Abstract:
We consider optimally coordinated freeway traffic control for networks containing bottlenecks with capacity drop and hysteresis behavior. Due to the multitude of traffic jams, and the spatial and temporal relationships between control actions and traffic behavior, this problem is not as straightforward as for local control. The order in which the measures are applied may be relevant, or it may be possible that not all jams can be resolved. In that case the best possible locations of jams should be determined. We develop an approach that addresses these problems, where we use a generalized representation of flow-limiting control measures and bottlenecks. We determine whether a certain set of control measures is sufficient to improve the network performance. The approach also supplies the necessary sequence of control actions and the necessary relocation of traffic jams to achieve the network state corresponding to the best achievable performance.
