Influences of vehicle properties on road traffic accidents

May 19, 2014
Based on a newly created pool containing data of the Road Traffic Accident Register, other registers of the Swiss Federal Roads Office as well as from various other data sources, the influence of vehicle properties on road accidents are being examined: Passenger cars are involved in an accident every 900'000 km on average and take part in the vast majority of all accidents on Swiss roads. Trams show a comperatively high accident rate, however, they are mostly operating in heavy traffic in urban areas where interactions with other road users are frequent. Trams are very rarely identified as the responsible party in accidents. Also high accident rates are observed with e-bikes (pedelecs). Compared to conventional bicycles their accident rates are considerably higher. The accident rates of motorcycles are more than twice as high as the ones of passenger cars.
