Demographic estimates show that in 2015 one fifth and in 2030 one quarter of the population in Finland will be over 65 years old. With regard to elderly people one objective in social policy is that they could lead an independent life and live at home. A central requirement for independent life of elderly people is to support their mobility, which is also productive in terms of national health and national economy.

In relation to the number of elderly people, they are more often involved in serious traffic accidents than other road user groups. The consequences of accidents are more severe to older people as ageing makes the body more vulnerable to injuries and the healing process longer.
