%X From the point of view of control theory,the urban intersection signal optimization involving stochastic breakdown is dealt with.Based on the nature of urban intersection and borrowing the idea of optimal production control,a new vehicle flow cost model of road is initiated,with the consideration of the stochastic breakdown at the intersection.Since the system is characterized by multi_horizon and unreliability,which makes it a hierarchical framework,a hierarchical control policy is constructed based on the horizon.Consequently,the optimal control policy of urban intersection signal is gotten.The simulation shows that the model is practical,powerful and promising.
