Abstract: This paper presents logical structure, basic functionality, inscape, and organization proposal of database of the common information platform based on ATMS. Firstly the importance of the common information platform based on ATMS and the context of the fundamental traffic information provided by the common information platform are .expatiated. Secondly, the common information platform is divided into three structural levels according to its logical structure. The functions of the common information platform are introduced, and the relationships of these functions are showed. Thirdly, key technologies, such as data fusion, data warehouse and data mining, are introduced and the factors are analyzed which should be considered when the common information platform is collecting data. At last, database organization of the common information platform based on ATMS is analyzed and discussed emphatically according to the distributed database. Two basic methods of building the common information platform are put forward, with the advantages and disadvantages of the methods discussed.

Key words: ITS, ATMS, the common information platform, distributed database
