摘　　要：构建上海公交站点的加权网络模型,研究加权网络静态统计性质,包括节点强度分布、加权群聚系数和相关性。研究发现:一个停靠站点上的饱和运输量和该站点的连接密度之间是一种超线性的关系,该发现为分析公交客流量分布提供了重要的借鉴。研究还比较了加权前后集聚系数和节点相关性的变化,发现运输量大的节点之间建立公交线路的可能性也较大,而且这些连接强度较大的节点之间的公交路段交通压力也偏大。文末提出了一些改善这类公交状况的建议。A weighted bus-stop network has been established,based on empirical data,and several static statistical properties have been investigated,including distribution of strength,weighted clustering coefficients,degree-degree correlation,and strength-strength correlation. A super linear relationship between strength and degree has been observed, providing some insights of the understanding of transportation 10ad distribution. The differences between unweighted and weighted clustering coefficient as well as correlation suggest that the possibility of building bus lines among nodes with greater strength is larger ,and the transportation load among them is heavier. Some advices for improving the condition of the public transportation of Shanghai have been addressed in the end.
