Abstract

In the analysis of two-wheeler traffic accident patterns, a three-dimensional integrated identification system for driver-passenger relationships, namely “trace–motion–injury”, is established through systematic analysis of core elements such as the motion state of two-wheelers, distribution patterns of traces, the relationship between receiving surfaces and trace-forming objects, injury mechanisms and causative instruments. The entire accident process is reconstructed based on kinematic principles, with kinematic analysis as the core to achieve dynamic reconstruction of the full accident sequence. Combined with the structural characteristics and operational features of two-wheelers, multi-dimensional fitting is carried out from the perspectives of trace formation mechanism, vehicle running trajectory and injury formation logic, thereby realizing precise trace examination and correlation verification. Finally, the actual rider of the two-wheeler is scientifically determined. This method proposes a multi-dimensional fitting identification approach, providing reliable technical support and practical reference for the identification of driver-passenger relationships in complex two-wheeler traffic accidents.
