摘要：

针对目前交叉口的交通状态不能完全反映信号控制情况的问题,提出采用可控性的概念对交叉口的控制状态进行判定.通过定义通过率和阻塞率的综合作用结果,能够利用排队长度界定交叉口是否可控,采用交通波理论对剩余排队进行分析量化可控状态,以可控状态为判断条件建立交叉口信号切换控制模型.在“可控状态”下利用清空策略对交叉口进行控制,在“不可控状态”下将交叉口总排队最小设为目标函数,采用遗传算法求解策略对交叉口进行控制,给出不同控制状态下的控制策略.对实际路口进行仿真验证.结果显示,利用所提方法可以快速对交叉口交通状态进行判定,针对各种状态选择适合的控制策略,保证了交叉口的控制效果,证明了该方法的可行性和有效性.
Abstract:

Judging the traffic condition of intersection using the concept of “controllability” was proposed aiming at the problem of existing methods that judge traffic states can't fully reflect the traffic condition of the intersection. The length of the queue can be utilized by blocking rate defined by the rate and the result of the combined effect in order to define if intersection can be controlled. The traffic wave theory analysis was conducted to quantify the remaining queue for controllable state.  The switching control model of intersection was established by using the controllable state as the judgment condition. In the “controllable state”, the policy was used to take advantage of empty intersection control. In the “uncontrollable state”, the intersection minimum objective function was set by using genetic algorithm strategy intersection control. Control strategy under different control state was given. A real network was selected to conduct a simulation. Results show that using the proposed method of intersection traffic state can quickly be determined. The appropriate control strategy was selected for a variety of state. Then the control effect of the intersection was ensured. The feasibility and effectiveness of the proposed method were proved．
