How to see where your bus or tram is right now: a guide for 32 Polish cities

7 November 2026

Where is my bus? How to see trams and buses on a live map, check delays and departures from a stop in Kraków, Warsaw, the Tricity and other Polish cities.

The display at the stop has said “3 min” for five minutes and there is no bus in sight. Instead of guessing, you can check where it really is. Most big Polish cities publish their vehicles' positions as open data; all you need is an app that shows them.

Quickest: the live map

Open Wiesz Kiedy in your browser or the Android app and choose your city.
Go to the Live tab. Every vehicle is a badge with its line number; the arrow shows its direction.
Type a line number in the filter (e.g. “52”) to keep only that line's vehicles.
Click a vehicle to see its route, delay and the times at its next stops.

Every line page also has a Where is it now? button that opens the map with just that line.

When you want to know when it reaches your stop

In the Departures tab, type the stop's name or click Near me. The board shows the next departures from all platforms of the stop, refreshes every 20 seconds and says for each one whether the vehicle is on time or late. When a time is marked “scheduled”, the operator gave no live data for that trip and the time comes from the timetable.

Where does the data come from?

Vehicle positions are published by the operators and transport authorities, usually in the GTFS-Realtime standard. Wiesz Kiedy fetches them every few seconds, matches them with the timetable and works out the delay. In cities where vehicles have no transmitters or the operator does not share the data, we show departures from the timetable. The full list of sources is on the Data sources page.

Which cities does it work in?

Live vehicles are available in Kraków, Warsaw, the Tricity, Wrocław, Poznań, Łódź, the GZM metropolis, Lublin and Szczecin, among others. All 32 cities are on the timetables list.

Three tricks that save time

Set the start to “My location” in the planner: Wiesz Kiedy works out the walk to several nearby stops and picks the one that really gets you there sooner.
Watch “Leave in X min” next to the planner's results: that is when to leave home, with the vehicle's delay already counted.
Check a line's punctuality on its page before an important trip: some lines are regularly late at the same time of day.
