In India, they set a traffic light that stays red until drivers stop honking

Mumbai police began to fight the constant roar on the road with an experimental traffic light, where the red light timer is updated every time drivers start to loudly signal.

In most countries, a car hornused as a signal in an emergency or as a warning, but in India people often abuse it, using it to express emotions. As a result, densely populated cities suffer from harmful sound pollution.

To solve this problem, the police in Mumbai installed the busiest intersections are digital sound level meters,connecting them to the LED display and traffic light. Each time the noise level reaches 85 dB or higher, the red light timer is updated. At the same time, drivers see the current indicator and the consequences of their actions.

So far, tests have been conducted for 15minutes per day at several intersections, but next month they plan to install similar systems in 10 more places. In the future, the police hopes to introduce such a practice everywhere.

The impetus for this decision was thatMumbai ranks 4th in the world in terms of traffic load, according to the TomTom index. According to the service, last year, on average, drivers spent about 8 days in traffic jams.

Since 2019, France has also begun to combat noise pollution. In the fall, noise radars were installed in Paris, which automatically fine loud vehicles.
