Flagger Effects in Reducing the Likelihood of Rear-End Collisions for In-Platoon Vehicles in Work Zones
Rear-end collisions are among the most dominant crash types in work zones. Three factors may increase the potential of rear-end collisions in work zones: following too closely, speeding, and faster … [Read more...] about Flagger Effects in Reducing the Likelihood of Rear-End Collisions for In-Platoon Vehicles in Work Zones
Field Evaluation of Automated Flagger Assistance Devices in Work Zones on Two-Lane Roads
Automated flagger assistance devices (AFADs) are designed to be operated remotely by a flagger positioned outside of the travel lanes and thus to reduce the flagger's exposure to vehicular traffic. … [Read more...] about Field Evaluation of Automated Flagger Assistance Devices in Work Zones on Two-Lane Roads
