One great way to deal with bumper to bumper traffic is the fast expanding subway system in Tehran and some other megacities.
Tehran Metro company is one of the biggest investors in the public transport development plan. People waste millions of hours of their precious time in traffic jams, and the emissions from the exhaust-pipe of motor-vehicles, put the health of the current and future generations at risk.
With a population of more than 10 million, Iran’s capital city Tehran, is one of the most polluted in the world and famous for its kilometers-long rush-hour traffic jams. If you live in Tehran these days, the best way to go from A to B away from the choking automobile exhaust and blaring horns, is the fast expanding subway system, known locally as the Metro.
Studies have found that light passenger vehicles are to blame for more than 77 percent of the air pollution in Tehran. Motor-bikes come in second with more than 19 percent. Next in line, passenger buses with more than one percent. And lastly, vehicles that consume diesel fuel with 1.72 percent. On average, two people die in auto-collisions and other related accidents and 20 times as many are injured in Tehran every day.
By comparison, the subway as the safest rapid transit system in the city hasn’t experienced any collisions in the 15 years since it became operational. Iran has been able to cut down on gas consumption significantly by expanding the metro system, saving the country an estimated 270 million dollars a year in gas purchases.
The studies done in the Metro are that, in terms of fuel only, an annual $273000, is saved. Also, every metro trip saves every Tehrani passenger 25 minutes. The northern half of line 3 came on stream on September 22, 2015. With 28 stations, it runs 37 kilometers connecting Tehran’s South to its north. It intersects with other lines on its way and is the longest underground electric railway line to have been built in the Middle East to date.
This project accounts for only one of the Tehran Metro’s seven lines. Four of the lines are already in operation, and two others still under construction. The whole system that includes 5 lines at the moment, is 217 kilometers long and carries more than three million passengers a day. Metro authorities are hoping for the number of trips to rise to nine million a day once the construction of all the lines is completed.
