Field Evaluation of Work-Zone Automated Speed Enforcement Equipment and Traffic Monitoring Devices
Speeding is a significant contributor to a significant portion of highway collisions. For work zones in particular, the speeding problem is compounded by on-site road re-configuration, narrowed lanes, … [Read more...] about Field Evaluation of Work-Zone Automated Speed Enforcement Equipment and Traffic Monitoring Devices
Evaluation of a Motorist Awareness System
The objective of this study was to determine the effects of a Motorist Awareness System (MAS) on vehicle speeds in highway work zones. Spot speed studies were conducted prior to, within, and near the … [Read more...] about Evaluation of a Motorist Awareness System
Modeling Speed Behavior of Passenger Cars and Trucks in Freeway Construction Work Zones: Implications on Work Zone Design and Traffic Control Decision Processes
Current work zone design and traffic control guidance is based on desirable speed outcomes; knowledge related to actual speed outcomes of design and traffic control decisions is limited. The objective … [Read more...] about Modeling Speed Behavior of Passenger Cars and Trucks in Freeway Construction Work Zones: Implications on Work Zone Design and Traffic Control Decision Processes
Real-Time Information Reduces Accidents and Congestion in Work Zones
