Pedestrian to Vehicle Communication: A Safe and Private Solution Proposal

Sammanfattning: Vehicle-to-vehicle communication (V2V) has become one of the most risingtechnologies in recent years, and due to the implementation of 5G different solutionshave begun to be designed that allow communication between vehiclesand pedestrians (V2P). V2P communication is a challenge for two reasons:the incompatibility of technologies, as well as the need to have a real-timecommunication (crucial when sending and receiving road hazard messages).This document presents a solution for pedestrian-to-vehicle communication,detecting pedestrian risk situations using the mobile phone sensors and messagesby the vehicles. An architecture and communication protocol is presented,to send warning messages with low delay in a secure and private waywithout harming efficiency. Two algorithms are used, one implemented in anAndroid application and another one in a server, with the purpose of detectingpedestrian misbehavior in the road and reducing the amount of direct messagesbetween the nodes of the system.
