对无障碍的概念有不同的解释，如“接近场所”、“接近活动”以及最近的“便于参加活动”。随着这些定性的解释，也有各种定量的无障碍定义。本文件表明，许多拟议的无障碍定义实际上可以汇集在一起，形成一系列的无障碍措施。这些措施在制定过程中所包含的因素以及对行为的解释程度方面各不相同。现有的无障碍措施在一个主要方面存在不足。也就是说，他们假设，对于任何一种可达性的措施，只有一个旅行的起源。因此，在估计区域内某个点的可达性时，假设所有有助于该点可达性的潜在行程都从该点开始。鉴于大量证据表明...
The concept of accessibility has been variously interpreted as being the “nearness to places,” the “nearness to activities” and more recently the “ease of participating in activities.” With each of these qualitative interpretations, there has also been a variety of quantitative definitions of accessibility. This paper shows that many of the proposed definitions of accessibility can in fact be gathered together to form a spectrum of accessibility measures. These measures differ with respect to the factors included in their formulation and their degree of behavioural interpretation. Existing measures of accessibility are shown to be deficient in one major aspect. That is, they assume that for any one measure of accessibility there is but one origin of trips. Thus, in estimating the accessibility of a point within a region it is assumed that all potential trips, which contribute to the accessibility of that point, start from that single point. In view of the considerable amount of evidence demonstrating the ...
