Cotral buses with GPS
Cotral connects Rome with towns in every province of Lazio: Rome, Latina, Frosinone, Viterbo and Rieti. Every Cotral bus that transmits its position appears on the map with its line, the route drawn on real roads, the stops still ahead and the delay against the timetable.
Search for the line, the town or the stop name, or use «Stops near me» to see the next departures where you are. Save the lines you use most with the star.
And in Rome
The same area of the map also has the buses of Rome: Atac and the other operators serving the city. Everything is on the page Rome buses in real time.
Where the data comes from
Timetables come from the open data of Cotral and Roma Servizi per la Mobilità, positions from the Cotral buses' on-board system and from Rome's real-time data. Only vehicles that transmit appear on the map: no position is derived from the timetable. Passa il bus is an independent project, not affiliated with Cotral or the Lazio Region.
Frequently asked questions about Lazio
How do I see where my Cotral bus is?

Which provinces does it cover?
All of Lazio, wherever Cotral runs: the provinces of Rome, Latina, Frosinone, Viterbo and Rieti. In Rome there are also the city buses.
Why doesn't my bus appear?
