Fatality age was categorized as 21 to 29, 30 to 39, 40 to 49, 50 to 59, 60 to 69, or 70 and older, and road user was categorized as driver, passenger, or pedestrian. Estimated number of trips made by each age group was used to adjust for exposure and to measure individual risk. Fatalities recorded in Britain between 1989 and 2009. Population-wide fatal injury counts in Britain. Age of fatally injured drivers, passengers, and pedestrians. Estimated number of trips made per year by drivers, passengers, and pedestrians. Risk of fatal injury, but not fatality numbers in the population, were higher for older adult (≥ 70) drivers than for younger age groups. Risk of fatal injury was also high for older adult passengers and pedestrians, who represented the majority of older adult fatalities. Previous emphasis on driver impairment in older age has unduly focussed attention on elderly drivers, who represent a minority of all driver fatalities. Older adults represent a much larger proportion of passenger and pedestrian fatalities. Additional policy schemes and initiatives should be targeted at safeguarding older adult passengers and making the road environment safer for elderly pedestrians.

Although several case-control studies have been published, ecological analyses of head injury remain commonplace, presumably because of the availability of data and policy-makers’ preference for ‘whole population’ studies. Given that such population-level analysis will be conducted, this paper models the odds ratio between different road-user groups over time. We use a Bayesian implementation of a vector generalized additive model in order to examine the odds ratio for head injury when comparing male cyclists with female cyclists, male pedestrians with male cyclists, and female pedestrians with female cyclists over a period when helmet-wearing rates were thought to diverge by gender.
