Taking a mixed-methods approach to collision investigation: AcciMap, STAMP-CAST and PCM
Recently, ergonomics and safety researchers have turned their attention towards applying combinations of sociotechnical methods rather than using single methods in isolation. In the current research, a mixed-method approach combining two systems-based methods, Accimaps and the Systems Theoretic Accident Model and Process - Causal Analysis using Systems Theory (STAMP-CAST), and one cognitive approach, the Perceptual Cycle Model (PCM), were employed in analysing a rail-level crossing incident in Bangladesh. Each method was applied individually to investigate the collision, and interventions were proposed corresponding to incident events at different risk management framework levels. The three methods provided different perspectives of the whole picture, together identifying an array of contributory factors. The complementary nature of these methods aided in proposing a comprehensive set of safety recommendations, thereby demonstrating the benefit of a mixed-method approach for collision investigation in low-income settings.

Abstract
Recently, ergonomics and safety researchers have turned their attention towards applying combinations of sociotechnical methods rather than using single methods in isolation. In the current research, a mixed-method approach combining two systems-based methods, Accimaps and the Systems Theoretic Accident Model and Process - Causal Analysis using Systems Theory (STAMP-CAST), and one cognitive approach, the Perceptual Cycle Model (PCM), were employed in analysing a rail-level crossing incident in Bangladesh. Each method was applied individually to investigate the collision, and interventions were proposed corresponding to incident events at different risk management framework levels. The three methods provided different perspectives of the whole picture, together identifying an array of contributory factors. The complementary nature of these methods aided in proposing a comprehensive set of safety recommendations, thereby demonstrating the benefit of a mixed-method approach for collision investigation in low-income settings.

In total, STAMP-CAST gave rise to 36 recommendations, Accimap to 24 recommendations, and the PCM analysis to 10 recommendations. The frequency of recommendations proposed at different levels of the system, separated by analysis method, is shown in Fig. 8. The PCM analysis supported recommendations for interventions at only the bottom two levels, as would be expected given its focus on human performance. Also as expected, given their higher-level focus, both Accimap and STAMP-CAST analyses supported the proposal of recommendations at the upper levels as well as at the lower levels of the system.Because of the existence of a failure taxonomy in STAMP-CAST, it was the only model that supported identification of interventions related to feedback mechanisms between system levels. Even though the Accimap can include both control and feedback mechanisms, its lack of taxonomy makes this method more dependent on the judgement of the analyst (Stanton et al., 2019). This can result in the non-identification of feedback failures, as evident from the analysis presented above. We therefore echo Salmon and Read (2019) recommendation that both are used together.This research was funded by the National Institute for Health Research (NIHR; 16/137/122) using UK aid from the UK Government to support global health research.
