Shiraz has one of the most efficient public transportation system in Iran. Most of the people living in the city use public transportation on a daily basis. The city subway system with 6 lines is the second largest subway system in Iran. However, by 2018 only the first line is operational and active which extends from south-east to north-west of the city. Taking a taxi in Shiraz is very easy, and there are taxi terminals in different corners of the city. They provide 24-hour service to the passengers.
