Traffic Emission Reduction at Signalized Intersections: A Simulation Study of Benefits of Advanced Driver Information

Emissions from motor vehicles are the primary cause of deterioration of urban air quality. Altering driver behavior can potentially contribute to the reduction of emissions and pollutants. Previous studies revealed that unnecessary acceleration and hard braking in response to sudden changes of traffic signals causes significant wasted energy. Providing drivers with advance information about traffic signal status can potentially result in modifications of driving behavior so that drivers will exhibit smoother driving profiles. These smoother profiles provide benefits particularly by reducing hard braking in front of intersections when the green signal phase ends. This paper, through both analysis and simulation, investigates the potential benefits on emissions and energy consumption of making traffic signal status information available to drivers. Safety benefits of this approach are also discussed.
