Abstract: A combined algorithm based on multi-sensor information fusion was brought forward. First, statistic estimation method was used to fuse the data from several sensors located at the same site on the link, thus the time average speed of this site could be gotten; then the adaptive weighting average method was used to get the space average speed by fusing these time average speed; finally, the effectiveness of this combined information fusion method was tested using the real data.

Key words: traffic engineering, ITS, information fusion algorithm, statistic estimation, adaptive weighting average method, multi-sensor
