On the Relationship of Crash Risk and Driver Hours of Service

چکیده
Abstract: Changes in the U.S. hours of service policy in January 2004 argue for an assessment of the safety implications of the new policy. Time-dependent logistic regression and case-control sampling are applied to derive a sample of 231 crashes and 462 non-crashes during 2004 for three national-scale trucking companies. The analysis focuses on changes in crash risk associated with driving up to 11 hours in one duty period and multi-day driving schedules over 7 days. Separate analyses of sleeper and non-sleeper crash risk are conducted as the risk factors associated with these operations were found to be different.
