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. Then, precautionary action data is added to the database to indicate a location at which a precautionary action is to be taken about the intersection of roads located at the bottom of a hill. A precautionary action system installed in a vehicle uses this database, or a database derived therefrom, in combination with a positioning system to determine when the vehicle is at a location that corresponds to the location of a precautionary action. When the vehicle is at such a location, a precautionary action is taken by a vehicle system as the vehicle is approaching an intersection located at the bottom of a hill.
