National accident statistics make a study of the main characteristics of the vehicles and drivers involved in accidents but risk exposure must be taken into account. The author describes a study in France where the distance travelled and the journey speeds were analysed for characteristic groups of driver vehicle or journey variables to give a basis for the evaluation of risks. A multidimensional approach was then used to highlight homogeneous groups of distances travelled and the relations between the different variables. A relative accident risk per unit distance was estimated for certain categories where data was available. Results showed most trips to be short (5 km or less) with journey speed increasing with journey length. Journeys to work and associated with work accounted for 30 per cent of distance travelled. Trips by men were characterised more by professional or leisure motivation than those by women. Mobility is closely linked to the income of the household and type of vehicle, newer vehicles are used more than older vehicles. Women were found to travel at the same speed as men on journeys. The relative risk of being involved in an accident was high between midnight and 3 am. Age was a dominant risk variable with the highest risks among young people. Vehicles over 10 years old have a higher risk of accident, partly because many are driven by young drivers.
