STUDY OBJECTIVES Sleep-related complaints are common in adolescents, but their impact on the rate of motor vehicle crashes accidents is poorly known. We studied subjective sleep quality, driving habits, and self-reported car crashes in high-school adolescents. METHODS Self-administered questionnaires (with items exploring driving habits) were distributed to 339 students who had a driver's lic...

In the development of a crashworthy road transport system, guard-rails could play an important role in preventing frontal collisions on roads without separated lanes and in avoiding collisions with roadside objects. Crash pulses in crashes into guard rails may differ from e.g. car-to-car collisions, concerning the duration and mean acceleration. If the characteristics of crash pulses into guard...

The aim was to study the influence of new car design on the distribution and disability risk of injuries to different body regions. The cars were categorised in 5-year periods according to year of introduction. The injuries of 11,535 injured car occupants, as well as 42,228 two-car crashes reported by the police between 1994 and 2000, were used. Comparing car models introduced in 1980-84 with m...

Vehicular injury is one of the main reasons for traumatic injuries. Finite Element Human Body Models (FEHBM) have become very popular to assess car crashes and the subsequent injuries. It provides the possibility to predict stress and strain values in tissue level by representing anatomical structures in details. An essential requirement for the FEHBM is to exhibit human-life response, i.e. bei...

OBJECTIVE Direction of injury force inferred from pelvic radiographs may be used in trauma care to predict associated injuries and guide intervention. Our objective was to compare injury direction determined from anteroposterior (AP) pelvic radiographs with injury forces determined from crash site investigation. MATERIALS AND METHODS We studied all 28 subjects from the Crash Injury Research E...

This paper investigates the relationship between a passenger car's year of registration and its crashworthiness and aggressivity in real-world crashes. Crashworthiness is defined as the ability of a car to protect its own occupants, and has been evaluated in single and two-car crashes. Aggressivity is defined as the ability to protect users travelling in other vehicles, and has been evaluated o...

The current study contributes to the existing injury severity modeling literature by developing a multivariate probit model of injury severity and seat belt use decisions of both drivers involved in two-vehicle crashes. The modeling approach enables the joint modeling of the injury severity of multiple individuals involved in a crash, while also recognizing the endogeneity of seat belt use in p...
