Complementary Parametric Probit Regression and Nonparametric Classification Tree Modeling Approaches to Analyze Factors Affecting Severity of Work Zone Weather-Related Crashes
Identifying risk factors for road traffic injuries can be considered one of the main priorities of transportation agencies. More than 12,000 fatal work zone crashes were reported between 2000 and … [Read more...] about Complementary Parametric Probit Regression and Nonparametric Classification Tree Modeling Approaches to Analyze Factors Affecting Severity of Work Zone Weather-Related Crashes
Exploring Factors Contributing to Injury Severity at Work Zones Considering Adverse Weather Conditions
Despite recent efforts to improve work zone safety, the frequency and severity of crashes at work zones are still considerably high. The effect of work zones on traffic safety can be exacerbated by … [Read more...] about Exploring Factors Contributing to Injury Severity at Work Zones Considering Adverse Weather Conditions
Effects of Mounting Height, Offset Distance, and Number of Light Towers on Drivers’ Visual Performance and Discomfort Glare in Work Zones
Portable light towers are a significant source of glare to motorists entering a work zone. Although existing research has evaluated the effect of light tower orientation on visibility and glare, the … [Read more...] about Effects of Mounting Height, Offset Distance, and Number of Light Towers on Drivers’ Visual Performance and Discomfort Glare in Work Zones
Illumination and Visibility of Workers in Nighttime Highway Work Zones
Much of the construction work that occurs on high-speed roadways takes place at night to minimize impacts on drivers. Performing work at night exposes workers to hazards that are not present during … [Read more...] about Illumination and Visibility of Workers in Nighttime Highway Work Zones
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
