摘要:AbstractItaly shows the European primacy in number of powered two-wheelers fatalities (PTW), which accounts for 30% of the total, compared to the 17% of the EU average. PTWs are the most vulnerable of powered transport modes because of their lack of safety devices and the absence of a protecting chassis for drivers and passengers. Drawing on ISTAT database, a logistic regression was carried out, in order to identify factors affecting crash severity. The analysis of the results partially confirmed previous international studies and added new knowledge about the causes of injury severity in PTW crashes in Italy.
