Development of analytical method for finding the high risk collision areas

The traffic condition has been analyzed by models that are based on Gas model and Obstacle Zone by Target (OZT) by using 1 year AIS data for Tsunami measure. By applying Gas model based method, it is possible to analyze the area in terms of ships' relative angle, size, speed and density. The OZT is originally developed to show the collision zone on the target ship's course. By using this method to the marine traffic analysis, high possibility of collision areas are estimated. Moreover, ships that courses are heading to OZT are identified and studied their position and how long they proceed course heading to OZT.
