Prague has an excellent public transit system, but there still are delays. An online map shows the exact location of all public transit vehicles in real time, so you can decide if it is worth waiting or making alternative plans. The function will likely soon be added to the PID Lítačka application. People in Prague and Central Bohemia can see exactly where each metro train, tram, bus, or ferry is on the route, how late it is, and check the timetable. The map can be filtered by route number, type of vehicle, or even vehicle registration number.
