Success of Delhi Metro Phase One

http://indiatoday.digital... "But the only way to discourage the use of private vehicles is to provide alternatives—ones that are safe, reliable, fast and easily accessible. That is where a rail-based transit system taps into a metropolis' needs, becoming the lifeline of its economic activities. [...] The reasons for this are simple. The economic rate of return and benefits to society from a metro system are evident within five years of its inception. Phase one of the Delhi Metro has taken 39,600 vehicles off the roads, slashed the consumption of petrol, diesel and CNG by 57,800 tonne and saved Rs 288 crore on road maintenance and traffic management."
