摘要
在ATMS中,信息是最核心的内容,系统的各项功能都是以信息的应用为中心展开的。为了在ATMS中保证使用数据的质量,提高信息资源的利用率,降低信息资源的周期损耗,提高系统的处理效率,减少系统的开销,采用数据清洗技术,建立了适合ATMS系统信息需求的数据清洗框架,实现对现有采集到的道路安全信息数据进行高效率的优化处理,使输入到ATMS系统的信息数据能保证系统做出高质量的决策,进而提高系统的运行效率。
In ATMS（Advanced Traffic Management System）,information is the most core content.The various functions of the system are based on information in the application as the center spread.In order to guarantee the quality of the data used in ATMS,to improve the utilization of information resources but reduce the loss of information resources cycle,to improve the processing efficiency of the system but reduce the overhead of the system,this paper uses the data clean technology to establish a data clean framework,which has suited the ATMS＇s demand of the information data cleaning and realized the high-efficiency optimized processing of the road safety message data gathered currently.As a result,The data input into the ATMS can ensure the system make hign-quality decisions.Thus,the system＇s operating efficiency can be promoted.
