Transport in Dubai is managed by the Roads and Transport Authority, a government agency that was formed in 2005. The RTA manages the metro system, buses, trams and taxis. Dubai’s Public Bus Transport system comprises 140 routes, with more than 2,500 buses in service across the city. Many bus shelters are air conditioned, as a measure to encourage people to use public transport.
Private taxi services in Dubai are licensed by the RTA, and are identifiable by their cream bodywork and the colour of the roof. Metro Taxis have orange roofs, Network Taxis have yellow roofs, Cars Taxis have blue roofs, Arabia Taxis have green roofs and City Taxis have purple roofs. The RTA-owned Dubai Taxi Corporation is the largest taxi operator in Dubai and has taxis with red roofs, as well as a fleet called the Ladies Taxi service, which have pink roofs and cater exclusively for female passengers.
