摘　　要：城市人员出行的规律可以通过道路交通流的特征来反映。研究不同类型时间的交通流变化规律,并引入相似系数和波动系数来研究交通流特征。研究结果表明,不同类型时间的交通流表现出不同的变化规律,同类时间的交通流在时间轴上的变化趋势具有显著的相似性,而交通流参数绝对值则更多地呈现出显著的波动性。The rule of city travel can be reflected by the characteristics of road traffic flow. In this paper, the change rule of traffic flow in the different types of the time is studied and the similarity coefficient and fluctuation coefficient are introduced to study road traffic flow characteristics. The results show that traffic flows in the different types of time show up the different change rules. The change trends of traffic flows at the same time are significantly similar on the time axis, but the absolute value of the traffic flow parameters more shows the significant fluctuation.
