Automatic Emergency Braking (AEB) systems can improve safety by activating the vehicle’s braking system in detection of a potential collision. This study developed a methodology to estimate and quantify potential reduction in energy consumption and tailpipe emissions due to the AEB system as a result of effectiveness in collision avoidance. The main idea of this methodology was to identify traffic accidents that can be potentially avoided by AEB systems, and predict the environmental impact of AEB systems under a “what-if” scenario (i.e., no accident). Real-world scenarios for Riverside, CA and Las Vegas, NV were studied using the proposed methodology as case studies to demonstrate the efficacy of the proposed methodology.
