Hoyrisikogruppers Eksponering og Risiko i Trafikk. (Road Traffic Exposure and Risk Among High Risk Groups in Norway.)

摘要

The Norwegian Public Roads Administrations research programme on high risk groups in road traffic identifies five such groups: younger and older car drivers, drivers of motorcycles, foreign car drivers from non-western countries, and drivers driving under the influence of drugs or alcohol (DUI). There are many indications and also documentation revealing that these groups are more at risk than the average driver. The present study is based on a comprehensive survey to the different high-risk groups aiming to collect exposure data in order to give more detailed risk estimates for these groups than previously given. The results reveal that the risk figures of car drivers are quite similar to what is found in previous studies - younger and older drivers are more at risk than others. We find that the traffic volume of motorcycles is far less than what is generally assumed based on previous studies, and accordingly the estimated accident risk is higher. Especially young drivers (16-17 years) of light motor cycles are at high risk in Norwegian road traffic. Immigrant car drivers of a non-western origin are also more at risk than the average Norwegian car driver. In accordance with previous studies we find that DUI drivers are on average 55 times more at risk of having fatal accident than ordinary car drivers.
