大容量快速轨道交通(地下铁道、高架轻轨以及独轨交通等)以其快速便捷的优点成为中国未来城市交通发展的主要方向之一,是构成中国未来立体城市公共交通网络的主体。预计在未来10年内,中国将集中全球近3/4的轨道交通的投资。目前全国各大城市已经进入大力发展轨道交通系统的高潮期,北京、上海、广州、南京、深圳的建设正如火如荼地在进行,另外还有十多个人口超百万的城市在“十五”期间将上轨道交通建设项目,例如上海在今后5年中,市政府计划每年平均建造轨道交通线路20km以上,个别年度将达到40km。轨道交通的迅速发展带动了对各种运营支撑系统的需求和更高的功能要求。而一个可靠、可扩展、独立的通信基础网络是其信息基础建设中的重要组成部分,是保证轨道交通系统正常运营和管理的综合性信息传递平台,是其他支持系统的基础。
Mass Rapid Transit (metro, elevated light rail and single-track traffic, etc.) has become one of the major directions for the future development of urban transport in China due to its quickness and convenience. It constitutes the mainstay of the public transport network in China’s future three-dimensional city. It is estimated that in the next 10 years, China will focus on nearly 3/4 of the global rail transit investment. At present, major cities in China have entered a climax of vigorously developing the rail transit system. The construction of Beijing, Shanghai, Guangzhou, Nanjing and Shenzhen is in full swing. In addition, there are over 10 cities with over one million in population in the “10th Five-Year Plan” During the construction of rail transit projects, such as Shanghai in the next 5 years, the municipal government plans to build an average of more than 20km of rail transit lines each year will reach 40km in individual years. The rapid development of rail transportation has driven the demand for various operating support systems and higher functional requirements. A reliable, scalable and independent communication infrastructure network is an important part of its information infrastructure. It is a comprehensive information delivery platform that ensures the normal operation and management of the rail transit system and is the basis for other support systems.
