New Dimensions of Intersection Control with Connected and Automated Vehicles

Connected and automated vehicle (CAV) technologies are believed to offer tremendous benefits to the urban transportation system. Intersection control will also experience a transition process from the state-of-the-practice paradigm to a fully CAV deployed environment, and new dimensions will be added to the control framework. In this paper, we envision that the transition process mainly contains three major stages, namely, the detector-free signal operation, the generalized spatiotemporal intersection control, and the infrastructure adaptation. Several key challenges are discussed.
