Abstract: The identification of traffic behavior patterns of individuals involved in road traffic accidents is an important part of the comprehensive identification of road traffic accident traces and physical evidence, which involves interdisciplinary knowledge. Typical traffic injuries, trace evidence, and trajectories with distinct characteristics serve as significant pieces of evidence to determine such manner of action and provide definitive opinions. In road traffic accidents, individuals suffer injuries of varying degrees from vehicle collisions. By analyzing the morphology and mechanisms of these injuries, it is possible to objectively determine the manner of action of the parties involved. Typical traffic injuries, in particular, play a critical role as evidence in these cases. This study aims to explore how to identify and utilize crucial evidence by examining and summarizing the morphology and injury mechanisms, and introduces identification practice of ten typical types of traffic injuries. The ultimate goal is to comprehensively determine manner of action of individuals involved in accidents combined with eligible conditions, and provide reference for future forensic appraisal practices in this area.

Key words: road traffic accident, manner of action in road traffic accident, typical traffic injuries, critical evidence, identification and utilization

摘要： 道路交通事故涉案者交通行为方式鉴定是道路交通事故痕迹物证综合鉴定的重要内容，其涉及多学科交叉知识。具有认定交通行为方式的典型特征损伤、痕迹物证和运动轨迹可作为交通行为方式判断的关键性依据，能够得出认定性的意见。在道路交通事故中，因车辆碰撞造成涉案者不同程度的损伤，通过损伤的形态及对损伤机制的分析，能够客观地判断涉案者的交通行为方式。其中，典型特征损伤更是起到了关键证据的作用。通过梳理、归纳十种常见典型特征损伤的形态、致伤方式及鉴定实践，探讨如何辨识和运用典型特征损伤的关键证据；结合符合性成立条件，综合判断涉案者交通行为方式，以期对司法鉴定实践提供参考。
