Access terminology is evolving since its inception by Hansen in 1959. Accounting accessibility is central to multiple disciplines such as geography, transportation, health, economics, social sciences, etc. Developing indicators to measure access is a common practice and usually favor specific dimensions of access based on application. Although measuring accessibility and developing related indicators is a common practice, there are missing links in the indicator development, planning process, its implementation and related policy-making. Due to many available indicators, each differing in context, the practicality of implementation and their transferability is generally lost. Current work focuses on extracting commonalities between indicators and understanding how the contextual focus of indicators’ have changed over time to measure access. Requirements for improved access related policies, developing realistic measures and future research directions based on gaps in the identified access measures are suggested.

自1959年汉森（Hansen）创立以来，访问术语一直在不断发展。会计可访问性是地理，交通，卫生，经济学，社会科学等多个学科的核心。制定衡量访问的指标是一种常见做法，通常偏爱访问的特定维度基于应用程序。尽管衡量可访问性和制定相关指标是一种常见的做法，但是在指标制定，规划过程，其实施和相关政策制定中缺少链接。由于有许多可用的指标，每种指标在上下文上都不相同，因此实施的实用性及其可转让性通常会丢失。当前的工作着重于提取指标之间的共性，并了解指标的上下文焦点如何随着时间的推移而发生变化以衡量访问量。
