Study On The Reasonable Mode Of Taxi Based On The Balance Of The Supply And Demand

Along with the development of the economics and the enhancement of peoples' lives, the taxi becomes so popular as a transportation with convenient and comfortable service according to the passenger's demand. The statistical data demonstrated that the national taxi has grown from 111,000 in 1990 to 904,000 in 2004 by 16% per year. Therefore, it appeared the unbalanced phenomenon between the supply and the passenger's demand of the taxi quantity in many domestic major and medium cities. The direct performance is that the unloaded ratio is much higher, and it makes the taxi traffic waste of the path resources, intensify the traffic congestion and the air pollution.Firstly, based on the analysis of the taxi definition and features, this article elaborated on the basic situation of the taxi, including the external environment, the management of the taxi. Secondly, it summarized the factors which influenced the taxi passenger's demand and supply, it also described the methods to quantify the taxi passenger transportation. Finally, considering the factors that influenced the parameters of the taxi reasonable scale model, we can establish the taxi reasonable scale mode which was based on the balance principle on the supply and demand. It took the taxi effective travel course as a balance point. On these bases, we can adjust the model and analyze the mode in order to take the travel data of investigation of Xi'an inhabitant as the example to prove its convenience. This research had the significant meanings on the taxi resources optimization, the coordinated operation of the city public traffic system, and the sustainable development of the whole city's traffic system.
