Great Britain Accessibility Indicators 2023 (AI23)

Overview

Accessibility indicators measure the ease of reaching valuable destinations (Levinson and Wu 2020). The current dataset, Great Britain Accessibility Indicators 2023 (AI23), provides small-area indicators to key services such as health, education, employment, and urban centres.

This dataset is an updated and expanded version of the the Public Transport Accessibility Indicators for Great Britain 2022 (PTAI22) dataset (available at: https://zenodo.org/records/8037156, and described at: https://www.nature.com/articles/s41597-023-02890-w) (J. Rafael Verduzco Torres and McArthur 2024).

In particular, the AI23 dataset provides a suite of ready-to-use accessibility indicators by public transport,bicycle, and on foot to employment, general practices (GPs), hospitals, pharmacies, parks and gardens,primary and secondary schools, supermarkets, main urban centres, and urban sub-centres. These indicatorsare available for 42,000 small area units across Great Britain (GB), specifically at the Lower Super OutputArea (LSOA) level in England and Wales, and the Data Zone (DZ) level in Scotland. It includes active modes, specifically walking and cycling, in addition to public transport.

A full data descriptor is available here (URL: https://osf.io/preprints/socarxiv/qb9j4_v1) (Verduzco Torres & McArthur, 2024b).
