Cycle rickshaws and auto rickshaws are the main mode of transport, with close to 400,000 rickshaws running each day – the largest number for any city in the world. However, only about 85,000 rickshaws are licensed by the city government. Relatively low-cost and non-polluting cycle rickshaws nevertheless cause traffic congestion and have been banned from many parts of the city. Public buses are operated by the state-run Bangladesh Road Transport Corporation (BRTC) and by private companies and operators. Scooters, taxis and privately owned automobiles are increasingly becoming popular with the city's growing middle class. The government has overseen the replacement of two-stroke engine taxis with "Green taxis" locally called CNG, which run on compressed natural gas.
