6 Collision accident analysis
6.1 Confidence analysis of collision accident information
6.1.1 The types of collision accident information should be classified according to the
following dimensions.

transportation, industry and information technology, emergency, market
supervision and management, enterprises, individuals, etc.;
- According to the information source object, such as the road environment
information at the collision accident site (basic road environment information, road
traces, roadside video, friction coefficient, slope, etc.), accident vehicle
information (vehicle damage, vehicle traces, vehicle video, vehicle data, other non-
traffic accident vehicle record data related to the accident on the road, etc.),
accident personnel information, etc. (statements, witnesses, injuries, etc.);
- According to the information time and space dimension, such as collision accident
site information, post-site information, vehicle historical operation and
maintenance information, personnel historical symptoms, etc.;
- According to the information acquisition method, directly survey/read the
information obtained, deduce and calculate the information obtained;
- According to other methods.
6.1.2 To ensure the reliability of collision accident information, it should obtain the
vehicle operation data of the enterprise platform through a third-party platform
approved by relevant government departments, or through a recall technical agency or
an authorized professional agency; use it after matching and verifying with the accident
vehicle data.
6.1.3 After completing the collection of collision accident information, before
conducting analysis, it should conduct a confidence analysis of the collision accident
information; classify the multi-source collision accident information according to the
confidence level; give priority to the collision accident information with higher
confidence.
6.1.4 The degree of confidence of collision accident information should be graded,
according to the reliability and directness of its source and whether it can be objectively
verified.
- High degree of confidence, which is first-hand direct, specific and reliable
information, such as on-site surveillance video reflecting the collision process, on-
site traces, accident data recorder, forensic report, etc.;
- Medium degree of confidence, which is incomplete, indirect or information that
requires further verification, such as testimony, incomplete surveillance video,
damaged physical evidence, background vehicle operation information, etc.;
- Low degree of confidence, which is subjective speculation, vague clues and other
information that is difficult to verify, such as testimony under conditions of loss of
consciousness or confusion, testimony without civil liability, information on social
media, unverified third-party reports, etc.
6.1.5 The accident information with medium and low degree of confidence shall be
compared and verified with the high confidence accident information; the verified
reliable parts shall be extracted for collision vehicle accident analysis.
6.1.6 It should adopt methods such as reproduction test, function replay, simulation,
calculation derivation, comparison analysis, etc., to verify the accident information.
6.2 Accident process analysis
6.2.1 The accident process analysis can only be carried out, after the confidence analysis
and verification of the collision accident information.
6.2.2 The accident process analysis mainly outlines the time and space process of the
accident, by clarifying the kinematic and dynamic sequences of the accident
participants before, during and after the collision; understands the overall picture of the
accident.
6.2.3 For the analysis of the collision accident process of road vehicles with driving
automation functions, it should use the accident process video, electronic data, traces,
personnel and other information in combination, to mark the time nodes of key events
in the accident process, such as vehicle start, acceleration, steering, takeover/trusteeship,
collision or emergency braking, emergency response, etc. Systematically simulate the
perception, decision-making and execution process of the driver or driving automation
system to analyze the entire process of the accident.
6.2.4 The accident process analysis mainly analyzes the relationship between the traffic
behavior of the accident participants and the cause of the accident, providing key
functional deviation analysis, other problem analysis.

problems of vehicle technical failure, vehicle human-machine interaction, vehicle
functional deviation through comprehensive information, further analyze whether the
technical problem is other vehicle problems.
7.6 Vehicle safety defect risk analysis
When multiple collision accidents occur in the same batch and model vehicles due to
the same type of vehicle safety problems, combined with the above-mentioned collision
accident vehicle investigation and vehicle safety analysis results, it should further
conduct vehicle product safety defect risk assessment and analysis, in accordance with
GB/T 34402-2017; give conclusions in the following three aspects.
