This paper reports on a study of bridge openings that serve as waterways, in view of the analysis of ship collision accidents. For the purpose of this study, cases of ship collision accidents were collected and investigated. The authors conclude that the probability of ship collision is increased in cases where the main span is less than 2 or 3 times the ship length, and in cases where the straightaway is less than 8 times the ship length. These results are very similar to the figures of the ship avoidance area in marine traffic engineering.
