  Following the Islamic Revolution in 1979, the political system changed from constitutional monarchy to Islamic republic. Then the construction of political power in the country needed to change so that new spectrums of political power decision-making centers emerged in Iran. Motives, desires and actions of these new political power decision-making centers in Iran, made them rename streets and public places throughout the country, especially Tehran. For example Shahyad square changed to Azadi square and Pahlavi street changed to Valiasr street. The metropolis of Tehran is equipped with a large network of highways and interchanges.
  
  According to the head of Tehran Municipality's Environment and Sustainable Development Office, Tehran was designed to have a capacity of about 300,000 cars, but more than five million cars are on the roads. The automotive industry has recently developed, but international sanctions influence the production processes periodically. According to local media, Tehran has more than 200,000 taxis plying the roads daily, with several types of taxi available in the city. Airport taxis have a higher cost per kilometer as opposed to regular green and yellow taxis in the city.
