摘　　要：提出了诱导子区的概念,对诱导子区内诱导单元协调的重要性进行了研究.提出了相同路口诱导单元的协调策略,对同级诱导单元诱导信息的相互影响进行了探讨,在此基础上将协调区域扩大到上游诱导单元,对诱导子区内诱导单元协调策略进行了研究.作者进行了多次仿真试验并对有代表性的仿真结果进行了分析,从诱导状态估计的准确程度和诱导均衡度2个方面说明了诱导子区协调方法的有效性.Coordination of guidance information in guidance sub-area is one of the key aspects of intelligent Dynamic Route Guidance System（DRGS） to enhance guidance effect and expand the guidance region.The concept of guidance sub-area is proposed,and the importance of coordination in guidance sub-area is studied.A coordination mehtod of guidance unit in the same cross is presented to discuss the effect of guidance unit on the same level.Based on the coordination of the same cross,the idea of expanding the guidance coordination area to the upper guidance units,a coordination strategy of guidance units in the whole sub-area is proposed.Simulation experiments and the analysis of the simulations are presented.The effectiveness of the guidance coordination strategy is verified with the veracity of guidance unit state estimated and the equilibrium of guidance object area.
