Traffic is one of the major contributors to noise pollution in Mumbai, the noisiest city in the world
The Government of Maharashtra has installed noise barriers at some locations in Mumbai. The new Development Control Rules make noise barriers mandatory on new flyovers.
A combination of policy change, awareness and enforcement of anti honking is required. Enforcement of Rules for maximum permissible decibel levels of horns and change in driving schools is also required along with policy measures such as noise barriers and noise mapping.
