Risk Assessment of Ship Traffic Safety in Port Waters Based on AIS Data

Abstract Maritime safety has always been a matter of great concern to people, and ship traffic safety is one of the most important parts of maritime safety. The port is the starting and ending point of maritime traffic and the connection point of land and sea transportation. Due to the increase in ship traffic, the increase in transport tonnage, and the increase in dangerous goods, the water traffic environment has become more crowded and more dangerous. Under such complex traffic environment conditions, new perspectives should be used to study ship traffic in port waters. Security related issues. Based on the real AIS data of port waters, this paper proposes a new method of ship traffic safety risk assessment by reproducing the trajectory of ships.
