Abstract: The traffic sensor data screening of intelligent transportation system(ITS) was discussed and the data flow exchange between data screening unit and other system of Traffic Information Center(TIC) was described.The content and general procedure of data screening were introduced.The checking condition of data reasonableness and consistency in different traffic conditions were analysized.Data screening can identify the error data from the raw sensor data,and assure the reliability of input information to traffic related functions.

Key words: ITS, data processing, data screening
