When is my bus coming in Rome?
Open the map, search for the line number (for example 64, 75 or 913) or the stop name (for example Termini or Piazza Venezia) and look at the departures board: each trip shows the updated time with the real delay, calculated from the vehicle's position along the road. Tap a bus on the map to see where it is coming from, the next stop and all the stops still ahead.
With «Stops near me» the map shows the stops around you and the next departures. Save the lines you use most with the star: they stay on your phone.
Which buses are on the map
The buses of Atac and the other operators running services in Rome (Troiani, BIS, ATR Mobility, Tuscia), plus the Cotral buses coming into the city from the rest of Lazio. Only vehicles that transmit their position appear: no dot is derived from the timetable. Trams and the metro do not transmit their position and appear only in the stop timetables.
Where the data comes from
Timetables, stops and positions come from the open data of Roma Servizi per la Mobilità (GTFS and GTFS Realtime), the same data transport apps use worldwide. For Cotral, positions come from the buses' on-board system. Passa il bus is an independent project: it is not the official app of Atac or Roma Mobilità, and the official timetables remain those published by the operators.
Frequently asked questions about Rome
How do I know when the bus is coming in Rome?
Open Passa il bus, search for the line or the stop and look at the departures board: times take the bus's real position into account. It works in your browser at mappa.passailbus.it, choosing Lazio from the menu at the top, or in the free app for iPhone and Android.
Are Atac buses on the map?
Yes. Atac buses and those of the other operators serving Rome appear with position, next stop and delay, whenever the vehicle transmits its GPS.
