ABSTRACT:
Methods and systems for generating, deriving, and enhancing drivable road databases are provided. A baseline road in a road network is defined and position and/or trajectory data collected by vehicles traveling the baseline road are compiled and compared to a representation of the baseline road in an existing database. Identity and/or other property information about the road are assigned form the existing database to the new database.
