Also, the age group of 80+ is the fastest growing population group and at the same time has the highest KSI (killed and seriously injured) rate leading to a strong need to focus on improving safety measures especially for this group. In each of them over 40% of casualties aged 65-69 were car drivers or passengers, but the proportion of car users decreases as age increases (Figure7.2). Thus, a much larger proportion of casualties in the 80+ age group were pedestrians.
