Abstract

The invention belongs to the technical field of traffic transportation station planning design and management, and relates to a method for optimization design and traffic organization micro-simulation of a container terminal gate buffer area. Quantitative bases are provided for the layout design of container terminal gate buffer area facilities, such as the number of gate channels and buffer area scales, quantitative bases are provided for the effective utilization of the gate channels and the buffer area in the dock operating and management process, a time table showing when a ship arrives at a port and leaves the port is used as a boundary condition, and the simulation experiment is carried out on a container truck queuing system in front of a container terminal gate. To achieve the aim, according to the technical scheme, the method for the optimization design and the traffic organization micro-simulation of the container terminal gate buffer area comprises the following steps of the selection of cells; the components of the cells; the operation of a cellular automaton; an entrance cellular automaton model, wherein (1) the cells are initialized, and (2) the cellular automaton is operated; an exit cellular automaton model; wherein (1) the cells are initialized, and (2) the cellular automaton is operated. The method is mainly used for traffic transportation station planning design.

Description

technical field [0001] The invention belongs to the technical field of transportation station planning, design and management, and specifically relates to the optimization design of the gate buffer zone of a container terminal and a microcosmic simulation method of traffic organization. technical background [0002] At present, there are very few studies on the buffer zone of the container terminal gate at home and abroad, which are mainly divided into the following aspects: First, the optimization design and management of the buffer zone of the port gate are carried out by establishing the analytical model of the queuing theory of the buffer zone of the port gate through relevant assumptions . For example: Morais and Lord proposed the famous Terminal Appointment System (TAS) in 2006. Through the information interaction between the front terminal, the rear yard and the cargo owner, the collection trucks in the peak period of the collection and distribution port can be reason...

AI Technical Summary

Problems solved by technology

[0004] (1) At present, many studies on the buffer zone of container gates are based on the macro theory and the analytical model of queuing theory is established. The research methods proposed only stay at the macro level and cannot reflect the complex relationship between various factors in the traffic flow of the gate buffer zone. Non-linear relationship, the research object cannot be analyzed in detail, and the expected effect is often not achieved

[0005] (2) Although many softwares for the simulation research of the container terminal gate buffer zone are relatively easy to operate and the interface is easy to interact with, the decision-making behavior of the decision-making agent in the simulation model cannot be defined during the research process, and the research is also difficult. not reach the micro level

Therefore, these methods have shortcomings such as not being precise enough, and the model description cannot fit the reality.
