Who gets in the most accidents?

accidents by user

The above graph shows the number accidents involving each type of road users. Note that some accidents involved more than one type of road user and thus could be counted more than once (N=1339).

Although private cars are the type of vehicle most often in an accident, when taking into account the number of people affected by a single accident, PSVs affect the most people because they carry the most. In the graph below a conservative estimate of five passengers is used to demonstrate the comparative effect of PSV accidents versus those involving other road users.estimated affected users
