Research output: Chapter in Book/Report/Conference proceedingChapter or book articleProfessional


Increased ship traffi c involving large tankers and passenger ships increase the risk of accidents. An indicator for the probability of a collision accident can be acquired by assessing the number of near miss situations. This study shows that these situations can be identifi ed in a neutral and automatic manner by analyzing ship position data gathered through the Automatic Identifi cation System (AIS). The method is suggested to be used as one parameter when measuring the effects of actions taken to reduce the probability of collision risk in open water areas.
