Abstract
Vehicle driver assistance and warning systems that alert a driver of a vehicle to wrong-way driving and/or imminent traffic control measures (TCMs) are disclosed. The system will identify a region of interest around the vehicle, access a vector map that includes the region of interest, and extract lane segment data associated with lane segments that are within the region of interest. The system will analyze the lane segment data and the vehicle's direction of travel to determine whether motion of the vehicle indicates that either: (a) the vehicle is traveling in a wrong-way direction for its lane; or (b) the vehicle is within a minimum stopping distance to an imminent TCM in its lane. When the system detects either condition, it will cause a driver warning system of the vehicle to output a driver alert.
