Live Traffic Predictions for Buses & Trams

More predictable bus rides

Citymapper now knows when traffic is affecting your bus or tram and will update your journey in real-time to reflect it. The app also shows how severe traffic is on your route, so you'll never be caught in an unexpected jam!

How we predict traffic 🤖

Meet Gobot, our super-intelligent robot that analyses all our traffic data. Gobot calculates how traffic affects your journey by studying every vehicle's movement and comparing this with its movement in the past.

Gobot never stops analysing traffic information so that your travel times are always up to date! Thanks to Gobot, bus departure predictions are 35% more accurate and bus arrival times are 12% more accurate than before.

We measure accuracy after the rides are complete, comparing the times we showed in the app to the actual times. Then we compare this to the times we got from transport agencies. Nice one, Gobot.

What's next?

You can now find live traffic in over 200 cities in the app. We can't terminate unpredictable traffic like our bro T-800, but this will help make your ride a little less frustrating.

Some of you might wonder, if Gobot knows all about traffic, what else can it tell me about my bus? Hmm, that's a story for next time... 🤫

Hasta la vista, baby

💚
