Multi-destination traffic flow control in automated highway systems
Traffic flow control in automated highway systems (AHS) is addressed. A link layer controller for a hierarchical AHS architecture is presented. The controller proposed in this paper stabilizes the vehicular density and flow around predetermined profiles in a stretch of highway using speed and lane changes as control signals. Multiple lane highways in which vehicles have different destinations and types are considered. The control laws are derived from a model based on a principle of vehicle conservation and Lyapunov stability techniques. The implementation requires only local information. Simulation results are presented.
