Welsh Access to Buses Indicator: Administrative Zones

This purpose of this website is to provide insight into the availability of public bus services across Wales. It presents an interactive map displaying a detailed and meaningful measure of public bus service levels as experienced by Welsh residents. At the core of this website are over 98,000 postcode level scores of public bus provision, recorded in 2019, 2021, and 2023. These "WABI" sores represent a robust, reproducible, and data-derived measure of bus availability. Individual postcode scores are seen directly and may be queried when the map is zoomed to its maximum level.

Postcode level detail becomes overwhelming at broader scales, so as the map is zoomed out the WABI scores are aggregated and mapped within the hierarchy of administrative zones used by the Office for National Statistics for Census data reporting. As the map is zoomed out, scores reporting the average number of bus departures per hour may be queried for Output Areas, then Lower Layer Super Output Areas, then Middle Layer Output Areas, and finally 2022 Parliamentary Constituencies.

By providing information on bus service levels over three dates and for various timeframes of interest (e.g. daytime, evening and weekends) the website aims to a develop a better understanding of bus transport provision in and across Wales, helping users to identify where inequalities in provision may be present and highlighting where future improvements may be most needed.
