本文对由地铁和铁路线组成的首尔公共交通系统进行了分形研究。整个网络的分形维数是几年来确定的，表明线的实际分形维数D从1.15-1.35增加。我们还确定了观测站整体的实际尺寸（1.50）。我们讨论了站点的分形维数大于线路的分形维数的意义，并得出结论，它可以作为系统质量的一个度量。我们的结果与巴黎的结果进行了比较，也确定了巴黎的两个分形维数。(C) 2002年Elsevier Science Ltd.出版
We present a fractal study of the public transportation system of Seoul, composed of subway and railway lines. The fractal dimension of the whole network is determined for several years, indicating an increase of D, which is the actual fractal dimension of the lines, from 1.15-1.35. We also determined the actual dimension of the ensemble of the stations (1.50). We discuss the significance of the fact that the fractal dimension of the stations is larger than that of the lines and conclude that it could be a measure of the quality of the system. Our results are compared with those concerning Paris, for which the two fractal dimensions have also been determined. (C) 2002 Published by Elsevier Science Ltd.
