为了定量分析大型航空枢纽地面交通系统的性能，本文首先阐述了机场可达性的含义和研究机场可达性的重要性。为了评估可访问性，本文使用了一个称为访问成本的新概念，它被描述为金钱。它包括时间、交通费用和与舒适相关的成本三个部分，这是最抽象和难以量化的。为了解决这个问题，本文建议使用一个新的变量来表示“从疲劳和不适中恢复的时间”。“将表示不同类型人的礼仪的重要性系数相乘后，我们可以计算出访问成本的平均值，最终描述了可访问性。为了校正两个关键系数，本文建议使用Logit模型。最后，本文给出了上海浦东机场的简单计算实例，并与另外两个国际机场进行了比较。结论是：舒适度是一个不可忽视的重要因素。与其他国际机场相比，中国机场的可达性需要提高。
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.
