可达性是交通分析和规划中一个基本但经常被忽视的概念。文献中出现了三种互补的无障碍观点。第一种是面向约束的方法，最好由Hagerstrand的时空棱镜实现。第二个视角遵循空间互动框架，得出“吸引力-可达性衡量标准”，将目的地的吸引力与所需的旅行成本进行比较。第三种方法衡量运输/土地使用系统给个人带来的好处。本文调和这三个互补的方法，推导出时空的可访问性和效益措施，符合严格的威布尔公理框架的可访问性措施。本研究还开发了计算程序，用于计算网络结构中的这些措施。这提供了现实的无障碍措施，反映了城市交通网络所允许的位置、距离和旅行速度。由于它们的计算负担是合理的，它们可以应用于城市规模使用GIS。
Accessibility is a fundamental but often neglected concept in transportation analysis and planning. Three complementary views of accessibility have evolved in the literature. The first is the constraints-oriented approach, best implemented by Hagerstrand's space-time prisms. The second perspective follows a spatial interaction framework and derives "attraction-accessibility measures" that compare destinations' attractiveness with the travel costs required. A third approach measures the benefit provided to individuals by the transportation/land-use system. This paper reconciles the three complementary approaches by deriving space-time accessibility and benefit measures that are consistent with the rigorous Weibull axiomatic framework for accessibility measures. This research also develops computational procedures for calculating these measures within network structures. This provides realistic accessibility measures that reflect the locations, distances and travel velocities allowed by an urban transportation network. Since their computational burdens are reasonable, they can be applied at the urban-scale using a GIS.
