Roadway controller for automated highway system

In this paper a roadway controller is designed, analyzed and simulated for single automated highway lane which consists of vehicles equipped by cruise controllers keeping the desired safety distance which is made to depend on the following vehicle velocity. Main results of the paper are the following. Macroscopic traffic flow model for mean speed evolution which takes into account command speed generated by roadway controller. Roadway controller which provides the desired traffic density distribution in the presence of stream disturbances such that entrance and egress of vehicles. Results are confirmed by simulation.
