Abstract

A vehicle-to-pedestrian (V2P) communication system and method of operating same including acquiring V2P parameters from at least one of a first V2P device associated with a user or a second V2P device integrated with a vehicle associated with the user. Detecting a pedestrian state transition of the user based on the V2P parameters. The pedestrian state transition indicates at least one of a change in a classification of the user from a pedestrian state to a driver state or a change in the classification of the user from a driver state to a pedestrian state. Further, the method includes warning to at least one of the user or one or more entities in proximity to the user using the V2P parameters, the pedestrian state transition, and the vehicle parameters.
