WP2 of the European Project TRACE is concerned with “Types of Situations” to analyse the causation
of road traffic accidents from the pre-accidental driving situation point of view. Four complementary
situations were defined: stabilized situations, intersection, specific manoeuvre and degradation
scenario. To reach this objective, the analysis is based on a common methodology composed on 3
steps: the “descriptive analysis” which from general statistics will allow to identify among the studied
situations those them relevant and to give their characteristics, the “in-depth analysis” allowing to
obtain accident causes from the generic description of the problems identified in the previous step and
the risk analysis identifying the risk of being involved in an accident taking into account the results
obtained from the ‘in–depth’ level.
This report is dedicated to the descriptive analysis with the identification of the most relevant scenario
regarding the situation in which the driver is involved just prior the accident. The results are based on
the literature review, general statistics and the analysis of the national databases available in TRACE
via WP8. Because the information level differ from databases to another, the available scenario
presented here for the 4 predefined types of situations are generics and some specific situations could
not have be distinguished. For each situation some key indicators are given, such as prevalence,
severity, KSI (killed x severely injured), etc. When it is possible, these indicators are estimated at the
EU27 level
