Abstract:
1. A method of cooperatively sharing traffic safety sensor data between vehicles for avoidance of a pedestrian-vehicle collision in a crosswalk, comprising: using a detection sensor of a detecting vehicle to detect a pedestrian in or proximate to the crosswalk; determining a relative position of the pedestrian in a coordinate system relative to the detecting vehicle; using GPS equipment of the detecting vehicle to determine at least a GPS location of the detecting vehicle; accessing data stored in memory of the detecting vehicle to determine GPS crosswalk boundary data; using the GPS crosswalk boundary data and the GPS location of the detecting vehicle to determine a global location of the pedestrian; defining a crosswalk path of the pedestrian; using communications equipment of the detecting vehicle, communicating the following data to a receiving vehicle; the GPS location of the detecting vehicle, the GPS crosswalk boundary data, and the global position of the pedestrian; repeating the communicating step for as long as the pedestrian is in the crosswalk path; using communications equipment of the receiving vehicle to receive the data; and using processing equipment of the receiving vehicle to evaluate the relevance of the data to collision avoidance between the receiving vehicle and the pedestrian.
