基于GIS的安徽省交通网络可达性分析

Analysis of Accessibility of Transportation Network in Anhui Province Based on GIS

摘要: 自21世纪初以来，随着经济的稳定和快速增长，城市化和产业化的进程急剧加快，对城市交通的需求呈指数增长，道路问题一直是城市发展的主要关注之一。运输问题是一个涉及政治、经济学和其他许多方面的大而复杂的问题，建立可持续、高效的运输系统是政府的重要问题。本文分析了安徽省城市可达性差异的空间规律，并在本地可达性分析中使用标准差分析了城市位置因素在区域可达性中的作用。最后，针对路网布局的一些弊端提出了相应的建议。

Abstract: Since entering the 21st century, with the sustained and rapid economic growth, the process of ur-banization and industrialization has increased and the traffic demand of cities has also increased sharply. The traffic problem has become one of the important problems that perplex the urban de-velopment. Traffic problem is a huge and complex problem, which is related to political, economic and other factors. Therefore, it has become an important task for the government to build a smooth and efficient urban transportation system. This paper analyzes the spatial differentiation of Urban Accessibility in Anhui Province, and analyzes the role of urban location factors in regional accessi-bility by using standard deviation in the analysis of global and local time accessibility. Finally, the paper puts forward some suggestions for the disadvantages of road network layout.
