Abstract
Disclosed is a feature for a vehicle that enables taking precautionary actions in response to conditions on the road network around or ahead of the vehicle, in particular, an intersection located at the bottom of a hill. A database that represents the road network is used to determine locations where an intersection of roads is located at the bottom of a hill and then, precautionary action data is added to the database to indicate such locations. A precautionary action system installed in a vehicle uses this database, or a database derived therefrom, in combination with a positioning system to take a precautionary action as the vehicle approaches such a location.
