Exposure data and risk indicators for safety performance assessment in Europe.

Highlights: [•] The concepts of exposure and risk and the theoretical properties of various exposure measures are explored. [•] The methods for collecting disaggregate exposure data at national level are presented. [•] A common European framework for the collection and exploitation of exposure data is lacking. [•] Road safety performance assessment in Europe can be based on the exposure data available in the IDFs under certain conditions. [•] Steps for the improvement of the potential for analysis in the short and in the long term are proposed. [ABSTRACT FROM AUTHOR]
