• Abstract:
  Vehicle traffic on highway systems are typically not uniformly distributed. In our work, we introduce a protocol that exploits this phenomenon by considering the formations of shock waves and opportunities in adjacent lanes. The objective of this protocol is to reduce the impact of a shock wave by using event-driven messages between vehicles that provide drivers with velocity or lane switching recommendations. We show how our protocol uniformly distributes vehicle densities across multiple lanes while maintaining lane fairness, and reduces the number of vehicles entering a shock wave point. Simulation results show we are able to further reduce the overall travel times and increase the average velocity.
