Hello. How can we help you?

How does the Public Transport model work?

Overview of how we build our own proprietary public transport models used for creating isochrones, routes, and travel time matrices


  • We have our own proprietary public transport routing models, built by us from the ground up
  • The models traverse every possible route based on public transport timetables and data gathered from a huge list of public transport agencies
  • Built for true human routing, we incorporate our own walking model to provide door-to-door journey times that represent how people actually travel
  • All combinations of public transport methods are included - bus, coach, train, underground, tram, etc


Where the data comes from

  • Data is at the heart of what we do, and we have a dedicated data team whose job it is to source complete, accurate, up-to-date public transport timetable data, and incorporate it into the public transport model
  • We pull data out of every imaginable source - where GTFS data doesn’t exist, but we can find timetables in other formats, we create our own GTFS data
  • The data is updated at least every two weeks, so it is always right up-to-date
  • We are fully transparent about what data we have and where, including providing an interactive online tool to explore the data in detail:
