Identification and analysis of ship waiting behavior outside the port based on AIS data

The specific process of the identification method of ship waiting behavior outside the port based on ship AIS data proposed in this paper is illustrated in Fig. Then, the target ship is judged based on whether it is within the port area to distinguish between ship berthing operations behavior and waiting behavior outside the port. When the target ship is within the port area, it is considered as a berthing operation ship; when the target ship is outside the port area, it is considered a ship waiting outside the port. Full size tableIn order to determine the speed of ships waiting outside the port more accurately, this paper proposes a method to determine the speed threshold of ships waiting outside the port based on AIS data. The distribution characteristics of the ship waiting time reflect different ship waiting behavior, that is, the operation behavior in the port and the waiting behavior outside the port.
