Scoring system

Killed or seriously injured (KSI) is a standard metric for safety policy, particularly in transportation and road safety.

ISO 39001 considers a serious injury as having an impact on the body or on the capacity of an individual.

Killed: The usual international definition, as adopted by the Vienna Convention in 1968 is 'A human casualty who dies within 30 days after the collision due to injuries received in the crash'. Serious injury: The definition is less clear cut and may vary more over time and in different places. The UK definition covers injury resulting in a person being detained in hospital as an in patient, in addition all injuries causing: fractures, concussion, internal injuries, crushings, burns (excluding friction burns), severe cuts, severe general shock which require medical treatment even if this does not result in a stay in hospital as an in patient. Slight injury: Sprain (including neck whiplash injury), bruising or cuts which are not judged to be severe. Also slight shock requiring roadside assistance.

Killed: The usual international definition, as adopted by the Vienna Convention in 1968 is 'a human casualty who dies within 30 days after the collision due to injuries received in the crash'. This new concept is based on MAIS (from the English Maximum Abbreviated Injury Scale). Based on this standard, serious injuries are defined as scale 3 and more (or MAIS3+). In 2014, 135,000 people were seriously injured on Europe's roads.

Figures for fatalities are normally highly reliable in industrialised countries and few if any fatalities go unrecorded. Fatality figures are however often too low making it hard to see trends over time for one place. Figures for the number of people seriously injured typically being an order of magnitude larger than the number of people killed and are therefore more likely to be statistically significant. However, classification of serious injuries is open to opinion, by medical staff or by non medical professionals, such as police officers and may therefore vary over time and between places. Figures for slight injuries are considered highly unreliable, largely due to under reporting where injuries are self treated

Several metrics are derived from KSI metrics, with various goals such as international comparison which need normalization. Fatalities per capita This metric allow to compare countries, whatever the size of their population. It us used by OECD and in Europe. It allows to compare countries similar in their development. It can be considered as a health risk. It can be computed on regional / local level. Fatalities per vehicle kilometres This indicator is related to assessment of the travel risk on a given road network. Only 22 IRTAD countries produce such a metric. It allows comparison with other transportation mode or to compare road networks. Fatalities per registered vehicles This indicator is more easily available than fatalities per vehicle kilometres, that it might help to compare nations, taking into account both their size and their level of development. The 28 EU 28 countries, for the 28 members, computed an indicator named "per 10 billion pkm". Pkm is an indicator of traffic volume which is used for not having consistent vehicle kilometre data. Are counted cars and estimated motorised two wheelers. In 2016, this indicator ranges from 23 for Sweden to 192 for Romania, with a value of 52 for the EU 28. In Germany, France, the UK and Italy, this score is respectively 33, 46, 28, 44.
