Tehran, Traffic & Transportation
Tehran is one of the 10 largest cities in the world. The Traffic Authorities have always been involved by implementing world experiences directly or indirectly as Traffic Solution, based on both of the strategies. Because of complication of problems (due to the concentration of over 10 millions residents in a city without a larg effective public transportation network) automobile (or simply) “Auto” has easily found its place at the first stage in the City Traffic and Transportation Network.
Today “Auto” plays two important roles for transportation in Tehran. Many efforts are done to improve transportation situation and realted isuues such as: air pollution, congestion, safety problem for pedestrians and cyclists, etc.
Any movement in Tehran should be planed base on Traffic zones. There are 2 different type of traffic zones in the city
1- Restricted zone based on car’s registeration number (for Odd & Even days)
2- Central restricted zone which is open for public cars (Buses, Taxis, Ambulances, . . etc)
The metropolis of Tehran enjoys a huge network of highways (280 km) and of interchanges’ ramps & loops (180km). In 2007 there were 130 kilometers of highways and 120 kilometers of ramps and loops under construction. 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. This has all led to extreme congestion and air pollution within the city.
Tehran is served by Mehrabad International Airport, the old airport which doubles as a military base located in the western part of the city, and Imam Khomeini International Airport, 50 kilometres (31 miles) south, which handles flights from the Persian Gulf but which will eventually handle all international flights. The new airport is more than overdue, but is efficient, although security concerns have made the governments of Britain and Australia warn their foreign nationals in Iran.
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.
While the center of the city houses the government ministries and headquarters, the commercial centers are more located toward Valiasr Street, Taleghani Ave, and Beheshti Ave further north. Although administratively separate, Rey, Shemiran, and Karaj are often considered part of the larger Tehran metropolitan area.
