You have failed to consider the time saved by Metros and Jam free pass ways!! Whereas in Delhi, you are not sure on road to reach office in 1Hr or 2 Hr(in case of Jam), in Metro longest distance takes 40-45 mins & u can be very sure of tht everytime. Additionally, Metro gets cheaper and efficient as load increases whereas BRTS service will degrade as load increases. Hats off to Delhi metro !!
