‘Better traffic signals can cut greenhouse gas emissions’

MIT News

April 2015

A study by researchers at the Massachusetts Institute of Technology could lead to better ways of programming traffic lights to reduce delays, improve efficiency, and reduce emissions.

While existing programs can simulate both city-scale and driver-scale traffic behaviour, integrating the two has been a problem. Using Aimsun traffic studies in the Swiss city of Lausanne, Assistant Professor of Civil and Environmental Engineering Carolina Osorio and alumna Kanchana Nanduri developed new algorithms that reduced the amount of detail enough to make the computations practical, while retaining enough specifics to make useful predictions and recommendations.
