低等级公路网布局规划的方法研究

伴随国民经济的不断快速发展,国内公路网的覆盖率快速提升,从主要省市的主干道快速向周边县域延伸,因此低等级公路网的发展得到稳步推进。在低等级公路网的建设中,应用科学有效的方法,并针对庞大且精细的数据量,应用了地理信息系统(GIS)相关技术,实现数据的分析处理,进行路网的科学合理规划。

With the rapid development of the national economy, the coverage rate of the domestic highway network is increasingrapidly, from the main roads of the major provinces and cities to the surrounding counties, so the development of the low-gradehighway network has been steadily promoted. In the construction of low-grade highway network, the scientific and effective method isapplied, and in view of the huge and fine data volume, the GIS （Geographic Information system） technology is applied to realize theanalysis and processing of the data and the scientific and reasonable planning of the road network.
