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. Volume II of the final report, contains a detailed report of the study, including all of the information that is included in Volume I, which contains the summary of findings, conclusions, and recommendations.

The objectives of this project were to determine the effectiveness of speed control methods and study traffic behavior in construction zones. This report provides a brief introduction and summary of findings from the following reports which were prepared as part of this study: (1) Evaluation and Summary of Studies in Speed Control Methods in Work Zones. (2) Evaluation of a Radar-Activated Horn System for Speed Control in Highway Maintenance Operations. (3) Survey of Driver's Opinion about Work Zone Traffic Control on a Rural Highway. (4) Speed Reduction Effects of Drone Radar in Rural Interstate Work Zones. (5) Speed Reduction Effects of Changeable Message Signs in a Construction Zone. (6) Effects of Police Presence on Speed in a Highway Work Zone: Circulating Marked Police Car Experiment. (7) Evaluation of Work Zone Speed Limit Signs with Strobe Lights. (8) Speed Reduction Profiles of Vehicles in a Highway Construction zone. Data only for those vehicles in free flow traffic are used for speed reduction evaluation. A vehicle was considered to be in free flow traffic when its time headway was greater than 5 seconds.

Studies have shown that drivers are at a higher risk of being involved in a crash when travelling through a work zone compared to normal driving conditions. Research further suggests that the crashes that occur in work zones are, on average, more severe than crashes that occur outside of work zones. The periods while temporary traffic control is being set-up, removed, or modified are also especially concerning given the exposure of the workers to traffic and the transition in the driving environment. This study aims to investigate the safety hazards and risk present during set-up, removal, and modification of temporary traffic control on high-speed roadways, and identify potential practices for improving safety during the traffic control deployment and removal processes. To date, the researchers have performed a comprehensive literature review on the study topic and conducted a survey of state department of transportation and highway construction contractor personnel. The results reveal a lack of a standard process/procedure and detailed guidance for setting up and removing traffic control. The survey results expose steps in the process that pose high risk to workers and motorists, such as when the traffic control is being placed to initially set the taper to close a lane. This document is an interim report that describes the study results to date and provides a proposed methodology for the remaining study tasks.

Highway work zones create potential hazards because motorists are confronted with unexpected and often confusing situations. The objective of this research study was to examine motorists' perceptions, opinions, expectations and other psychological factors, which influence their driving activity in highway work zones. The study was carried out in two parts: an opinion survey and focus groups. A two-page questionnaire was distributed to 2,246 automobile and truck drivers.
