The potential of vehicle and road infrastructure interventions in fatal bicyclist accidents on Swedish roads-What can in-depth studies tell us?

The objective of this article is to describe the characteristics of fatal crashes with bicyclists on Swedish roads in rural and urban areas and to investigate the potential of bicycle helmets and different vehicle and road infrastructure interventions to prevent them. The study has a comprehensive approach to provide road authorities and vehicle manufacturers with recommendations for future priorities. The Swedish Transport Administration's (STA) in-depth database of fatal crashes was used for case-by-case analysis of fatal cycling accidents (2006-2016) on rural ( = 82) and urban ( = 102) roads.

Influence of crash pulse characteristics on injury risk in frontal impacts based on real-life crashes.

Objectives: In single-vehicle car crashes with roadside objects, one way to achieve low acceleration is to allow long duration by making objects more flexible. There is a lack of knowledge regarding the influence of long pulse duration on injury risk. The objectives were to study the influence of crash pulse characteristics on injury risk in frontal impacts and to study the correlation of these crash pulse characteristics, especially including crash pulse duration.

Risk of permanent medical impairment (RPMI) in road traffic accidents.

In addition to investigating risk of death due to road traffic injuries, there is a need to better describe the risk of serious consequences. This study assessed risk of permanent medical impairment based on road traffic injuries classified according to AIS-2005. Injured car occupants were followed for at least 5 years to assess permanent medical impairment.
