Claim 12:
13. A control system for detecting road edges at a predetermined intersection, comprising:
a controller programmed to:
receive aerial imagery data about the predetermined intersection;
receive 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;
detect, using the aerial imagery data and generative adversarial networks (GANs), road edges at the predetermined intersection;
classify, 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;
construct, 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

determine lane edges at the predetermined intersection using a homotopy model.
