes determining a connectivity model associated with a region of a road network, wherein the connectivity model was trained using vehicle traffic-pattern data comprising a first lane identifier and a second lane identifier indicating one or more lanes associated with a vehicle trajectory through the region and a traffic-light state corresponding to signal information of traffic lights in the region when a vehicle moved through the region, determining for at least one egress lane in the region based on the connectivity model a lane relationship indicating one or more ingress lanes in the region onto which a vehicle in the egress lane can move and one or more governing traffic lights selected from the traffic lights in the region that govern the egress lane, and encoding the lane relationship and the one or more governing traffic lights into a map of the region.
