In-depth, retrospective accident investigation studies provide a means to understand how car occupants are injured in road traffic accidents. In most retrospective studies, crash severity is estimated using the CRASH3 computer program. capable of crash severity assessment, PC-CRASH is more focused on accident reconstruction, and is therefore not discussed in this paper. AiDamage is a crash seve...

OBJECTIVE To investigate whether the risk of motorcycle crash related injuries is associated with the conspicuity of the driver or vehicle. DESIGN Population based case-control study. SETTING Auckland region of New Zealand from February 1993 to February 1996. PARTICIPANTS 463 motorcycle drivers (cases) involved in crashes leading to hospital treatment or death; 1233 motorcycle drivers (co...

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...

For the assessment of vehicle safety in frontal collisions, the crash compatibility between the colliding vehicles is crucial. Compatibility compromises both the self protection and the partner protection properties of vehicles. For the accident data analysis, the CCIS (GB) and GIDAS (DE) in-depth data bases were used. Selection criteria were frontal car accidents with car in compliance with EC...

The objective of this study is to investigate the effects of obesity on occupant responses in frontal crashes using whole-body human finite element (FE) models representing occupants with different obesity levels. In this study, the geometry of THUMS 4 midsize male model was varied using mesh morphing techniques with target geometries defined by statistical models of external body contour and e...

Vehicle frontal crashworthiness analysis is an important topic in the field automotive community, as it relates to legislative requirements. Frontal crash models contain a large number of elements and therefore present high computational cost, especially when performing structural performance optimisations. A new numerical methodology proposed this paper with aim increase computation speed by i...
