Transit in Iran
Iran has a long paved road system linking most of its towns and all of its cities. In 2007 the country had 178,152 km (111,000 mi) of roads, of which 66 percent were paved. There were 55 passenger cars for every 1,000 inhabitants. Trains operated on 11,106 km (6,942 mi) of railroad track. The country’s major port of entry is Bandar-Abbas on the Strait of Hormuz. After arriving in Iran, imported goods are distributed throughout the country by trucks and freight trains. The Tehran-Bandar-Abbas railroad, opened in 1995, connects Bandar-Abbas to the railroad system of Central Asia via Tehran and Mashhad. Other major ports include Bandar e-Anzali and Bandar e-Torkeman on the Caspian Sea and Korramshahr and Bandar e-Khomeyni on the Persian Gulf. Dozens of cities have airports that serve passenger and cargo planes. Iran Air, the national airline, was founded in 1962 and operates domestic and international flights. All large cities have mass transit systems using buses, and several private companies provide bus service between cities. Tehran, Mashhad, Shiraz, Tabriz, Ahvaz and Esfahan are in the process of constructing underground mass transit rail lines.
International North-South Transport Corridor (INSTC) is a multi modal transportation established in 12 SEP 2000 in St. Petersburg, by Iran, Russia and India for the purpose of promoting transportation cooperation among the Member States. This corridor connects India Ocean and Persian Gulf to the Caspian Sea via Islamic republic of IRAN, and then is connected to St. Petersburg and North European via Russia Federation. Due to this fact that northern neighbors of IRAN do not have access to open water and the cost of transportation is so high by other means, IRAN has got an exceptional privilege by its strategic geographic location.
The INSTC was expanded to include eleven new members, namely: Republic of Azerbaijan, Republic of Armenia, Republic of Kazakhstan, Kyrgyz Republic, Republic of Tajikistan, Republic of Turkey, Republic of Ukraine, Republic of Belarus, Oman, Syria, Bulgaria.
