Use of Additional Lighting for Traffic Control and Speed Reduction in Work Zones
Performing roadway construction work at night exposes workers to hazards that are not present or as great during the daytime. Working at night requires illuminating the area where work is taking place … [Read more...] about Use of Additional Lighting for Traffic Control and Speed Reduction in Work Zones
Characterizing the Impact of Nighttime Construction on Traffic-Related Emissions
Nighttime road maintenance and construction work is most commonly initiated where it is impractical or highly undesired to close traffic lanes on certain high-volume roadways during normal daylight … [Read more...] about Characterizing the Impact of Nighttime Construction on Traffic-Related Emissions
Impact of Temporary Portable Work Zone and Personal Lighting on Vehicle Speeds in Nighttime Highway Preservation Projects
Every year thousands of people are killed or injured in work zone crashes in the US due to excessive speed, distraction, inattentiveness, or low visibility. Many highway construction, maintenance, and … [Read more...] about Impact of Temporary Portable Work Zone and Personal Lighting on Vehicle Speeds in Nighttime Highway Preservation Projects
Multicontextual Machine-Learning Approach to Modeling Traffic Impact of Urban Highway Work Zones
Impact assessments of highway construction work zones (CWZs) are mandated for all federally funded highway infrastructure improvement projects. However, most existing approaches are ad hoc or project … [Read more...] about Multicontextual Machine-Learning Approach to Modeling Traffic Impact of Urban Highway Work Zones
Examination of the Current Practice of Lighting in Virginia: Nighttime Work Zones and Improving Safety Through the Development of Nighttime Lighting Specifications
This project evaluated current nighttime work zone lighting practices for limited-access highways and primary routes in Virginia through (1) an on-site evaluation of lighting levels in work zones; (2) … [Read more...] about Examination of the Current Practice of Lighting in Virginia: Nighttime Work Zones and Improving Safety Through the Development of Nighttime Lighting Specifications
