Abstract: Traditionally traffic signal systems are designed in such a way that different time slots are allocated to conflicting traffic streams in order to ensure vehicle safety. In the future, such design constraints may be relaxed with connected and automated vehicle (CAV) streams because crash avoidance can be achieved through distributed control of vehicle trajectories, therefore traditional traffic signals may no longer be needed.
In this talk, we will discuss the opportunities and challenges for traffic control systems with varying percentages of connected and automated vehicles. In particular, we will present our findings using the massive data set collected from the Safety Pilot Model Deployment project and Ann Arbor Connected Vehicle Test Environment, both supported by USDOT.
