Field Study of Heavy-Vehicle Crash Avoidance Systems
In 2013 there were 3,964 people killed and an estimated 95,000 people injured in crashes involving large trucks. In order to reduce crashes many trucks are currently equipped with crash avoidance systems (CASs), which alert drivers to impending conflicts with objects and initiate automatic emergency braking (AEB). A total of 169 drivers operating 150 CAS-equipped trucks from seven trucking companies across the country participated in a 1-year field operational test, which included video and vehicle data to study CASs in a naturalistic environment. In over 3 million miles of data, no rear-end crashes of the type CASs are designed to prevent were identified. A total of 6,000 CAS activations were sampled and analyzed to evaluate their reliability. A high-priority activation was most likely to occur when the driver needed to take action. Lower priority activations were generally advisory and did not require immediate driver response. Fleet safety managers reported that they would recommend CAS technology. While the CAS user experience can be improved, and some activation types were found to be less reliable than others, the results from this study suggest that the overall systems work as intended
