【摘要】According to the traffic flow at each intersection of the road intersections ,a two-dimensional model of traffic and vector was established in polar coordinates ,and the clustering algorithm was combined with cumulative sum (CUSUM ) segmentation al-gorithm .Through the clustering analysis of vector distance under polar coordinates ,the difference of each flow was identified un-der the condition of similar total flow ,and a new time division point was introduced .107 intersections of Suzhou Industrial Park were investigated in this study ,and the timing and simulation were optimized by using Synchro7 software .The new method was compared with the traditional total flow clustering method .Experimental results showed that the delay and stopping time of inter-section were improved to varying degrees .One type of intersection can reduce the delay time by 27％ on the basis of the original time division .%根据道路交叉口各个流向的分流量,在极坐标下建立流量与向量的二维模型,结合累加和(cumulative sum,CUSUM)时段分割算法进行聚类.通过对极坐标之下向量距离的聚类分析,在总流量相似的情况下,区分各分流量的差异,提出新的时段划分点.实际调查苏州工业园区的107个交叉口,通过Synchro7软件进行分时段优化配
时并仿真,将新方法与传统的总流量聚类方法进行对比.实验证明交叉口的延误和停车时间都有不同程度地改善,其中一类交叉口可以在原有的时间段划分的基础上延误时间减少27％. 【总页数】7页(765-771)
