Risk Evolution Analysis of Maritime Traffic Accidents in Coastal Areas of China

The study of water traffic accidents can help to understand the causes and mechanisms of water accidents, so as to help reduce the occurrence of water accidents and improve the level of maritime safety management. Based on the investigation report of China’s coastal water traffic accidents, this study analyzes the risk evolution of water traffic accidents based on accident causation theory and complex network theory, and discusses the risk evolution characteristics of China’s coastal water traffic accidents from the stages of accident latency, diffusion and occurrence in combination with network topology characteristics. The research results show that ship collision is the main accident type of coastal water traffic in my country, and improper operation and human error are the key causes of accidents; accident evolution has obvious characteristics such as short transmission path and strong randomness, and the risk factors are interdependent; many Node failures are more likely to cause the system to crash, resulting in accidents.
