本文从核密度估算和通达性计算两方面出发,在公路网络拓扑结构的基础上对重庆市2015年道路交通网络进行定量分析,从而对重庆市公路交通网络结构现状进行科学的评价,得出以下结论:1重庆市道路网络总体呈以主城区为中心向四周辐射发散的单极网络格局;2重庆市道路发展水平整体较低;3高级公路分布极不均匀,偏远地区较低的高级公路分布率制约着地区经济的发展。
Based on the topological structure of highway network, this paper makes a quantitative analysis of the road network in Chongqing in 2015 from the aspects of nuclear density estimation and accessibility calculation, and then makes a scientific evaluation of the present status of the highway traffic network structure in Chongqing. Conclusions: 1 The road network in Chongqing shows a unipolar network with radiating radiation around the main urban area as a center; 2 the overall level of road development in Chongqing is low; 3 the distribution of highways in the highways is extremely uneven; the distribution of the highways in the remote areas is rather low Rate restricts the development of regional economy.
