本文建立了公交线网覆盖形态分形评价模型。针对传统网格法手工计算分维数的不足之处,引入了GIS技术,详细介绍了GIS在网格分维计算中的具体应用方法。该模型的实际应用,能大大提高公交线网覆盖度评价的准确性和工作效率。
This paper established a public transport network coverage form fractal evaluation model. Aiming at the shortcomings of traditional grid method for calculating fractal dimension manually, the GIS technology is introduced and the application of GIS in fractal dimension calculation of grid is introduced in detail. The practical application of this model can greatly improve the accuracy and efficiency of the evaluation of the coverage of the public transportation network.
