Highlights A hierarchical traffic management scheme for fully connected and automated networks. CAV longitudinal travel speeds are determined by distributed roadside processors. Departure times, travel routes, signal timings are optimized by a central controller. Reduce the time required to finish all CAV trips, and ensure no CAV stops. Two mixed-integer nonlinear programs are proposed for arterials and grid networks.

    Abstract Taking advantages of connected and autonomous vehicle (CAV) technologies, this paper proposes to optimize the departure times, travel routes, and longitudinal trajectories of CAVs, as well as signal timings at intersections to achieve a stable traffic state, where no vehicles need to stop before entering any intersection and no queue spillover occurs at any intersection. The departure times, travel routes and signal timings are optimized in central controller, while the vehicle trajectories can be optimized by distributed roadside processors, which together form a hierarchical traffic management scheme. The conventional NEMA phasing structure is applied for signal control, so that no additional safety issue needs to be considered inside crowded intersections. Two mixed-integer nonlinear programs are proposed for achieving the stable traffic state on arterials and in grid networks. Numerical tests are performed to demonstrate the two programs.
