This report is based on the replies to the questionnaire on Risk Exposure Data (RED) that was sent to the national experts of all EU member states plus Norway. The present report can be seen as a first classification of the EU member states on RED availability, compatibility and usability. On the basis of these results, a clear distinction can be made between indicators that are at least generally available in Europe and indicators that are not generally available. There is a relation between availability and the level of complexity of the indicators. Basic indicators are more generally available than more complex ones.
The most widely available indicators are population, vehicle fleet, road length, fuel consumption, driver kilometres and vehicle kilometres. The less available indicators are: person kilometres, number of trips and time in traffic.
Based on examination of compatibility with CARE, five of the six generally available indicators are regarded as compatible with CARE. The only indicator that is not regarded as compatible with CARE is "fuel consumption". The main reason is that transport use can not be distinguished in the data collected in many countries. The other five indicators: population, driver population, vehicle fleet, road length and vehicle kilometres are regarded as compatible with CARE, or at least partially compatible.
These five indicators are thus regarded as usable. The other indicators are less than partially available or not compatible with the CARE data. However, this does not mean that these indicators are useless. They can still provide valuable information on national or small-scale international level. For European wide comparison these indicators are not (yet) suitable for usage in the common framework.
The five currently usable indicators are:
- Population
- Road length
- Vehicle fleet
- Driver population
- Vehicle kilometres
