1. A vehicle system comprising:
- a database that contains data representing a geographic region in which a vehicle is being operated, wherein the data includes data that represents a road network located in the geographic region and precautionary action data that indicates precautionary action locations associated with locations where a combination of conditions exist, wherein the combination of conditions comprises an intersection of roads located at a bottom of a hill;
a positioning system that determines a current location of the vehicle relative to the data representing a geographic region; and
a precautionary action application responsive to the positioning system and the database that provides a precautionary action when the positioning system determines that the vehicle is approaching a location associated with precautionary action data.

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.
