| Transport hub plays a key role at the integrated transport system. Because it is the meeting point of a few lines or a variety of transport modes, so there often have a lot of issues, and the plug is much more than other regions within and around the transport hub. So, Study on the transport hub make great significance for the integrated transport. This paper uses the existing theory of transport hub and road network theory, takes Kirchhoff's law in the research of the transport hub, to explore a new method in the research of the transport hub. The main work is in the following.In this paper, firstly, I analyze transport hub from both theoretical and practical aspects of building. In the theory part, I introduce the transport hub's concept, role and classification. I analyze several research theories of the transport hub and the defects of these theories. In the practical aspects of building part, I introduction the design specifications of three types of integrated transport hub, analyze traffic how movement of traffic flow in the transport hub, point out the existing deficiencies in the building of transport hub. Secondly, I demonstrate that bringing Kirchhoff's law into transport hub study is a right idea. I Contrast the transport network and circuit network. What is the same and different between them. And then I analyze that how can I take the Kirchhoff's law into transport hub Study. On this basis, the article gives the method to use the Kirchhoff's law in transport hub research. I introduce the mathematical tools needed, and then give a specific model. I analyze the scope of model application and how to use the model. The model is based on Maximum flow/Minimum cut Algorithm which is used in network capacity study. Used this model you can get the largest capacity of the transport hub, and find out the key points which decision the capacity of transport hub. Finally, I sum up the article and look at the prospects of this research in the future. |
