“…An implication of the triangle, generally corroborated, was that an effective approach to preventing serious accidents is to monitor and reduce the occurrence of minor ones and the at-risk behaviors precipitating them. This principle has been a basis for behavior-based safety and, in trucking, onboard safety monitoring of driver behaviors (Pradhan et al, 2017;af Wåhlberg, 2008). Current thought in industrial safety, however, seems to be that Heinrich's Triangle has been oversold as a concept for reducing serious accidents.…”

The theoretical foundation of the Naturalistic Driving (ND) Mixed-Safety-Critical Event (SCE) methodology is found in the historical writings of H.W. Heinrich, a 20 th century industrial safety engineer. Heinrich espoused the theory that serious accidents, minor ones, and even no-injury operator errors all had identical or highly similar causal mechanisms and that accident consequences were essentially unlinked to causes. This became the basis for today's ND Mixed-SCE method, whereby a variety of mostly non-crash avoidance maneuvers (e.g., hard braking, swerves) and other kinematic events (e.g., lane drifts) are aggregated by researchers to form a dependent variable dataset ostensibly representative of important and harmful crashes. This paper examines this approach and finds it to be invalidated by the pervasive causal heterogeneity of crashes and would-be surrogates. Crashes are heterogeneous horizontally by type and vertically by severity. This paper argues instead for the heterogeneity principle as the foundational assumption and guiding tenet for any effort to extrapolate causal evidence from surrogates (e.g., non-crashes or minor crashes) to a different and more important target crash population such as serious crashes.
