Public transport travel time matrices for Great Britain

The data is available on demand, contact ubdc-dataservices@glasgow.ac.uk to request access to the data.

This dataset provides ready-to-use door-to-door public transport travel time estimates for each of the 230,000 2011 Census output areas (OA) in Great Britain (GB) to every other OA reachable within 150 minutes during the morning peak for the year 2023. This information comprises an all-to-all travel time matrix (TTM) at the national level. In addition, the dataset includes two more TTMs at the lower super output area (LSOA) and the data zone (DZ) levels (42,000 LSOA/DZ units in total). These are estimated for two times of departure, specifically during the morning peak and at night. Altogether, these TTMs present a range of opportunities for researchers and practitioners, such as the development of accessibility measures, spatial connectivity or modifiable areal/temporal unit problem analyses, and the evaluation of public transport service changes throughout a day.

This dataset is related to the ‘Public Transport Accessibility Indicators 2022’ (PTAI) dataset (Verduzco Torres and McArthur 2022a, 2022b). The PTAI is openly available from the following links: https://zenodo.org/record/8037156 and http://ubdc.gla.ac.uk/dataset/public-transport-accessibility-indicators-2022/resource/9dc1517f-afd5-4cfe-bbee-5315483fab72. The LSOA/DZ TTM provided in this iteration is comparable to the TTM offered in the PTAI 2022. Please note that despite being published in 2022, the estimates in PTAI 2022 utilized data corresponding to November 2021.
