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.
