Abstract: To analyze the performance of the surface transportation system of large aeronautic hub quantitatively，the paper presents at first the meaning of the accessibility of an airport and the importance of researching it．For evaluating the accessibility，the paper uses a new concept called the cost of access，which is described as money． It includes three parts as the time，the traffic fare and the cost related to comfort，which is the most abstract and difficult to quantify．To solve this problem，the paper proposes to use a new variable which means “the time for recovering from fatigue and discomfort”． After multiplying the coefficients of importance which denote the proprieties of different types of people，we can calculate the average of the cost of access，which finally，describes the accessibility． For calibrating two crucial coefficients，the paper proposes to use the logit Model．At last，the paper gives some examples of a simple calculation for the Shanghai Pu Dong Airport，and compares it with another two international airports．The conclusion is: Comfort is an important factor which cannot be neglected．Airports in China need to improve their accessibilities compared with other international ones．

Key words: airport accessibility, cost of access, quantification of comfort, logit model
