In large cities like Delhi and Kolkata, traffic congestion accompanying the increase in road traffic demands has become a serious issue, accelerating economic loss and health hazards caused by atmospheric contamination, noise and other forms of vehicle-related pollution. Consequently, there is a need to develop a public transportation system for alleviating traffic congestion and improving the urban environment. The objective of this project is to cope with the surge in traffic demand in the Delhi metropolitan area, the capital city of India, by extending the mass rapid transportation system with a total length of approximately 83 km, and thereby promoting regional economic development and improving urban environment, through mitigation of traffic jams and decrease of pollution caused by the increasing number of motor vehicles.
