To ensure the safety of loading and unloading operations，the design of automated container terminals focuses on how to separate the flow of internal automated vehicles from the flow of external trucks.Water to water transshipment is the main collection and distribution model in many container terminals in the world.The ratio of water to water transshipment is different，the ratio of containers entering and leaving the port on the seaside and landside of the terminal is different，and the requirements for the horizontal transportation system in the port are also different.In view of the limitations of the existing traffic diversion technology schemes in automated container terminals on the adaptability of ratio of water to water transshipment，we propose a new traffic diversion technology with high and adjustable ratio of water to water transshipment in automated container terminal，and analyze the adaptability to water to water transshipment ratio adjustment of the process，which can provide reference for the planning and construction of similar automated container terminals.
