Car, aeroplane and train travel have different risk characteristics th
at influence the safety ranking between them. The ranking depends on t
he range of distances compared. It also depends on what we mean by ris
k. Three reasonable interpretations of risk are presented. They are ap
plied to Swedish transportation statistics. The results reveal that th
ere is a safety niche for each of the three alternatives. That is, car
, aeroplane and train each have a certain claim to being the safest me
ans of transportation. Copyright (C) 1996 Elsevier Science Ltd
