The metropolis of Tehran enjoys a huge network of highways  and of interchanges’ ramps & loops. The city has a wide lines of buses and has experienced BRT lines from 2007 in from east side to west. There is a huge amount of Taxis and many Taxi agencies in Tehran. In 2001 a metro system that had been in planning since the 1970s opened the first two of seven envisaged lines. Work has been slow and coverage remains very limited. Development of the Tehran metro system had been interrupted by the Islamic Revolution and the Iran-Iraq War. Problems arising from the late completion of the metro led to buses taking on the role of the metro lines, serving mainly long distance routes. Taxis filled the void for local journeys. The taxis only drive on main avenues, and only within the local area, so it may be necessary to take several taxis to get to one's final destination.


Tehran is served by Mehrabad International Airport, the old airport which is located in the western part of the city, and Imam Khomeini International Airport, 50 kilometres south, which handles international flights. Tehran also has a central train station with connecting services round the clock to various cities in the country. There are four bus terminals that also provide connections at low fares. These are the South, East, West, and Bei-haghi Park-Drive Terminals.
