Conflict Analysis for Cooperative Merging Using V2X Communication

In this paper we investigate the problem of a vehicle merging to a main road while another vehicle is approaching on that road. We utilize conflict analysis to help the decision making and control for vehicles of different automation levels. We demonstrate that using vehicle-to-everything (V2X) communication, e.g., basic safety message (BSM), we are able to prevent conflict between the two vehicles. We design a longitudinal controller for the merging vehicle and show that V2X communication is also beneficial in improving the time efficiency of the merge. The results are demonstrated by performing simulations based on real highway data.
