An inability to access services can have negative health and economic effects by increasing social isolation and limiting job prospects. The Data Science Campus (DSC) worked with the Welsh Government to produce a R package called propeR, which uses multimodal (private and public) transport networks to help others analyse accessibility.

The Welsh Government needed a new accessibility and travel time tool to benefit a number of ongoing projects and programmes, including:
- the Welsh Index of Multiple Deprivation (WIMD),
- The Valleys Taskforce programme,
- Cadw website and mobile app,
- Transport policy unit,
- South Wales Metro programme
This new tool allowed Welsh Government to use its outputs for multiple projects and programmes. WIMD measurements will immediately benefit from more frequent calculations and real-time monitoring.
The tool was based on open-source tools and data. We gathered public transport (bus, rail) information and transformed it to General Transit Feed Specification (GTFS) format. The tool is built in R and makes extensive use of OpenTripPlanner.
We are working with the Welsh Government.
