Title:

Analysis of Injury Severity in Heavy Vehicles Angle Crashes

Accession Number:

01623768

Record Type:

Component

Abstract:

Crashes involving heavy vehicles are a major road safety concern because of the higher likelihood of fatal and serious injury outcomes. The primary objective of this research is to identify the factors contributing to injury severity in angle crashes involving heavy vehicles. The skewed logistic (Scobit) model is applied to data on two-vehicle angle collisions in Victoria, Australia because of the imbalance or skewness in the injury outcomes. The authors find that the skewed logit model performs better than the standard binary logit model due to the violation of the symmetry assumption. The factors influencing injury severity in angle crashes involving heavy vehicles include occupants' gender, age and restraint use, vehicles' age, type, movement, fire status, point-of-impact and damage, time-of-day, road classification, posted speed limit, intersection type, and number of occupants involved.
