The draft parking rules for Delhi, which were opened for feedback, stress on the need to decongest Delhi roads by giving incentives for parking in multi-level parking lots. Close to 1,400 cars are added to Delhi roads each day, while there are only close to 250 surface parking lots in the city and only a handful of multi-level lots.

There have been several traffic management measures taken in Delhi, the odd-eve traffic experiment conducted in year 2016 was first of its kind. CPCB took it as an opportunity to explore if there was any significant reduction in ambient noise levels due to restrictions in number plates.

The current overview report is part of the output report for the project “Supporting Smart Urban Mobility and Built Environment in Indian Cities” under Grant Ref: G 15 SSEF-140 , implemented during period of October 2015 to January 2017.
