摘　　要：根据交通量历史统计数据,考虑交通流向的差异性,在平均小时交通量处理的基础上,通过计算信号交叉口的周期时长,设定管控时段划分的判别阈值,对无锡市梁清路-蠡溪路全天24h进行管控时段的划分,为建立全天多时段配时方案提供科学的依据。结果表明:与传统基于交通量统计数据划分方法相比,该方法的时段划分结果更符合实际交通流的变化趋势。According to historical statistics of the traffic volume, considering the differences of traffic flow directions, an intersection traffic control period division method is proposed based on the processing of average hourly traffic volume. In this control method, by calculation of the cycle length of traffic signal at intersection, a control period threshold value is set. Using this method the 24 h of a day is divided into several traffic control periods at the intersection of Liangqing road and Lixi road, Wuxi City. This provides a scientific basis for the establishmen： of signal timing programs with multiple periods a day. Compared with traditional period division method, the calculation results by the proposed method are in good agreement with the actual traffic flow.
