Abstract:

The main objective of this work is to provide a better understanding of the fuel consumption and environmental costs of vehicle operations at signalized intersection approaches. The analysis was done using advanced engine modeling software. Four different driving modes were compared: idling, cruising at different operating speeds, speed, accelerating from a stopped condition to a target operating speed, and accelerating from a non-zero speed to a target operating speed. The results of this analysis show that fuel consumption and the environmental costs of stops and delays at signalized intersection approaches are highly correlated to the corridor operating speed. Another factor that significantly impacts the fuel consumption and environmental costs at signalized intersection approaches is the drivers’ acceleration patterns. Aggressive driving with high acceleration rates yields significantly higher fuel consumption and emission rates because of the high fuel/air ratio needed for this type of aggressive accelerations. Intersection and corridor control plans that are aimed to minimizing stops at approaches with high operating speed and driver educating campaigns to reduce aggressive accelerations can lead to a significant reduction in the fuel consumption and environmental costs of vehicle operations at signalized intersection approaches.
