Vintervädrets betydelse för att fotgängare skadas i singelolyckor


The impact of the winter weather on injuries in single-pedestrian accidents have been studied using data from the Swedish emergency hospitals, and from the Swedish Transport Administration’s information system on roads weather. We have studied the winter seasons 2008/2009 until 2013/2014. The study’s purpose was to examine the weather that was prevailing at the time of the pedestrian injury and during the 24 hours before the accident. Two populations of single-pedestrian accidents have been analysed; all who have reported that slippery surface due to snow or ice was a contributing cause of the injury; all who have been injured in urban areas in the four selected municipalities: Umeå, Stockholm, Gothenburg and Malmö. A connection between the injury data and weather data were made both for the hours when the injury occurred, and for the 24-hour period prior to the injury. Compared to non-urban areas, in urban areas there were more than 10 times as many who were injured in single-pedestrian accidents due to slippery road condition (snow /ice). This study shows that female pedestrians are injured due to snowy or icy road surface to a greater extent than men. The females’ injuries are also more severe. When comparing the distribution of different accident causes between males and females an analysis of the odds ratio showed that males have a higher proportion of injuries due to snowy or icy road surface compared to females. Prioritizing maintenance on pedestrian and cycle paths during the winter season seems to be beneficial both in terms of injury reductions and in terms of costs for health care due to injuries from slipping on snowy / icy surfaces. The study indicates the possibility of using the weather data of the type used in this study as a tool in the planning and execution of winter maintenance.

Simulator used to practice emergency responses safely

Emergency responses of the police, ambulance, and rescue services are associated with a high risk of accidents, but practicing them in real traffic is neither safe nor permissible. A simulator-based method developed by the Swedish National Road and Transport...


Simulation of cut-in by manually driven vehicles in platooning scenarios

A study in a VTI-driving simulator has showed that a platoon will be able to handle a cut in from a manually driven car. The results of this study have recently been presented at two conferences in Japan.
