Analysis of the Field Effectiveness of General Motors Model Year 2017-2021 Advanced Driver Assistance System Features

Abstract

Over 11.2 million Model Year 2017–2021 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 49%, 40%, and 14%, respectively. When restricting to crashes with suspected minor or higher injury severities reported, reductions were elevated to 57%, 53%, and 25%, respectively, providing evidence of additional crash mitigation benefits. Similarly, the Lane Keep Assist with Lane Departure Warning system provided 17%, 8%, and 7% reductions in roadway departure, same direction sideswipe, and opposite direction sideswipe crashes, as well as a 22% reduction in injuries reported for roadway departure crashes. The Lane Change Alert with Side Blind Zone Alert system reduced lane change crashes by 15%. The backing crash findings indicated Rear Vision Camera, Rear Park Assist, Rear Cross Traffic Alert, and Reverse Automatic Braking (note more advanced backing features generally include all less advanced backing features) provided 34%, 49%, 62%, and 85% reductions in backing crashes, respectively. Front Pedestrian Braking reduced front pedestrian crashes by 23%. These results provide further evidence of widespread ADAS field benefits, as well as identify opportunities for moving closer toward a zero crashes vision.
