Abstract: This paper discusses the data preprocessing of common information platform based on ATMS. First,this paper gives the definition of common information platform based on ATMS and function. Then the paper argues the techniques of data preprocessing of common information platform based on ATMS. Furthermore, the paper advocates the identification of data failure and recover failure data. This paper will provide the principles for data preprocessing of common platform based on ATMS.

Key words: ITS, common information platform based on ATMS, data cleaning, data integration, data transformation, data reduction
