But the Atlas of Urban Expansion, a project based in New York University, estimates that roads built in Ahmedabad after 2000 are 8.5m wide, on average, compared with 7.2m for roads built earlier. Roads also take up more of the land area in the newly developed suburbs. Because wide roads can carry more cars and buses, future suburbanites in Ahmedabad ought to be spared the awful traffic jams that frustrate large Indian cities such as Delhi and Mumbai.
I grew up next to a three lane street(roughly 18m in total width) that lead to the suburbs which in turn experienced rapid growth during the nineties, continuing a few years into the 21st century.
The additional few tens of thousands of new inhabitants commuting each day to work were enough to turn this place into congestion hell.
I don't think 8.5m - even each way is going to cut it in a city of well over 5 million.
