Book Description
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.

Book Description
This Work Zone Best Practices Guidebook provides an easily accessible compilation of work zone operations practices used and recommended by various States and localities around the country. The Guidebook is a reference document that can be updated with new approaches, technologies, and practices for effectively managing work zones and reducing the impacts of work zones on mobility and safety as they are identified. The best practices are descriptive, not prescriptive. They describe approaches that have been successfully used by transportation agencies, along with contact information to find out more from the agency using the practice. Each organization must determine which of these practices are best suited for its particular situation, considering all the site-specific factors that affect work zone operations.

Book Description
This synthesis documents information regarding the current state of practice for work zone speed management. The report compiles data, procedures, techniques, and technical issues related to observing and comparing work zone speeds. The speed management measures have been organized into four categories: engineering, operational, enforcement, and public education and outreach. Information included in this study was acquired through a review of the literature, two surveys of state department of transportation representatives in all states, a compilation of state agency public information campaigns, and follow-up interviews with select survey respondents from several U.S. states and one Canadian province.

Book Description
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.
