Izmir, on the other hand, has the densest metro system carrying 100 mn passengers on 20-km-long network.
Bursa’s light metro system carried 80 mn passengers on 40-km-long network. Since light metro on ground is much cheaper than underground metro, Bursa’s system shines out with low cost-high capacity.
