Prague Integrated Transport (Czech: Pražská integrovaná doprava, PID) is an integrated public transport system including metro, tramways, railways, city bus and coach services, Petřín funicular and P+R services. PID operates in Prague and in Praha-východ, Praha-západ, Mělník, Beroun, Příbram, Kladno, Kolín, Kutná Hora, Benešov, Mladá Boleslav and Nymburk areas of Central Bohemia.
Integration means introducing a single fare and tickets together with unified regulations, route numbering plan, some parts of the information system, transfer facilities improving mixed-mode commuting, and also unified service subsidy system. Prague Integrated Transport is co-ordinated by ROPID.
Previously, Prague transport system used to be called IDS (integrovaný dopravní systém – integrated transport system). Modern name (pražská integrovaná doprava) was first used in 1993 as a part of the name of ROPID organisation, which has also started using this name for the transport system itself.
Train services included in PID are currently operated by:
City rail services are de facto monopolised by Dopravní podnik hl. m. Prahy, which operates all Prague tram and metro services, and the Petřín funicular. Until now, there have not been any realistic proposals of any other transporter to operate any services of this kind.
