Statistical Investigation of the Influential Parameters for Probability Analysis of Ship-bridge Collision Based on AIS Data

摘要

In the calculation of the forces between ship-bridge impacts, theinfluential parameters are needed to be identified. Based on the AIS(Automatic Identification System) analysis on vessel transit path of thebridges over Yangtze River, the influential parameters of the shipbridgecollision of transiting vessel are investigated. These influentialparameters include the ship sailing information and static information,namely yaw angle, velocity, tonnage and the track of ships. For thecorrectness of probabilistic distributions of these parameters, the chisquaretest is applied to modify the probabilistic distributions. Theaberrancy angle and vessel velocity probabilistic models related withimpact forces are established and also verified by goodness of fit test.
