Vehicular Cooperative Maneuvers -- Quo Vaditis?

Vehicles will not only get more and more automated, but they will also cooperate in new ways. Currently, human-driven vehicles begin to communicate with each other using vehicle-to-everything technology. Future vehicles will use communication to share sensor data and even negotiate cooperative maneuvers. This lets them learn more about the environment and improves traffic flow and passenger comfort as more predictable maneuvers are likely to lead to a smoother ride. This paper introduces the most important concepts around cooperative vehicular maneuvers. We also summarize currently open challenges and questions to answer before a deployment can begin. Afterward, we give some perspectives on the further evolution of cooperative maneuvers and beyond.
