Evaluating Driver Response to a Speed Feedback Trailer at Median Crossovers Within Freeway Construction Work Zones
A series of field evaluations were performed to assess the speed reduction effects of a speed feedback trailer (SFT) positioned at various locations before and after a median crossover section within … [Read more...] about Evaluating Driver Response to a Speed Feedback Trailer at Median Crossovers Within Freeway Construction Work Zones
Real-Time Conflict Prediction for Large Truck Merging in Mixed Traffic at Work Zone Lane Closures
Large trucks substantially contribute to work zone-related crashes, primarily due to their large size and blind spots. When approaching a work zone, large trucks often need to merge into an adjacent … [Read more...] about Real-Time Conflict Prediction for Large Truck Merging in Mixed Traffic at Work Zone Lane Closures

Safety and Mobility Impacts of Work Zone Lane and Shoulder Widths
The goal of this research was to quantify the mobility and safety impacts of different combinations of lane width and shy distance to the barrier for a given paved width in work zones. The research … [Read more...] about Safety and Mobility Impacts of Work Zone Lane and Shoulder Widths
Passive Sensing Communication to Vehicles in Construction Work Zones Through Signage Coded on Pavement Surface
Construction work zones (CWZ) present safety challenges because of speeding, distracted driving, and improper lane changes. The objective of this research was to enhance CWZ communication and safety … [Read more...] about Passive Sensing Communication to Vehicles in Construction Work Zones Through Signage Coded on Pavement Surface
