According to the demand of traffic data acquisition and real-time control in ITS, a traffic detection system based on the technology of multi-sensors information fusion is designed. Firstly, two fusion levels based on the characteristics of sapce and time are proposed. Then, the algorithms of spaticial information fusion and temporal information fusion are designed in detail. And the algorithm is optimized based on the characteristics and operation of the algorithm. The simulation demonstrates that the proposed fusion approach can not only save the training time greatly but also improve the accuracy of data processing.
