A pigovian tax is a tax on any market activity that generates negative externalities. One such negative externality is the noise pollution that happens in Mumbai as drivers continually slam on their horns hoping to help speed up the wait at traffic lights. The Mumbia police have issued such a pigouvian tax on the honkers by setting up noise detectors that automatically reset the red light waiting time if the honking gets too loud.
From the article:
For the Mumbai’s perpetual honkers, who love to blare the horns of their vehicles even when the traffic signal is red, the Mumbai Traffic Police has quietly come up with an unique initiative to discipline them in order to curb the alarming rise in the noise pollution levels in the country’s commercial capital.
From Friday (January 31, 2020), it has installed decibel meters at certain select but heavy traffic signals to deter the habitual honkers through a campaign named ‘The Punishing Signal’.
Joint Police Commissioner (Traffic) Madhukar Pandey said that the decibel monitors are connected to traffic signals around the island city, and when the cacophony exceeds the dangerous 85-decibel mark due to needless honking, the signal timer resets, entailing a double waiting time for all vehicles.
Three cheers for the Mumbai police. They have instituted a devilishly clever solution to the city’s insane noise pollution. You’ll enjoy the clip … https://t.co/MI8Oa5B2Sj
