Abstract:
The use of bicycles as a mean of healthy and eco-friendly transportation is currently actively promoted in many industrialized countries. However, the number of severe bicycle accidents rose significantly in Germany and Canada in 2011. In order to identify risk factors for bicycle accidents and possible means of prevention, a study was initiated that analyses bicycle accidents from selected regions in both countries. Due to different healthcare systems and regulations, the data must be selected in different ways in each country before it can be analyzed. Data is collected by means of questionnaires in Germany and using hybrid electronic-paper records in Canada. Using this method, all relevant data can be collected in both countries.
