Abstract
In order to ensure the safety of navigation of ships at the intersection of traffic flow, the design scheme of the cautionary area in the area of dense traffic flow should be evaluated for risk. This paper constructs a navigation safety evaluation index system for the cautionary area from four aspects: natural environment, traffic environment, ship factors, and management factors. Making full use of the advantages of COWA operator and improved topological cloud theory, the safety level of navigation in the cautionary area is evaluated based on the improved topological cloud model, and the safety evaluation of navigation before and after setting up the cautionary area is carried out with the example of the No.1 cautionary area in Qinzhou Bay. The example proves that the evaluation model is correct and practical, and can be used for the safety evaluation of navigation in the cautionary area.
