A Comparison of Crash Patterns in Heavy Trucks With and Without Collision Warning System Technology

This study investigates the highway crash experience of heavy trucks equipped with collision warning systems (CWS) by comparing available police-reported crash experiences of 6,143 CWS-equipped heavy trucks with the experiences of 383,058 heavy trucks without CWS. Data from the Motor Carrier Management Information System for 2000-2002 was used. Results suggest that CWS-equipped trucks had a significantly lower proportion of crashes involving other moving vehicles and a significantly lower proportion of multiple vehicle crashes compared to trucks without CWS. These results are the first real-world crash data evidence to support the design effect of CWS. Limitations of this study are discussed.
