Traffic flow stabilization

Link layer controllers for the automated vehicle/highway system (AVHS) architecture proposed in PATH are derived using vehicle conservation flow models. Control laws are developed for three highway topologies: a single lane highway, a highway with multiple discrete lanes and a highway with an arbitrary 2D flow pattern. The control laws obtained for each of the topologies is distributed and is very suited for implementation at the lower levels of the AVHS control hierarchy. Simulation results are described.
