This thesis, concentrates on marine collision risks of the area divided by cells. Using a gas molecular collision calculation model, a collision risk model is proposed. Collision risk is estimated by relative angle, relative speed, and ship’s density in the cell. For one week, Automatic Identification System (AIS) data was collected and analyzed on the Busan North Port area. The results indicate a high-risk area at the sea route connection point in Busan North Port .It also shows that twilight is the time of day when most collisions occur .This means that the area is high risk due to the number of collisions and other dangerous factors related to twilight . Although there is still need to consider other risks such as grounding risks, the results of this study are useful to for plotting a risk map for the port.
