Bus Rapid Transit can be defined as a flexible, rubber-tired form of public transport that combines stations, vehicles, services, running ways and information technologies, into an integrated system with strong identity, to offer fast, comfortable and low cost urban mobility. Currently, there are about 120 cities with BRT systems or corridors around the world, comprising about 280 corridors serving about 28 million passengers per day. As of January 2011, about 49 new cities were building systems, 16 cities were expanding their corridors, and 31 cities indicated they were considering BRT.
