GIS在城市轨道交通中的功能分析

摘要

It is a new trend that GIS technology is used in urban rail transit. With the use of GIS technology, the rapid response capabilities and comprehensive coordination control capabilities of urban rail transit can be improved. In this paper, the functions of the geographic information systems used in urban rail transit construction and operation phases were analyzed. First, the applications of GIS to urban rail transit in domestic and foreign were introduced. Then, the functions of GIS in rail transportation construction, city track traffic scheduling command and urban track transport emergency action were analyzed. Finally, based on the function analysis of GIS the trend of GIS used in urban rail transit was predicted. It was concluded that geographic, information system in urban rail transit should be multi-function, vertically integrated, multi-information technology integration and visualization.%地理信息系统技术应用于城市轨道交通成为一种新的趋势，它能够提高轨道交通管理的快速反应能力和综合协调控制能力。本文针对地理信息系统应用于城市轨道交通建设、运营等阶段的功能进行分析，首先对地理信息系统在国内外轨道交通中的应用进行简介，再着重对地理信息系统在城市轨道交通建设、城市轨道交通调度指挥以及城市轨道交通应急处理中的功能进行总结并加以简单的分析，最后基于 GIS 在城市轨道交通中的功能分析，对 GIS 在该领域的发展趋势进行预测，得出地理信息系统在城市轨道交通中的应用应朝多功能综合一体化、多信息技术融合及三维可视化方向发展的结论。
