Through the analysis of characteristics of Yantian Port transportation,it is found that the main reasons for the mixed traffic and the tension between port and city is the small land depth restricting the port operation area,the seriously unbalanced distribution ratio of port-evacuating traffic system relying on highway transportation,the insufficient port supporting facilities and the relatively old infrastructure.It is proposed to improve the role of Pingyan railway by increasing the proportion of sea-rail intermodal transportation,strengthen infrastructure construction and make full use of intelligent management,and study the optimization of the possibility of container underground logistics transportation.Practice has proved that these methods have a significant effect in the optimization of the port-evacuating traffic,they can improve the port-evacuating traffic system,enhance the efficiency and the competitiveness of the port area and reduce the contradiction of caused by the congestion of port traffic.The research results can provide reference for the traffic optimization of the container port area with a small land depth.
