Speed Behaviour in Work Zone Crossovers. A Driving Simulator Study
Reductions in speed and, more critically, in speed variability between vehicles are considered an important factor to reduce crash risk in work zones. This study was designed to evaluate in a virtual … [Read more...] about Speed Behaviour in Work Zone Crossovers. A Driving Simulator Study
Analysing the Influence of Visible Roadwork Activity on Drivers’ Speed Choice at Work Zones Using a Video-Based Experiment
The present study used a video-based experimental design to investigate the influence of visible roadwork activity on speed preferences at work zones. Four videos from real work zones in Norway were … [Read more...] about Analysing the Influence of Visible Roadwork Activity on Drivers’ Speed Choice at Work Zones Using a Video-Based Experiment
70 mph Study
In July and August 2014, the Pennsylvania Department of Transportation (PennDOT) and Pennsylvania Turnpike Commission (PTC) raised the posted speed limit on rural sections of Interstates 80, 380, and … [Read more...] about 70 mph Study
Vehicle Speeds Variance Analysis in a Freeway Work Zone Based on the K-S Test
To develop effective speed-limit strategies and improve driving safety for work zones, the variance analysis for vehicle speeds in work zones was explored. A method on variance analysis for vehicle … [Read more...] about Vehicle Speeds Variance Analysis in a Freeway Work Zone Based on the K-S Test
Impacts of Construction Work Zone Equipment and Operations on Vehicle Speeds
Mobile construction operations that are conducted at night and do not employ positive barrier systems present significant safety hazards for workers and motorists. As part of several research studies … [Read more...] about Impacts of Construction Work Zone Equipment and Operations on Vehicle Speeds
