SPEED REDUCTION METHODS AND STUDIES IN WORK ZONES: A SUMMARY OF FINDINGS. FINAL REPORT

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; and (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.
