Abstract
The problem of vehicle traffic flow control in automated highway systems is analyzed. Given desired vehicular density and velocity profiles along a highway, stabilizing velocity controllers are designed so that the real vehicle traffic flow converges to the desired profiles. The controllers are derived using vehicle conservation flow models and Lyapunov stability techniques. A highway topology with a discrete number of lanes is considered. Vehicles can have different destinations and perform diverse maneuvers. The control law obtained is distributed and therefore is suited for implementation on AHS hierarchical multilayer architectures. Simulation results are presented.
