MASH Allowable Flare Rates for Portable Single-Slope Concrete Barriers
Portable concrete barriers (PCBs) are commonly used to provide positive protection in work zones. They also shield work-zone personnel from errant motorists when activities are being performed near … [Read more...] about MASH Allowable Flare Rates for Portable Single-Slope Concrete Barriers
SafeSpeed: Enhancing Work Zone Safety Through Speed Enforcement / Impact of Work Zones on Crash Occurrence: A Texas Case Study
Work zones are essential for maintaining and improving road infrastructure. However, their presence can alter traffic conditions and increase the risk of crashes. This research project applies a … [Read more...] about SafeSpeed: Enhancing Work Zone Safety Through Speed Enforcement / Impact of Work Zones on Crash Occurrence: A Texas Case Study
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
Incident Management in Interstate Work Zones
Incidents in interstate work zones can create challenges for incident management, especially when temporary traffic barriers and limited shoulder pull-off areas are present. This project identified … [Read more...] about Incident Management in Interstate Work Zones
Night Versus Day Work—Balancing Safety, Operations, and Constructability for Short-Term Operations on Two-Lane Roads
Allowable work hours (AWH), also known as Allowable Closure Hours or Limitations on Operations, for a contract dictate which hours of the day construction and maintenance activities may occur and are … [Read more...] about Night Versus Day Work—Balancing Safety, Operations, and Constructability for Short-Term Operations on Two-Lane Roads
