PEDESTRIANS AT RISK

In urban areas in the UK about three quarters of road accident costs arise from injuries to vulnerable users, of which pedestrians form the largest group. Whilst the distribution of these accidents with respect to type of road and crossing facility is known, there is a dearth of information regarding the exposure of pedestrians to risk in different circumstances, and the critical aspects of the interaction between road users. Risk of a road accident is typically expressed relative to the amount of travel, e.g. accidents per vehicle km is a commonly used measure. Here vehicle km is the unit of exposure, and risk is expressed as an accident rate per unit of exposure. Such statistical measures of risk are often very different from perceived risk. The choice of denominator in specifying an accident rate which describes pedestrian exposure to risk is crucial. Unfortunately we have little information about pedestrian travel and activities, thus it is difficult to reach informed decisions about pedestrian risk in different circumstances and about the value of different countermeasures. This absence of information sets the context for the research which Ross Silcock Limited has recently carried out for the Department of the Environment, Transport and the Regions, focusing on pedestrian behaviour and exposure to risk in crossing urban roads. The paper presents the results of this work, showing how pedestrian exposure to risk varies by crossing location, by age/sex and with respect to aspects of behaviour. For the covering abstract, see IRRD E101115.
