In order to utilize the AIS for vessel traffic evaluation, we have investigated the present condition and the characteristics of the AIS data from the actual observation and have reported that in our previous papers. We have also reported that the details of ship's behavior could be grasped from some of the AIS data. In this paper, from the viewpoint of using the AIS data for the vessel traffic survey, we examine the characteristics of the position error by the comparison of the Radar and AIS positioning results. The results are as follows. 1. The error in length is larger than that in width and shows periodic fluctuation. 2. A few ships have larger bias errors in length and it would be caused by the GPS antenna position around the bow. 3. The standard deviation with the error in length shows positive correlation to the average speed or the length of ship.
