vertex distance

Each vertex in average distance of each radian located in circumference.

各顶点相互以平均的弧度距离坐落在圆周上.

The edge weight straight-line distance between every two stations will be got by computing the vertex weight. Further we model the BTN to a weighted complex network.

在此基础上，引入了网络点权，即站点的经纬度，进而得到网络的边权，即站点间的直线距离，把公交网络进一步建模成一个加权的复杂网络模型。

Besides, by establishing vertex degree distance matrix, the traditional algorithm for MCI is simplified and the calculating efficiency, veracity, and program attainability for MCi are im-proved.

此外，通过建立点价距离矩阵，简化了传统MCI的计算方法，使MCI的计算具有效率高、不易出错等优点，便于MCI计算程序化。
