| Abstract: | The index system and methods of evaluation of road networks are expounded in detail. With the support of GIS, based on road networks in Gansu province, the evaluation of road networks of each county is made by using ArcView GIS, MapObjects, and visual Basic. The results have shown that the converging centers of road networks do exist in Gansu province, and there is a high value band region in Yumen and also high values of road accessibility in Lanzhou city, in Qincheng district of Tianshui, in Xifeng of Qingyang prefecture, ect. |
