TY - CONF AB - <p>There are several safety issues in work zone areas due to decrease lane width, and presence of large equipment and on-site workers. The safety issues are compounded for drivers that are also drug impaired. In this study, we examine the driver performance of 18 commercial bus operators in a simulated environment while they are under the influence of a benzodiazepine drug (Triazolam). The findings show that those drivers under the influence of the drug had higher steering entropy and greater difficulty staying close to the intended travel lane when compared to those who were not under the influence of the drug. These wider travelling distances around work barrels, by those under the influence of Triazolam, could have a potential impact on the safety of nearby construction workers and heavy machine operators.</p> AU - Chris Deits, Linda Ng Boyle, John Morrison DA - 2011/6// DO - 10.17077/drivingassessment.1432 IS - 2011 VL - 6 PB - University of Iowa PY - 2011 TI - Driving Performance of Drug-Impaired Bus Drivers in Work Zone Areas T2 - Driving Assessment Conference UR - https://pubs.lib.uiowa.edu/driving/article/id/28678/ ER -
