Impact on Water Traffic Environment Based on ISM Model

The water traffic environment is complex, due to the interaction among factors. To systematically analyze the impacts of the water traffic environment, the factors influencing on the traffic are divided into three major parts including human, ship and environment. Meanwhile, the interpretation structure model (ISM) is used to classify the 11 categories influencing factors into 4 layers. Specifically, the first layer includes navigation aids, operation skills, ship size and ship maneuverability. The second layer is made of waterways/routes, anchorages, and other waters. In addition, berth elements and meteorological hydrological elements are two major parts of the third layer. Finally, the fourth layer is the people's psychological quality and the degree of compliance with relevant rules. According to the layer analyzing results of influencing factors, it is of great significance to maintain the water traffic environment and then help the marine authorities to manage the water traffic environment.
