Predicting safety benefits of a collision warning system and adaptive cruise control in commercial trucks

DOT funded a partnership led by Volvo Trucks North America, Inc. (VTNA) to test the VORAD collision warning system (CWS) and adaptive cruise control (ACC) and an advanced braking system (AdvBS) in commercial truck operation through a field operational t. This paper demonstrates an approach for evaluating the efficacy of CWS, ACC, and AdvBS for preventing rear-end crashes. Safety benefits are estimated using a model that combines historical crash rates with statistical estimates of the incidence and severity of near-crash events. These events are detected and characterized using vehicle dynamics models and data from onboard data recorders. Safety benefits are measured as the percentage of rear-end crashes that could be avoided by CWS and ACC usage.
