Stimulation of public transport in urban areas

We might not be able to make the cars expensive because the car companies always compete with one another, and therefore the prices will actually go down. And moreover if cars are expensive it is the people who are rich who will be benifit with that. And if parking charges are increased it is the owners of the parking lots who will stand to gain. So without change in the production of cars, if the driving space (or separate lane for private vehicles is made)for cars on the road is reduced and more space allotted for public transport...then the cars may be used sparingly. There is no case of pollution if the capacity of the car is to its full.

I think what is most important is to make the public transport network good and cheap. I live in London and the public transport network is good, though it is expensive - but driving takes longer and parking is a pain. So people prefer taking the public transport. I am originally from Delhi and I would love to use the public transport in Delhi but buses tend to be too crowded and the Metro doesn't cover much of the city. Hope it gets better soon and the frequency increases to reduce the rush on the trains.
