Kollisioner och olyckor med rådjur i Sverige under 10 år (2003–2012): variation i tid, geografi och kostnader

Annika K Jägerbrand

The goal for this project was to create a 10-year overview of the number of deer collisions in Sweden and accidents variation in time, geography and cost, both in terms of property damage and personal injuries. Accident statistics were gathered from NVR (National Wildlife Accident Council, data on collisions), Strada (fatalities and injuries in Swedish Traffic Accident Data Acquisition) and Ofelia (collisions at railway). The results show that the number of deer collisions has increased over the 10-year period and that the increase has been much greater in the northernmost counties and Gotland. The number of deer collisions is higher during the early summer (May–June) and winter (October–December), whereas the number of fatalities and injury accidents is highest during the summer. The number of deer collisions varies during the day, but most accidents occur in the morning and evening for both property damage and personal injury accidents. For fatalities in accidents with roe deer, there are more than twice as many compared to the officially reported numbers, and the number of serious injuries is 177% higher than the official records. It is likely that the official statistics are also underestimating the number of fatalities and injuries from wildlife accidents caused by moose, deer and wild boar. This study shows that the total cost of roe deer collisions and accidents in 2012 exceeds 1 billion SEK, of which approximately 70% account for the cost of property damage.

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.
