Anyone who circulates in large cities is well aware of the torment of car horns and the stress of traffic lights. Drivers have little patience and take revenge on their horns to complain about everything and nothing.
What if the lights on the traffic lights turned red? The strategy is interesting and seems to work.
If the number of decibels exceeds 85 dB… traffic lights are red
To combat noise pollution, the Mumbai Police in India implemented an “anti-horn” system. This system, implemented at traffic lights, is based on a set of noise detection sensors that operate whenever the number of decibels exceeds 85 decibels.
The more drivers use the horn, the longer they have to stand in traffic queues, The New York Times. The noise sensors were installed in strategic areas.
In addition to the increased waiting time, the Mumbai Police also have warning phrases to raise awareness among drivers.
The Mumbai Police posted a short video on Twitter showing the system in action.

The exercise was carried out at the end of last year, and law enforcement agencies have been discussing how to implement it across the city where more than 20 million people live.
