DSC-14 Public transport access to services

An inability to access services can have negative health and economic effects by increasing social isolation and limiting job prospects. The propeR tool uses multimodal (private and public) transport networks to help others analyse accessibility.

The need

The Welsh Government (WG) need a new accessibility and travel time tool that will be beneficial for a number of ongoing projects and programmes, including:

  • the Welsh Index of Multiple Deprivation (WIMD),
  • access to services domain 2019,
  • The Valleys Taskforce programme,
  • Cadw website and mobile app,
  • Transport policy unit,
  • South Wales Metro programme


The tool will allow WG to use its outputs for multiple projects and programmes. WIMD measurements will immediately benefit from more frequent calculations and real-time monitoring. The code and tool will be published as soon as possible as they are based on open-source tools and data.

Data science

The tool is 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 Shiny and makes extensive use of OpenTripPlanner.


We are working with the Welsh Government.

Code and outputs


  • May 2018 Scoping workshop with Welsh Government and Sustainable Development Goals (SDG) team
  • June 2018 Obtain public transport (bus, rail) data, transform it to required format and validate
  • July 2018 Build interactive tool based on R and Shiny to calculate isochrones, choropleths and extract data
  • August Handover the code to WG for assessing the functionality, outputs and methods used
  • Future Implement additional functionalities based on WG’s feedback
  • Future Handover final tool, publish the tool and write a technical article or blog
