This paper integrates and extends many of the concepts of accessibility deriving from Hansen’s (1959) seminal paper, and develops a theory of access that generalizes from the particular measures of access that have become increasingly common. Access is now measured for a particular place by a particular mode for a particular purpose at a particular time in a particular year. General access is derived as a theoretical ideal that would be measured for all places, all modes, all purposes, at all times, over the lifecycle of a project. It is posited that more general access measures better explain spatial location phenomena.

迈向通行的一般理论

本文整合并扩展了许多源自Hansen（1959）开创性论文的可访问性概念，并发展了一种访问理论，该理论从越来越普遍的特殊访问度量中进行了概括。现在，在特定年份的特定时间，通过用于特定目的的特定模式，测量特定位置的访问权限。通用访问是作为一种理论理想而得出的，它将在项目的整个生命周期中的所有时间，所有模式，所有目的，任何时间进行度量。假定更一般的访问措施可以更好地解释空间定位现象。
