摘要

To make buses more attractive to users, transportation services aim to assure their efficiency and reliability, but these are subjected to traffic conditions. To do that, it is possible to grant them priority at traffic lights, but this solution is not efficient. In a dense traffic context, priority is not enough since it may lead buses to congestion. The spread of communication technologies in vehicles and personal devices enables new solutions. Regulation mechanisms based on real-time information are possible and allow intersections to apply a fine regulation policy with no traffic lights needed. We develop a distributed coordination-based mechanism using a constraint-based model allowing buses to reserve the right-of-way on their trajectory. With this mechanism, each intersection on this trajectory adapts its regulation policy in order to provide a clear path for the bus, allowing it to reach the bus stops in time. The policy of an intersection is based on a bi-level coordination model with the vehicles.
