Abstract
To present an analysis and application method of ship traffic flow considering navigation rules in narrowing channel, which can make a reasonable judgment for decision makers to improve navigation efficiency and ensure navigation safety. In this paper, the relationship model between narrowing channel and ships is analyzed from the perspective of navigation. Based on the constraint condition of navigation safety domain, the navigation rules are formulated for different positions of channel, and the mutual influence of ships at the narrowed position of channel is analyzed emphatically. The establishment scheme of traffic flow model of narrowing channel with navigation safety distance is put forward by using cellular automata algorithm. According to the measured data, the correctness of the ship traffic flow model of narrowing channel is verified. The experimental results show that the relative error rates are between −2.29% and 10.89%, which indicating that the method can better conform to the actual ship traffic flow characteristics of channel narrowing and has strong application value.
