Several indicators aim to illustrate the impact of traffic crashes. The most common ones are the number of fatalities and injuries. Globally some 1.3 million people die on the road every year and up to 50 million suffer injuries. And overall economic costs of road crashes range from 2-5 percent of GDP in many countries. These economic costs provide a basis for transport safety improvement projects such as hazard location treatments, road audits, school zones and other preventive measures.
It is important, however, to turn our eyes on the impact of road crashes at the household level. The impact on a family in losing a loved one is enormous, both in terms of emotional trauma and/or loss of income or caused disability, especially when many poor countries do not have strong enough safety nets for victims of road crashes. The impact of road crashes is less understood, and lack of strong data or evidence on these is a challenge in many countries.
If a member of a family is involved in a road crash, what kind of changes are likely to occur in that particular family? If the head of household or breadwinner is killed or severely injured, the impact to that household can be devastating. There are scarcely plausible surveys that show the effects of road crashes on households because it is presumably difficult to trace victims of road crashes.
