| 摘 要： | 该文研究了路段流量序列间互相关系数与其空间距离的关系.通过对城市路网各路段交通流量序列进行互相关分析,研究了网络交通负荷、交通流日变化趋势及流量采样周期对该关系的影响.结果表明:间距相同的若干路段对的互相关系数各不相同;在统计意义下,路段间平均互相关系数随路段空间距离增大而减小;随着交通网络负荷的增加网络交通流渐趋拥堵...

| Abstract: | This work investigates the relationship between the traffic flow series' cross correlation coefficient(CCC) and the spatial distance of the road network sections.A cross correlation analysis(CCA) is used to analyze the traffic flow time series in each section within the traffic network to study the influences of traffic load,daily flow trends and sampling period on the CCA of the traffic flow series.These studies show that the CCC of section pairs with the same distance differ from each other.However,the me... |
