DNA has this article on how different yardsticks apply for road projects in Mumbai and Delhi.
'On Thursday the ministry had put a caveat that if Mumbai wants to upgrade roads, even if under the Jawaharlal Nehru National Urban Renewal Mission, it would have to make space for cyclists and pedestrians.
But in Delhi the ministry sees no cause for concern in the city government's plans to build 25 new flyovers and road over-bridges, without any dedicated space for pedestrians and cyclists, at an estimated cost of Rs 1,650 crores in next four years,' the article says.

The roads in Delhi are certainly better than the ones Mumbai. But there is still a lot of work happening in Mumbai, and roads are getting better.
We think having dedicated corridors for pedestrians and cyclists is a good idea. If you ignore them, then they will spill on to the roads and it will lead to chaos and accidents.
