The findings of this study will help to dientify the high risk location for truck drivers in work zones. A study was conducted to determien the truck drivers' concerns and the location of accidnets and safety problem areas in work zones. A statewide survey of 930 semi-truck drivers was conducted. Two thirds of the drivers had experienced the bad driving situations (BDS) at least at one location, and one third at more than one location in work zones. The transition area had the highest percentage of BDS, followed by the advance warning area, work space, termination area, and buffer space. The correlations between having BDS experiences and travel characteristics were examined for the work zone as a whoel, as well as fro the five sectiosn within the work zone. BDS and accident experiences are highly correlated, so the frequency of BDS can be used as an indicator of safety problem areas in work zones. Analyzing BDS experiences for each section separately revealed correlations between BDS and travel characteristics that were not detected by the overall analysis.
