Speed Reduction Methods and Studies in Work Zones: A Summary of FindingsAuthor/Presenter: Benekohal, Rahim F.
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 a 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.
