Abstract
In order to obtain absolute measures of accident risk to children of different ages and sex when crossing different types of road, measures of exposure, which can be related to the accident statistics, are required. We have devised a suitable framework to achieve this which is presented here in detail. Measures of exposure were obtained from interviews with children and from traffic density counts on the roads they crossed in the previous 24 hours. The estimates of risk showed that the raw accident figures greatly underestimate the relative risk to children aged 5, 6 and 7 years, that the greater number of accidents to boys of this age is not due to their greater exposure to traffic, and that by the age of 8, boys, given their greater exposure, are no more at risk than girls.
