Delhi – the need for a mass rapid transit system As cities grow in size, the number of vehicular trips on road system goes up. This necessitates a pragmatic policy shift to discourage private modes and encourage public transport. Delhi has experienced phenomenal growth in population in the last few decades. Its population has increased from 57 lakhs (5.7M) in 1981 to > 120 lakhs (12 M) presently. For want of an efficient mass transport system, the number of motor vehicles has increased from 5.4 lakhs (540k) in 1981 to 40 lakhs (4M) by now. The number of motor vehicles in Delhi is now more than that of Mumbai, Calcutta, Chennai put together. The result is extreme congestion on Delhi roads, ever slowing speeds, increase in road accidents fuel wastage and environmental pollution with motorized vehicles alone contributing to about two thirds of the atmospheric pollution.
