Abstract
A motor vehicle is provided having a collision warning system that can map an upcoming road section for the motor vehicle. The system can evaluate potential paths for the road section based on vehicle travel history information through it. The system can receive the information from a transmitter proximate the road section, such as a roadside transmitter or one or more nearby vehicles having traversed the road section. The road section can include an intersection and the system can determine a lane configuration for at least a portion of it based on vehicle travel history information. The system can calculate a threat of collision for the motor vehicle with a target vehicle based on map data obtained from estimated paths or lane configurations for the road section. Methods pertaining to mapping a road section and operation of the system are also provided.
