Vehicle to pedestrian communications
Participants : Pierre Merdrignac, Oyunchimeg Shagdar, Evangeline Pollard, Fawzi Nashashibi.
Vehicle and pedestrian collisions often result in fatality and serious injury to the vulnerable road users. While vehicle to vehicle (V2V) communications have taken much attention in the academic and industrial sectors, very limited effort has been made for vehicle to pedestrian communications. Unlike the V2V cases, where antennas are often installed on the vehicle rooftop, pedestrian’s handheld device can be carried in such a way e.g, in a bag or in a pocket, which results in poor and unpredictable communications quality. In this work, we seek to an answer to the question whether the Wi-Fi-based V2P communications meet the requirements of the pedestrian safety. This year, we studied the performances of the V2P communications especially for the receive signal strength, packet inter-arrival time, and message delivery ratio. Moreover, in order to demonstrate the feasibility of pedestrian safety supported by the V2P communications, we developed a software tool, V2ProVu, which has the functionalities of Wi-Fi based V2P communications, collision risk calculations, and hazard alarming.
