Buses in Prague
Bus services in Prague are provided by a number of transport operators, the chief of which is Dopravní podnik hlavního města Prahy, a.s. (the Prague Capital City Transport Company). Almost all city and suburban buses (as well as the city's metro and tramway lines, the Vltava ferries, and a funicular railway) are run as part of the Pražská integrovaná doprava (PID – Prague Integrated Transport) network, under the management of the regional organizing agency ROPID. History. The first buses in Prague were operated experimentally in 1908 in the Malá Strana district, but the unreliable technology at the  time led to the trial service being declared a failure after 20 months. Regular services did not begin again until 20 June 1925, but have been in continuous operation ever since that date. In the 1990s and 2000s, the metropolitan system was expanded and integrated with suburban transport as Prague Integrated Transport (PID), although a few areas remain outside this system. Buses fulfil many different roles in Prague's public transport system. Many lines serve as connections between the metro, tram, and rail systems and outlying residential areas. There are also plans to gradually introduce trunk services, similar to Latin  America's bus rapid transit systems. Main terminals of metropolitan buses are near metro stations: Černý Most, Zličín, Háje, Letňany, Nové Butovice, Želivského, Českomoravská, Kačerov, Budějovická, Depo Hostivař, Dejvická, Na Knížecí (Anděl), Skalka, Palmovka, Nádraží Holešovice, Florenc etc. Some suburban and long-distance buses stop at these stations. The main stations of long-distance buses are , Černý Most and Zličín. Since 2008, ROPID is implementing a plan to differentiate rachial lines with small intervals and articulated buses. Some telematic systems are widely implemented (GPS monitoring, traffic signal preference). From 2016 the buses in Prague have an average speed of 25,3  km/h. Route numbers. Bus lines belonging to the PID system are numbered within number series: Outside the PID system:
