Abstract
A self-driving road vehicle stores an active driving map that includes a data store of route feature data together with a software or control system that periodically selects from the data store and provides to systems on the vehicle the route feature data that are relevant to the vehicle location and the route that the vehicle is following. The route feature data may include a sequential series of road cross-section data objects that represent a real-world roadway being traversed by the vehicle. Methods for operating the self-driving road vehicle include providing route feature data from an active driving map, which may include the sequential series of road cross-section data objects that represent the real-world roadway being traversed.
