Injuries

Severity Modeling of Work Zone Crashes in New Jersey Using Machine Learning Models

In the United States, the probability of work zone crashes has increased due to an increase in renovation works by transportation infrastructures. The severity of work zone crashes is associated with … [Read more...] about Severity Modeling of Work Zone Crashes in New Jersey Using Machine Learning Models

An Empirical Assessment on the Effects of Geometry and Non-Geometry Factors in Work-Zone Crashes With Unobserved Heterogeneity

Work zones are uniquely configured and managed by special traffic signs, standard channelizing devices, appropriate barriers, and pavement markings. Unexpected driving conditions through different … [Read more...] about An Empirical Assessment on the Effects of Geometry and Non-Geometry Factors in Work-Zone Crashes With Unobserved Heterogeneity

An Empirical Analysis of Driver Injury Severities in Work-Zone and Non-Work-Zone Crashes Involving Single-Vehicle Large Trucks

This study investigates the contributing factors influencing the driver injury severity of single, large truck crashes in work zones, as Florida ranks among the states with the highest rates of … [Read more...] about An Empirical Analysis of Driver Injury Severities in Work-Zone and Non-Work-Zone Crashes Involving Single-Vehicle Large Trucks

Assessment of Commercial Truck Driver Injury Severity Based on Truck Configuration Along a Mountainous Roadway Using Hierarchical Bayesian Random Intercept Approach

For the last decade, disaggregate modeling approach has been frequently practiced to analyze truck-involved crash injury severity. This included truck-involved crashes based on single and … [Read more...] about Assessment of Commercial Truck Driver Injury Severity Based on Truck Configuration Along a Mountainous Roadway Using Hierarchical Bayesian Random Intercept Approach

An Analysis of Motorcyclists’ Injury Severities in Work-Zone Crashes With Unobserved Heterogeneity

Work zone related crashes in Florida are increasing steadily in recent years. With such growing concern, work zone is recognized in Florida Strategic Highway Safety Plan. The severity and complexity … [Read more...] about An Analysis of Motorcyclists’ Injury Severities in Work-Zone Crashes With Unobserved Heterogeneity

Injury Severity of Truck-Involved Crashes in Work Zones on Rural and Urban Highways: Accounting for Unobserved Heterogeneity

Truck-related crashes in the work zones always resulted in severe injury outcomes. This paper analyses the injury severity of truck-involved crashes in the work zones based on a ten-year (2005–2014) … [Read more...] about Injury Severity of Truck-Involved Crashes in Work Zones on Rural and Urban Highways: Accounting for Unobserved Heterogeneity
