Digital Twin, as an emerging technology related to Cyber-Physical Systems (CPS) and Internet of Things (IoT), has attracted increasing attentions during the past decade. Conceptually, a Digital Twin is a digital replica of a physical entity in the real world, and this technology is leveraged in this study to design a cooperative driving system at non-signalized intersections, allowing connected vehicles to cooperate with each other to cross intersections without any full stops. Within the…

A consensus-based distributed trajectory control in a signal-free intersection
TLDR
The results show that the proposed distributed coordinated framework converges to near-optimal CAV trajectories with no conflicts in the intersection neighborhood, while eliminating all near-crash conditions.
Cooperative Intersection Control Based on Virtual Platooning
TLDR
Both safe passage of the vehicles through the intersection and a high intersection throughput (due to close “virtual” vehicle following) can be achieved.

Bringing simulation to life: A mixed reality autonomous intersection
TLDR
Several techniques to improve efficiency are presented and it is shown that the AIM protocol can still outperform traffic signals and stop signs even if the cars are not as precisely controllable as has been assumed in previous studies.
Cooperative Adaptive Cruise Control in Real Traffic Situations
TLDR
The design, development, implementation, and testing of a CACC system, which consists of two controllers, one to manage the approaching maneuver to the leading vehicle and the other to regulate car-following once the vehicle joins the platoon, is presented.
Decentralized traffic management: A synchronization-based intersection control
TLDR
This paper proposes a synchronization-based intersection control mechanism to allow the autonomous vehicle-agents to cross without stopping, i.e., in order to avoid congestions and energy loss, and presents experimental results in simulation.
