Effect of Work Zone Lighting on Drivers’ Visual Performance and Perceptions of Glare
Nighttime crashes at work zones are major concerns for construction workers and motorists. Although in a majority of the U.S. states, department of transportation specifications for work zone lighting … [Read more...] about Effect of Work Zone Lighting on Drivers’ Visual Performance and Perceptions of Glare
Work Zone Simulator Analysis: Driver Performance and Acceptance of Missouri Alternate Lane Shift Configurations
The objective of this project is to evaluate MoDOT’s alternate lane shift sign configuration for work zones. The single sign proposed by MoDOT provides the traveler with enough information to let them … [Read more...] about Work Zone Simulator Analysis: Driver Performance and Acceptance of Missouri Alternate Lane Shift Configurations
Work Zone Simulator Analysis: Driver Performance and Acceptance of Alternate Merge Sign Configurations
Improving work zone road safety is an issue of great interest due to the high number of crashes observed in work zones. Departments of Transportation (DOTs) use a variety of methods to inform drivers … [Read more...] about Work Zone Simulator Analysis: Driver Performance and Acceptance of Alternate Merge Sign Configurations
Effects of Work Zone Configurations and Traffic Density on Performance Variables and Subjective Workload
This paper investigates the effect of changing work zone configurations and traffic density on performance variables and subjective workload. Data regarding travel time, average speed, maximum percent … [Read more...] about Effects of Work Zone Configurations and Traffic Density on Performance Variables and Subjective Workload
Motorists’ Understanding of Automated Flagger Assistance Devices in Work Zones
Automated flagger assistance devices (AFADs) are designed to be operated remotely by a flagger positioned outside the travel lanes and thus to reduce their exposure to vehicular traffic. There are two … [Read more...] about Motorists’ Understanding of Automated Flagger Assistance Devices in Work Zones
