Perhaps unbeknownst to you, there’s a lot of tech in your city’s streets and traffic lights that make things run more smoothly. And so despite a growing population and a growing number of cars on the road, gas-guzzling congestion and dirty emissions just might cede, thanks to technology that’s improving traffic flow management.
