Study On The Function Of MTR Underground Space And Potential Commercia Space

With the expand of city, transient population and motor-driven vehicles are also on the rise. As the gradually intense contradiction between the traffic demand and supply, to alleviate the traffic congestion, traffic accidents and heavy pollution in megalopolis and resolve traffic problem efficiently, especially the sharp shortage of land is a common problem in megalopolis. More and more traffic staff recognized root of the problem that give priority to the development of public traffic, which is on the basis of track traffic system.Composing mainly of public transport and passenger transport in order to enhance the traffic capacity as well as promote the development of underground space, and further stimulate regional economy.As one of the important central city in southwest china, Chengdu has already become a megalopolis city. During the development of Chengdu, chance and challenge require scientifical plan on transport system. It is very necessary to create a high-speed track traffic system to meet the demand of sustainable development of a modern city.Because restricted by self-condition, Chengdu can't satisfy the transport requirement now and future with limited central space. As early as the end of 1980's, according to the city's programs, Chengdu government set up the cross frame constituting the high-speed track traffic system which greatly effect the development of city. track even determinate how to development.As the diverse functions of underground space and rationally plan on transport transfer among vehicle, non-vehicle and private transport , which can help us to decide the distribution and function of commercial space.Bringing the principle of traffic distribution, the author analyzed and predicated the traffic transfer with matrix model. After researching the current situation of subway overseas and taking the development and plan for south section No.1 track of Chengdu subway as example, the author lay particular emphasis on the function and commercial development of the underground space.
