高速公路采用ITS的必要性

The Necessity of ITS Adopted in Expressway

交通是国民经济的基础产业 ,是社会发展和人民生活水平提高的基本条件。交通运输的发达程度是衡量一个国家现代化程度的标志之一。随着高速公路建设的发展 ,如何高效、安全地使用高速公路成为亟待研究的问题。单纯地依靠修建更多的道路、扩大路网规模 ,已不能解决日益增长的交通需求 ;运用高新技术 ,如现代信息与通讯技术等手段 ,来改造现有的道路运输系统及其管理体系 ,可以大幅度地提高路网的通行能力和服务质量。智能交通系统 (ITS)是交通运输发展的方向 ,也是解决交通运输瓶颈的重要措施。文章通过详细的数据 ,首先分析了我国高速公路发展的现状 ,然后分析了国外高速公路建设的经验 ,最后以四川省联网收费项目为例 ,阐述了中国高速公路发展对智能交通系统的需求。

With the improvement of Chinas expressway, how to use expressway economically and safely has became an important problem. Setting up more roads simply, and extending the road net scale can not meet the increasing transportation need. Application of Hi tech, e.g. modern information and communication technique, to reform the current road system and its management system, can significantly increase the traffic capacity and the service quality of road net. Intelligence transportation system (ITS) is a direction to transport development, and also an important measure to solve the transportation conveyance bottleneck.This thesis, based on the detailed data, analyzed present developing condition of Chinas expressway first, then analyzed the overseas expressway development experience, and finally expatiated the necessity of ITS used in Chinas expressway by taking the Sichuan Province ITS project as an example.
