Evaluation of Mobility Impact on Urban Work Zones Using Statistical Models
This work correlated the detailed work zone location and time data from the WisLCS system with the five-min inductive loop detector data. One-sample percentile value test and two-sample … [Read more...] about Evaluation of Mobility Impact on Urban Work Zones Using Statistical Models
Work Zone Traffic Management Analysis Using Analytical Methods
The course provides hands-on training on basic analytical methods (sketch planning methods) to compute work zone performance measures (WZPM). The WZPM includes the following factors: capacity, speed, … [Read more...] about Work Zone Traffic Management Analysis Using Analytical Methods
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
