摘要
研究了中国3个不同城市的公共汽车运输网的结构性质。这些网络由一系列的公交车路线和车站组成。分别在L空间和P空间对这些网络的度分布,簇团系数和最短路径进行了研究。研究表明:在L空间中,度服从幂律分布,而在P空间服从指数分布;P空间中大的簇团系数和小的平均最短路径表明小世界效应在P空间中更加显著。
The structural properties of 3 bus-transport networks (BTN) are studied in three different cities of China. These networks are composed of a set of bus lines and stations. Network properties including the degree distribution,clustering and average path length are investigated in the space L and P respectively. It is demonstrated that the degree in the space L obeys a power-law distribution while that in the space P follows an exponential distribution. The large average clustering coefficient and small average path length in the space P indicates that the small-world property is more visible in the space P.
