Accessibility and its many dimensions: why ‘geographical accessibility’ alone is not enough

Petteri Muukkonen 

In geography, ‘accessibility’ is often used as shorthand for geographical accessibility (distance, travel time, travel cost, and related spatial measures). Yet accessibility carries different established meanings across disciplines, so geographers should name geographical accessibility explicitly when that is what is meant. This discussion paper argues that geographical accessibility is only one dimension of a broader, multidimensional accessibility, and that conceptual precision matters for research quality and equality-oriented planning. To address a recurring measurement bias, in which what is easy to quantify can dominate what is studied, the paper proposes a practical ten-dimension framework for analysing services and activities. The dimensions are: geographical, physical/technical, temporal, informational, economic, administrative, cultural-attitudinal, skills-related, mental, and social accessibility. By treating geographical accessibility as one dimension among others, researchers can better identify where barriers accumulate, for whom accessibility fails, and why ‘nearby’ does not always mean ‘possible’.
