In view of the scientific planning for gates layout and port traffic organization of container terminal in the east operation area of Yantian Port,the simulation and evaluation for port area traffic are studied based on VISSIM.On the basis of the field survey data of Yantian Port area,the design plan of gates and gateways and the design plan of port traffic organization are modeled in three-dimension and simulated at peak hour by the specialized traffic simulation software VISSIM.The rationality of design plans are verified by the quantitative analysis of evaluation indicators.The research provides decision supports for the scientific planning of gates layout and the optimization of port traffic organization in the design process of large-scale and specialized container terminals.
