Self-driving vehicle technologies are expected to play a significant role in the future of transportation. One of the main challenges on public roads is the safe cooperation and collaboration among multiple vehicles using inter-vehicle communications. In particular, road intersections are serious bottlenecks of urban transportation, as more than 44% of all reported crashes for human-driven vehicles occur within intersection areas. At merge point, which corresponds to an intersection type, serious traffic accidents often occur, and collaboration and cooperation is critical in the area. In this work, we present a safe traffic protocol for use at merge points, where vehicles arriving from two lanes with different priorities must interleave to form a single lane of traffic. Simulation results show that our cooperative protocol has higher traffic throughput, compared to simple traffic protocols, while ensuring safety.
