Traffic energy and emission reductions at signalized intersections: a study of the benefits of advanced driver information

Emissions from motor vehicles are a major cause of deteriorating urban air quality. Previous studies revealed that unnecessary acceleration and hard braking in response to sudden changes of traffic signals causes a significant amount of wasted energy and elevated emissions. Altering driver behaviors can potentially contribute to the reductions of vehicle energy/emissions. This paper proposes an advanced driving alert system that provides traffic signal status information to help drivers avoid hard braking at intersections. It also defines a method for evaluating vehicle energy consumption and emissions at intersections, and investigates the potential benefits of such system.
