A geospatial database management system is mounted on a host vehicle and manages geospatial data relating to a travel path for the host vehicle, the travel path having one or more lanes. A geospatial database stores data elements indicative of objects and a location of the objects in three-dimensional space. The objects have a lane-level resolution and the location is accurate to within an order of one decimeter or better. A database manager component is configured to maintain the data elements in the geospatial database and receive database queries from a driver assist subsystem configured to assist a driver of the host vehicle. A query processor is coupled to the database manager component and to the geospatial database and is configured to receive the database query from the database manager component. The query processor queries the geospatial database and returns query results to the database manager component. This can be done in real time.
