大数据技术在城市轨道交通中的应用

Application of Big Data Technology in Urban Rail Transit

随着城市轨道交通事业在我国的快速发展,信息化技术在轨道交通领域得到了深入的应用,从而使轨道交通行业的信息化水平得到了长足的进步。与此同时,轨道交通系统在日常运营过程中积累的大量数据也呈现出爆发性增长的趋势。面对海量数据,亟需建立一套高效的数据管理与应用体系。梳理和介绍了数据管理技术发展到大数据的历程,分析了技术发展的必然性,对轨道交通数据的特征进行了提取,得出了轨道交通数据是符合大数据特征的工业大数据的结论。最后,结合实践经验对轨道交通大数据的应用场景进行了总结和展望。

With the rapid development of urban rail transit in China,the information technology has been deeply applied in the field of rail transit,and the information level of rail transit industry has made great progress.At the same time,a large number of data accumulated in the daily operation of rail transit system also show an explosive growth trend.To deal with these massive data,it is urgent to establish an efficient data management and application system.The development of data management technology is introduced and the inevitability of technology development is analyzed.According to the characteristics of rail transit data,it come up with the conclusion that rail transit data are industrial big data conforming to the characteristics of big data.Combined with practical experience,the application scenarios of rail transit big data are summarized and prospected.
