The turnover time of outbound container trucks is one of the main indicators to measure the production and service capacity of a terminal. Aiming at the problem of low operation efficiency of the collection and distribution of the automated terminals，this paper studies the operation modes of the outboard container trucks and the factors affecting the turnover time of the outboard container trucks，and summarizes the factors affecting the average turnover time of outbound container trucks into ten categories，such as the number of containers in the collection and distribution，the inventory of the yard，the busyness of the seaside operation，the time arrangement of the collection port，and the collection and distribution capacity of the yard. The results show that coordination of port collection time can avoid centralized pressure at stations；balancing sea and land side production can reduce operational conflicts；strengthening the management and control of collection and distribution at surrounding stations can reduce traffic jams at gates；strengthening inter-departmental coordination can improve system and equipment stability and other measures to effectively reduce the turnover time of outbound container trucks.
