地理信息系统(GIS)在公路客运换乘站选址布局中的应用

Application of GIS in site selection for the exchange station for highway passenger transportation

随着我国城市化进程速度的不断加快,许多城市都面临着现有交通基础设施无法满足交通需求的矛盾,产生了诸如交通堵塞、停车困难、换乘不便、环境恶化等一系列交通问题。如何在现有的交通供给水平下,实现各种交通方式的有效衔接,建立高效、安全、便捷的综合交通运输体系,关键是解决城市综合运输枢纽中客运换乘站选址布局问题。由于公路客运场换乘站可将城市内部交通和对外交通有机地联系起来,其选址布局相对比较灵活,所形成的不同布局方案对城市综合运输枢纽的运输能力、整体运营成本和效益有着很大影响,因此本文在对公路客运换乘站布局影响因素分析的基础上,运用地理信息系统(GIS)工具对公路客运场换乘站选址布局进行分析研究,使得选址布局更具合理性,促进交通一体化更好的发展。

With the acceleration of Chinas’urbanization process, many cities have the contradiction that the existing traffic infrastructure can’t meet the traffic demand and such problems as traffic jams,difficulty in parking,inconvenience in exchange and environment deterioration.The site selection for the exchange station for highway passenger transportation is the key to realize the effective linkage of different transport means and establish an efficient,safe and convenient comprehensive traffic system at the existing traffic supply level.As the exchange station for highway passenger transportation can intrinsically link traffic in and out the cities,its site selection has great influence on the transportation capacity of the comprehensive traffic hinge,overall operational cost and benefit.Therefore,on the basis of the analysis of the factors influencing the site selection for the exchange station,the article makes an analytical study on the site selection for the exchange station by using GIS,making the site arrangement even more reasonable and promoting the better integration of the traffic system.
