Abstract
A method and system for representing traffic control signals in a road network database is provided. The database may include lane-level modeling, intersection modeling, and traffic signal modeling of a road network. An individual traffic signal is represented in the database with data indicating the traffic signal's geographic location and other attributes of the traffic signal such as an arrangement of lenses in the signal, an indication as to whether the signal is vertically or horizontally oriented, a height of the traffic signal over the roadway, and others. The database can be used by a system in a vehicle that provides convenience features to the vehicle's driver. The system may attempt to warn or control a vehicle that is determined to be at imminent risk of violating a traffic signal.
