Cykelfaktorer som påverkar huvudskador: simulerade omkullkörningar med cykel i VTI:s krocksäkerhetslaboratorium

In this project, single bicycle crashes have been simulated in the VTI crash safety laboratory. Crash tests including bicycles are scarce and when performed they usually simulate collisions with motor vehicles, although earlier studies have shown that cyclists are more frequently injured in single bicycle crashes. The objective of this study was to examine the influence of bicycle design and speed on the head impact when suffering from a single bicycle crash, and the possibility to study this using crash tests. In order to do that, two bicycle crash scenarios were simulated: “a sudden stop” and “sideways dislocation of the front wheel”; using four different bicycle types: a “lady’s bicycle”, a commuter bicycle, a recumbent and a pedelec; at two speeds: 15 and 25 kilometer per hour. In addition, sideway falls were performed with a bicycle standing still. All tests were done with a Hybrid II 50 percentile crash test dummy, with acceleration measurements in the head, placed in the saddle of the bicycles.
