The opening of Delhi Metro Rail Corporation's third line on December 30 will mark the end of Phase I of the Metro Rail project in the national Capital, and it will have done much more than just provide fast, efficient, comfortable and clean means of transport. The Delhi Metro network carrying about six lakh passengers everyday would be there for everyone to see, but what would probably go unnoticed was that it would have siphoned off the roads 2.2 million commuter trips per day. This would mean more than 2650 less buses on the city streets and 5.17 lakh per year less trips by private vehicles. This would help in reducing road accidents by about 30 per cent
