    Abstract
  • In order to evaluate the safety of port traffic environment and determine the weighting of each environment factor, the environment factors data of nine ports were analyzed by factor analysis method, the relationship of port integrated factor scores and port traffic accident numbers was studied, their regression equation was deduced, each factor effect degree on port traffic accidents were determined by each factor coefficient in regression equation.Analysis result indicates that visibility, navigational aids, VTS management degree and traffic separation degree have greater effect on traffic safety, the length of channel and the number of turning points have less effect on traffic safety, which basically reflects the effect degrees of environment factors on port traffic accidents.It is shown that factor analysis method can quantitatively determine the effect degree of each environment factor on traffic accidents, it can be applied to the relationship analysis and assessment of port traffic accidents.
