Public Transport Model Overview

Details of how the public transport model works, including data sources.

Updated over a week ago


  • 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

  • Access the Data Coverage tool here (you will need a TravelTime account for access)
