Abstract
A system generates a high definition map for an autonomous vehicle to travel from a source location to a destination location. The system determines a low resolution route and receives high definition map data for a set of geographical regions overlaying the low resolution route. The system uses lane elements within the geographical regions to form a set of potential partial routes. The system calculates the error between the potential partial route and the low resolution route and removes potential partial routes with errors above the threshold. Once completed, the system selects a final route and sends signals to the controls of the autonomous vehicle to follow the final route. The system determines whether surface areas adjacent to a lane that are not part of the road are safe for the vehicle to drive in case of emergency. The system stores information describing navigable surface areas with representations of lanes.
