At first, we obtained AIS (Automatic Identification System) information from passing vessels, then after, analyzed the lateral distributions of vessel tracks and estimated the mean and the standard deviation for the distance away from bridge center, the passing course and the passing speed. The analysis results of track distribution for the distance away and the passing course are shown as normal type, otherwise the speed distribution shown as two kinds of different normal type. In addition, we testified that the usefulness of estimated parameter values through the relative comparison between the track distributions and it's normal probability distributions.Key words :Mokpo harbour bridge, vessel-bridge collision, vessel track distribution, statistical parameter, normal distribution† : , jbyim@mmu.ac.kr 061)240-7170* , badajigi75@mmu.ac.kr 061)240-7137
