| Abstract | Collision warning systems (CWS) are a relatively new technology to reduce or mitigate motor vehicle rear-end and side impact collisions. This study compared available police-reported crash experiences of 6,143 CWS-equipped heavy trucks with the experiences of 383,058 heavy trucks without CWS. Data were from the Motor Carrier Management Information System (2000-2002). 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, (40% vs. 49%, p<0.0001; 62% vs. 67%, p<0.004 respectively). These changes are the first crash-data based evidence that supports the design effect of CWS. However, more studies are needed to determine the specific impacts of CWS on heavy truck crashes. | | Keywords | Trucking; Truck-drivers; Drivers; Warning-systems; Motor-vehicles; Accidents; Accident-analysis; Accident-statistics | | Contact | Guang X Chen, National Institute for Occupational Safety and Health, 1095 Willowdale Road, Morgantown, WV 26505 | | Publication Date | 20050701 | | Document Type | Journal Article | | Email Address | gchen@cdc.gov | | Fiscal Year | 2004 | | NTIS Accession No. | | | NTIS Price | | | ISBN No. | 0768015512 | | Issue of Publication | 2 | | NIOSH Division | DSR | | Priority Area | Disease and Injury: Traumatic Injuries | | Source Name | SAE 2004 Transactions Journal of Commercial Vehicles | | State | WV |
