A coordination algorithm for road traffic control measures

This paper proposes a coordination algorithm for road traffic control measures, which would greatly extend the set of possible control measures that can be applied simultaneously. It is based on experiences with motorway traffic management in the Netherlands. It is also a case study in combining hierarchical control with coordination and cooperation mechanisms. The algorithm deals only with soundness of sets of simultaneously applied control measures, which is a necessary condition for the synergy of the applied measures. The essence of the algorithm is a translation of traffic control measures into so-called atomic effects on lane segments. The paper also describes the implementation strategy for the algorithm.
