Decoding Elevator Accidents: Insights from Trajectory Intersection Theory

Elevator-related accidents, though infrequent, can have severe consequences. To comprehend and mitigate the underlying causes, this research delves deep into the realm of the Trajectory Intersection Theory. By systematically analyzing national safety bulletins concerning special equipment over the past decade, we discerned patterns and trends in elevator mishaps. Further investigation into 20 emblematic elevator accident reports shed light on the predominant causative factors. The Trajectory Intersection Theory provided a robust framework, enabling the formulation of a comprehensive model that addresses both human and materialistic determinants. This model, spanning the entire lifecycle of an elevator, offers invaluable insights into the phases of transitional operation, break-in, stability, and decline. Drawing from these analyses, we chart a strategic pathway for proactive elevator risk management, centering on accident prevention.
