The analysis illustrates how ABAA can contribute to a more detailed understanding of accident dynamics by reconstructing the temporal sequence of events and identifying organisational and design-related conditions that were not highlighted in the official investigation.

The existing evaluation methods fail to reveal the nonlinear relationship between vibration and comfort, ignoring the interpretability. This study proposes an interpretability comfort evaluation method using a hierarchical double path attention network (HDPA-Net). First, the acceleration and comfort data of the seat floor, cushion and backrest are collected through the road test. Then, the vibration transfer model and path decoupling method are utilised to identify vibration-sensitive paths. Finally, combined with a deep-learning model for comfort evaluation. The results showed that the multi-axis coupling has a significant impact on the transmission path. The HDPA-Net can capture vibration characteristics, achieving a mean absolute error of 3.3073 within a 0-100 score range, below the 10% acceptance threshold of ergonomics experts.
