Abstract: In this paper, a roadway controller is designed, analyzed and simulated for a single automated highway lane that achieves desired traffic densities along the lane. A macroscopic traffic flow model that is modified for AHS (Automated Highway Systems) operation is used for control design and analysis. The authors show that the proposed roadway controller guarantees exponential convergence of the traffic density at each section of the lane to the desired density. Simulation results are used to illustrate the effectiveness of the proposed controller and the significant benefits AHS may bring to traffic flow.
