Biggest increase in ridership
Antalya is on the top of list of increase in ridership compared to 2016, far ahead of the other cities. As Expo/Airport line is commissioned, the number of passengers were more than doubled.
The second city on the list is Ankara, increasing the ridership by 7%.
Istanbul was the only city where ridership decreased in 2017. Eurasia tunnel (the new tunnel for cars) might be the cause of this decrease.
Neither Gaziantep and Adana are taken into account since the 2017 figures are not available, nor Kocaeli, since tram system was commissioned in 2017.
