Vehicle-to-pedestrian (V2P) communication and data association for pedestrian position determination and collision avoidance
Various aspects relate to vehicle-to-pedestrian (V2P) communication and collision avoidance using data association of data from different vehicle-to-everything (V2X) devices. In some aspects, a V2X device (e.g., a vehicle) can determine or estimate the location of a pedestrian by associating data pertaining to the pedestrian from multiple V2X devices and sensors. The association of data can reduce the uncertainties of the V2X device in the determination of the pedestrian's location. A vehicle V2X device can send out a warning indication or alert to the pedestrian or a V2X device of the pedestrian.
