Driver Merging and Lane Utilization Behavior Under Zipper Merge Lane Control
Work zone lane closures require drivers to determine when and where to merge from a lane that is about to close to an adjacent open lane. The “zipper merge” strategy encourages drivers to stay in … [Read more...] about Driver Merging and Lane Utilization Behavior Under Zipper Merge Lane Control
Exploration of Color Patterns for Improving Work Zone Safety and Perception
Work zone safety remains a persistent concern in the United States. Color patterns are an effective way to provide visual information for drivers. Existing studies explored the colors of work zone … [Read more...] about Exploration of Color Patterns for Improving Work Zone Safety and Perception
Computer-Aided Multiagent Simulation for Traffic Organization in Highway Construction Zones
