Public transport

Bucharest's public transport system is the largest in Romania and one of the largest in Europe. It is made up of the Bucharest Metro, run by Metrorex, as well as a surface transport system run by STB (Societatea de Transport București, previously known as the RATB), which consists of buses, trams, trolleybuses, and light rail. In addition, a private minibus system operates there. As of 2007, a limit of 10,000 taxicab licences was imposed.
