Study on the Temporal and Spatial Distribution Characteristics of Aquatic Traffic Accidents

Abstract The study of the characteristic of aquatic traffic accidents is significant for avoiding accidents effectively and guiding the supervision of water traffic safety and the search and rescue of water accidents. In this paper, the temporal and spatial characteristics of aquatic accidents from the aspects of accident occurrence and accident consequences were studied. The results indicated that the total number of verified distress incidents has significant temporal and spatial distribution characteristics; the number of verified distress incidents in coastal areas is significantly higher than that of inland rivers; the main causes of water accidents include collisions, stranding, fires and windstorm, all of which have a significant temporal distribution. In terms of accident consequences, the number of general danger is significantly higher than that of other levels of risk, and there is a significant temporal distribution characteristics on four danger levels. The main types of ships in distress are transporting ships, agricultural vessels, fishing boats and official ships. The number of transporting ships and fishing boats both fluctuated greatly in some months; there was no difference on the temporal distribution for the number of agricultural vessels and official ships in a year. There is no significant linear relationship between the number of distressed people and ships; the number of people in distress on the four types of ships all showed a certain time distribution characteristics; the number of deaths and disappearances in the main rivers rose sharply in June. By analyzing the temporal and spatial distribution characteristics of accidents and their consequences, this paper provides a basis for the relevant authorities to optimize the prevention and control of water accidents, the layout of water search and rescue forces and the timeliness of target searches.
