There could soon be a cap on the registration of new cars in cities grappling with congestion and pollution. This is one of the moves being mulled over by the Centre in consultation with state governments, reported The Times of India. According to the Centre's new roadmap, there could also be congestion taxes and disincentives on purchasing a second car.

“The roadmap is to ensure there is ease of transport and enhancing customer experience in transaction with transport and police departments.One of the proposals is to have a common portal for tax payments such as entry tax, state permit fee and other such charges. Since improving public transport is the key to check growth of private vehicles, there is a proposal to liberalise the sector to allow more private players to run buses,“ a government official told the English daily.

As of March 2015, there are 27.9 lakh cars in Delhi out of a total 88.27 lakh vehicles. In Mumbai, it's 8.5 lakh cars of 27 lakh vehicles, while Bengaluru has around 10 lakh cars out of 58 lakh vehicles.
