Cooperative intersection collision avoidance in a constrained communication environment

Paper in proceeding, 2015

Intersections remain among the most accidentprone subsystems in modern traffic. With the introduction of vehicle-to-infrastructure communication, it is possible for the intersection to become aware of the incoming stream of vehicles and issue warnings when needed. We consider an approach where vehicles can act automatically on those warnings, leaving drivers maximal freedom of manoeuvre while guaranteeing safety with minimal intervention. We also quantify the impact of imperfect communication in the uplink (from vehicle to infrastructure) and the downlink (from infrastructure to vehicle).
