针对信号交叉口延误—配时之间的复杂联系,通过对目前延误参数的获取情况进行分析,使用实时提取的周期延误值,借助K近邻预测算法,结合交叉口的流量对下个周期的延误进行预测,并使用预测的延误参数对下个周期的控制方案优化方法进行了研究。借助VISSIM仿真平台对提出的方法进行了分析,结果表明使用该方法对配时方案优化后的交叉口车辆延误可以降低13.52%,表明该方法在信号配时优化中有一定的应用前景。

s:There is a complex relation between delay and timing control design at signalized inter-section. The present delay acquisition methods were analyzed. Using the measured real-time cycle delay and considering the traffic flow, the K-nearest neighbor algorithm was used to obtain the next cycle delay, and the forecasted delay was employed to study, the timing optimization of the next cy-cle. Based on an example in VISSIM simulation platform, it is proved that the optimization method described in the paper can decrease the intersection delay by 13. 52%. Therefore, this method has potential applicability to signalized intersection control optimization in the future.
