It has been assumed that risk perception can be an important factor for the explanation of travel behaviour. However, the results to support this are few, outdated and from an American car dependent travel culture. It has been suggested in a number of risk perception studies that affective assessments are a stronger predictor of behaviour than cognitions about probability. The current cross national study (N= 2650) aimed to study the influence of risk, either measured as perceived probability or as fear, on behaviour. The context of the study is a range of different modes of transport, hence risk is operationalised both as accident risk and as risk of crime/violations. The results show that perceived risk might influence our decisions about how and where to travel, and that fear is a better predictor of behaviour than perceived probability in both countries. Whether our general mobility is influenced by perceptions about accidents or other threats is still an open question. Differences and similarities between Norway and France are discussed.
