Accident causation and pre-accidental driving situations: Part 1. Overview and general statistics
WP2 of the European Project TRACE is concerned with âTypes of Situationsâ 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 âdescriptive analysisâ which from general statistics will allow to identify among the studied
situations those them relevant and to give their characteristics, the âin-depth analysisâ 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 âinâdepthâ 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
Accident causation and pre-accidental driving situations. Part 3. Summary report
This report aims to present the final results of the descriptive statistical, in-depth and risk analysis
performed within TRACE Work Package âWP2-Type of situationsâ, in order to identify the main
problems and the magnitude of these problems related to accident causation and risk factors for
the following four types of situations: the stabilized situations, the specific manoeuvres, the
intersection situations and the degraded situations.
The different analysis (descriptive, in-depth and risk) of each of these five tasks has been
performed using the available European accident databases within TRACE (national, in-depth
and exposure databases).
The objectives achieved in this WP are:
⢠Identify and quantify accident causation factors associated to particular types of driving and
pre-accidental situations, at a statistical level, by analyzing various available databases in
Europe.
⢠Obtain a focused understanding of accident causation issues related to these types of
situations at an in-depth level by analyzing data from available in-depth databases.
⢠Identify the level of risk associated to these selected types of situation in causing accidents
Accident causation and pre-accidental driving situations. Part 2. In-depth accident causation analysis
WP2 of the European Project TRACE is concerned with âTypes of Situationsâ 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 âdescriptive analysisâ which from general statistics will allow to identify among the studied
situations those them relevant and to give their characteristics, the âin-depth analysisâ 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 âinâdepthâ level. This report is dedicated to the identification of the accident causes
analysed for the pre-accidental driving situation point of view, i.e. the circumstances in which the
driver is involved just prior the accident. This analysis has been conducted from the scenarios
identified for each type of situation during the descriptive analysis realized in a first part (Report D2.1:
Accident causation and pre-accidental driving situations. Part 1. Overview and general statistics).
These results are based on the study of disaggregated data (in-depth accidents collection databases)
available via WP8 in TRACE. With the identification of the main causes and contributing factor, the
aspect related to the human functional failure has been taken into account. This innovative concept
studied in TRACE WP5, has been used here in order to have a more complete overview of the
problems in working on each road users involved in the accident and not only on the whole accident
