Analysis of Truck Drivers’ Opinions on Safety and Traffic Control on Highway Work Zones Volume I. Summary of Findings

This study was conducted to determine the truck drivers’ travel characteristics, concerns about work zone traffic control devices, and assessment of work zone features, as well as to determine the location of accidents and bad driving situations based on the experiences and perceptions of truck drivers. A statewide survey of semi-truck drivers was conducted in 6 locations in Illinois. The questionnaire contained 43 questions about truck drivers and travel characteristics, drivers’ assessment of work zone features and traffic control devices, their accident and bad driving situation experiences, and their suggestions for improving traffic flow and safety in the work zones. About 930 truck drivers participated in the survey, and the responses from 834 of them were found suitable for further data analysis. The frequency of the responses to each question were analyzed. Also correlation analyses were conducted to identify the relationships among the surveyed questions. Different statistical tests were used for data analysis. This volume and Volume II contains the findings of the study.
