By using correlation dates of Xueyuan Road and Jingsong Middle Road in Beijing,traffic flows on urban roadways are studied in the paper,the results that based on the analysis of influences to traffic flows on urban roadways which caused by crossroads signal show that the statistical intervals should less than signal cycle of upriver and downriver crossroads.
文中以城市干道交通流为研究对象,应用北京市学院路和劲松中街的相关数据,在分析交叉口信号对城市干道交通流影响的基础上得到:统计间隔的确定应小于上、下游交叉口的信号周期;通过比较以20s、1min、2min、3min、4min和5min为统计间隔而得到的曲线模型,得出以2min、3min、4min和5min为统计间隔较以20s和1min更为合理,且以2min为统计间隔得到的城市干道曲线模型与实际更为相符,建议以2min为统计间隔进行城市干道交通流数据的处理。

Based on the data of Guangfo Expressway, the different average speeds and densities taken separately from different flow sections, choosing 15min, 5min and 1min as statistical intervals, are compared one another and so are the maximum frequency speeds and densities from the same flow sections.
利用广佛高速公路的数据，首先比较了以15min、5min和1min为统计间隔统计的各流率区间内的速度、密度均值，以及最高频率出现的速度、密度值，然后比较了以15min、5min和1min为统计间隔的统计结果标定的Greenshields模型和Underwood模型，认为：标定交通流模型时，可采用的最小统计间隔为5min;当模型精度要求为10％时，最小统计间隔为1min。

采样间隔统计分析法
3) headway calculation
间隔计算
5) time interval meter
时间间隔计
