On the suburban lines, 92 thousand 300 passengers are carried on the Anatolian side, 64 thousand 500 on the European side, and 156 thousand 800 passengers are carried daily. As a result of the meetings it organized, the commission decided to establish 150 new lines on the suburban line route, 2 on the Anatolian side and 2 on the European side, to transport 4 passengers. Bus reinforcements will be made in the existing 6 lines, which carry passengers on the suburban route. For the transportation of passengers using the IETT suburban line, 123 new buses, 90 of which are on the Anatolian side and 213 on the European side, will be taken into the system.
