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. User reports of hazardous conditions along roads are obtained and analyzed to identify reports that pertain to the same general location along a road network. A database that represents the road network is used to confirm the user reports, identify the hazardous condition, and determine locations where precautionary action may be taken. Then, precautionary action data is added to the database to indicate a location at which a precautionary action is to be taken about the user-reported hazardous condition located along the section of road. 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 a user-reported hazardous condition.
