A method and computer are provided on a vehicle 110 that receive information from each of a plurality 120 of vehicles information about the vehicles geolocations and distances from a lane border, define clusters L1, L2, L3 of vehicles 120 based on the data and identify lane boundaries from the clusters to generate a lane map. The system may determine lane curvature and may fit a curve to travelled locations of vehicles 120. The system may involve inter-vehicle communication and may take into account traffic data and road construction data as well as the yaw angle of vehicle 110. The updated map may be broadcast to a server.
