Smarter Stoplights Can Reduce Energy Consumption and Emissions of Urban Traffic
Frustration and irritation are standard emotions felt by drivers stuck day to day in city congestion. Heavy traffic, however, increases much more than just the population’s blood pressure: it also emits excessive greenhouse gas emissions to the atmosphere. A recent study led by CEE Professor Carolina Osorio offers efficient methods of programming a city’s stoplights to tackle these challenges. “What we do is develop algorithms that allow major transportation agencies to use high-resolution models of traffic to solve optimization problems,” said Professor Osorio, lead author of the study. The studies developed unprecedented algorithms to retime traffic lights; ultimately improving travel times as well as reducing fuel consumption and emissions across the city. Read the MIT News story.
