Analysis of the Field Effectiveness of General Motors Model Year 2013-2020 Advanced Driver Assistance System Features

Abstract

Over 10.9 million Model Year 2013–2020 vehicles were matched to police-reported crashes from 14 states to examine the effectiveness of GM ADAS features. The quasi-induced exposure method was used, with logistic regression used to adjust for 13 covariates. Results indicated fusion/radar Automatic Emergency Braking (AEB), camera AEB, and Forward Collision Alert systems reduced rear-end striking crashes by 45%, 40%, and 20%, respectively. When restricting to crashes with suspected minor or higher injury severities reported, reductions were elevated to 58%, 55%, and 25%, respectively, providing evidence of additional crash mitigation benefits. Similarly, the Lane Keep Assist with Lane Departure Warning system provided 17% and 10% reductions in roadway departure and same direction sideswipe crashes, respectively, with corresponding injury reduction benefits elevating to 21% and 16%, respectively. The Lane Change Alert with Side Blind Zone Alert system reduced lane change crashes by 16%. Reverse Automatic Braking (which includes Rear Cross Traffic Alert, Rear Park Assist, and Rear Vision Camera) produced an 83% reduction in backing crashes. Front Pedestrian Braking reduced front pedestrian crashes by 23%. IntelliBeam (auto high beam headlighting) provided a 22% reduction in a combined set of (unlighted) nighttime animal, pedestrian, and bicyclist crashes. These results provide further evidence of widespread ADAS field benefits, as well as identify opportunities for moving closer toward a zero crashes vision.
