Many transportation agencies use accident frequencies, and statistical models of accidents
frequencies, as a basis for prioritizing highway safety improvements. However, the use of …

Most crash severity studies ignored severity correlations between driver–vehicle units
involved in the same crashes. Models without accounting for these within-crash correlations …

This research explores the injury severity of pedestrians in motor-vehicle crashes. It is
hypothesized that the variance of unobserved pedestrian characteristics increases with age …

Injury severities in traffic accidents are usually recorded on ordinal scales, and statistical
models have been applied to investigate the effects of driver factors, vehicle characteristics …

INTRODUCTION: Young male drivers are over-represented in traffic accidents; they were
involved in 14% of fatal accidents from 1991 to 2003 while holding only 8% of all drivers …

The influence of speed limits on roadway safety has been a subject of continuous debate in
the state of Indiana and nationwide. In Indiana, highway-related accidents result in about …

Motorcyclists tend to be more vulnerable to injuries than those using other motorised
vehicles and this may act synergistically with the complexity of conflicting movements …

Leaving the scene of a crash without reporting it is an offence in most countries and many
studies have been devoted to improving ways to identify hit-and-run vehicles and the drivers …

Research has suggested that motorcyclists involved in approach-turn crashes were much
more injurious than any other crash-type. This paper investigates the determinants of …

In this article, we develop a bivariate ordered Probit model to analyze the decision to fasten
the safety belt in a car and the resulting severity of accidents if it happens. The approach …
