Abstract: In order to study the passage capacity of the seaport and explore the service level of the channel, the cellular automata theory is used to discretize and model the main channel of the seaport, and the movement rules of the cell in the channel are processed in sections. In addition, this study focuses on the existence of a traffic "warning zone" in the curved channel section. The ship motion rules of the straight channel section and the curved channel section are respectively constrained, through simulation experiments, the vessel traffic flow of the channel and the maximum ship passing capacity of the channel are obtained, the saturation of the channel is calculated and the service level of the channel is evaluated. The simulation results show that the model can accurately reflect the ship operation in the channel and evaluate the current and long-term service level of the channel.
