Claim 0:
1. A method for detecting road edges at a predetermined intersection, comprising:
receiving, by a controller, aerial imagery data about the predetermined intersection;
receiving, by the controller, vehicle telemetry data gathered within a predetermined radius around the predetermined intersection from a plurality of vehicles passing through the predetermined intersection, wherein the vehicle telemetry data includes a plurality of telemetry data points;
detecting, using the aerial imagery data and generative adversarial networks (GANs) executed on the controller, road edges at the predetermined intersection;
classifying, using a random forest classifier (RFC), the predetermined intersection with each telemetry data point labeled with a corresponding unique maneuver to create a maneuver-labeled telemetry data points at the predetermined intersection;
constructing, using the maneuver-labeled telemetry data points determined by the RFC and the road edges, a probabilistic finite state automata (PFSA) to pair inbound lanes with outbound lanes at the predetermined intersection; and
determining lane edges at the predetermined intersection using a homotopy model.
