Vision Zero is an approach to transportation safety that aims to eliminate all traffic-related fatalities and lifelong injuries. A common strategy to achieving Vision Zero is the safe system approach, which employs a multitude of transportation-related branches to create a safe system for all road users. The design and implementation of advanced driver assist systems (ADAS) is one way to contribute to Vision Zero. This study used real-world nationally representative crash data from the Crash Investigation Sampling System to estimate the contributions of two ADAS to achieving Vision Zero in the United States: an advanced automatic emergency braking system (AAEB) and lane support systems (LSS). It was assumed A-AEB has crash avoidance capabilities for rear-end crashes, left turn across path opposite direction and lateral direction crashes, and straight crossing path crashes, as well as injury mitigation capabilities due to prevented crashes as well as due to delta-v reduction due to system-induced braking. It was assumed LSS has crash avoidance capabilities for head-on crashes, road departure crashes, and opposite direction sideswipe crashes. The combined contributions were estimated to prevent a cumulative 7,054,894 crashes and 869,456 moderate to fatal injuries by 2050. Despite this, over 125,000 moderate to fatal injuries are still estimated to occur each year, and the total number of crashes is not expected to decline. This emphasizes the need for continuous future contributions from all branches of transportation if the US is to someday achieve Vision Zero.
