Copenhagen has been trying to implement road pricing (like London’s Congestion Charge), but is being blocked by central government. So…
he has now proposed something City Hall calls ‘Intelligent Traffic Control’.
It involves setting up sensors that measure air pollution in Copenhagen and the levels of pollution they report will regulate the traffic heading into the city.
If the pollution levels are too high on any particular day, all the traffic lights on the main roads into the city will turn red and stay red longer than normal. The time the traffic lights are green will be reduced by 10 percent.
