The rapid development of connected and automated vehicle (CAV) technologies will undoubtedly revolutionize the traffic control system. Although the duration of the transitional process from the state-of-the-practice to the future “signal-free” system is uncertain, it is important for both traffic management agencies and traffic control industry to understand what might be happening during the transition process and how we can better prepare and facilitate the transition. In the following, it presents our road-map to the next generation traffic control system.
