Tehran International Airport

The Tehran International Airport is designed to cope with the following factors: Ability to handle a large volume of traffic at its inception in the early 1980's and increasing steadily throughout the years; a site located 31 miles (50 km) from downtown Tehran; an arid desert-like climate. The airfield consists of dual-parallel runways with one pair built initially on either side of the terminal area. This area is traversed by a spine roadway system which joins the passenger terminal with all support facilities. The airport is designed to be linked to Tehran with a high-speed train. This train will be able to travel at a top speed of 80 mph (129 km/hr) in open stretches, and, as well, make stops at each of the terminal modules spaced some 1,500 ft (457.5 m) apart. The terminal itself will be doubled-loaded with train tracks and roadways in the middle. Aircraft gate positions will be arranged in clusters or groups of seven international or eight domestic gates per module - again with pairs of modules on either side of the rail and roadway access.
