This study analyzed the occurrence of maritime traffic accidents in the six congested waters of Japan and found that its process was stationery and no strong correlation was detected among these six waters. Based on these findings, a statistical test was conducted to detect the effect of the vessel traffic services (VTS) on the occurrence of a navigating vessel and maritime traffic accident on four waters (Tokyo Wan, Bisan Seto, Kanmon Kaikyo and Osaka Wan) from 1975 to 1997. While the introduction of VTS significantly reduced the number of accidents (5% level) without any delay at the latest installation site (Osaka Wan, 1993), a delay of 14-28 months was found to give a statistically significant result (10% level) at the remaining three sites. This delay can be considered a demonstration period to get used to the function and process of VTS.
