Abstract
Provided are a method and a system for collision avoidance between vulnerable road users (VRUs) and vehicles, notably for pedestrian-to-vehicle (P2V) collision avoidance, in the field of intelligent transportation technology and data analytics distributed among edge and cloud systems. In one aspect, the method and the system for collision avoidance between VRUs and vehicles is further based on a reflected optical signal, wherein VRUs and vehicles are configured to emit and receive a proximity signal pertaining to road usage safety before accidents happen. The method and the system for pedestrian-to-vehicle (P2V) collision avoidance is further based on a reflected optical signal analysis at the edge. The method and system are useful for providing danger notifications pertaining to the field of road safety, and pertaining to collision avoidance before accidents happen.
