A system for generating a path allows a vehicle to traverse a predetermined route. The system stores route data for the predetermined route. The route data identifies a series of contiguous path segments that form the predetermined route. The route data also identifies a series of nodes located at the beginning and the end of the predetermined route and between adjacent path segments. Each path segment represents a series of postures along the predetermined route. Each posture identifies a position, a heading, and a curvature for the vehicle at a particular point along the predetermined route. The system stores the path segments and nodes as compressed path data. In one embodiment, the compressed path data is a function that is continuous in posture, i.e., continuous in position, heading and curvature. The system retrieves the compressed path data and generates a series of postures from the retrieved compressed path data to allow the vehicle to traverse the predetermined route.
