ABSTRACT The ease of access to sites for activities is referred to as ‘accessibility,’ and the degree of accessibility is inherently the outcome of land use patterns and transportation networks. Therefore, accessibility measures (AMs) are required to evaluate and plan for land use and transportation. Geographic information system tools greatly aid in the calculation of AMs. Since the inception of time geography, an individual’s time constraint has been acknowledged as one of the most important dimensions of accessibility. Thus, the development of theoretically reasonable and practical space-time accessibility measures (STAMs) is a relevant theme in GIScience. By employing a logit modeling framework, this study formulated logsum-type STAMs that have theoretical and practical advantages over existing STAMs. In terms of theoretical plausibility, the proposed STAMs have a behavioral theoretical foundation and satisfy the axioms of AM. In terms of practicality, the proposed STAMs can easily be calibrated with respect to a certain definite time budget. Based on a case study, we demonstrate how the proposed STAMs can be used in practice, with an emphasis on parameter estimation, and we present empirical results that illustrate the plausibility of these STAMs.

可以在确定的时间预算下校准的对数和型时空可达性测量 (STAM)

摘要 进入活动场地的便利性被称为“可达性”，可达性的程度本质上是土地利用模式和交通网络的结果。因此，需要可达性措施 (AMs) 来评估和规划土地使用和交通。地理信息系统工具极大地帮助了 AMs 的计算。自时间地理学出现以来，个人的时间限制已被公认为可访问性最重要的维度之一。因此，开发理论上合理且实用的时空可达性措施 (STAM) 是 GIS 科学的一个相关主题。通过采用 logit 建模框架，本研究制定了对数和类型的 STAM，与现有的 STAM 相比，它具有理论和实践优势。从理论上的合理性来看，所提出的 STAM 具有行为理论基础并满足 AM 的公理。在实用性方面，建议的 STAM 可以很容易地根据某个确定的时间预算进行校准。基于案例研究，我们展示了如何在实践中使用所提出的 STAM，重点是参数估计，并且我们展示了说明这些 STAM 合理性的实证结果。
