Applying the Systems Theoretic Accident Model and Process to Analyze a Downgrade-Truck Collision Caused by a Brake Failure in Vietnam

This present paper is to apply the Systems Theoretic Accident Model and Process (STAMP) and its corresponding the Causal Analysis using Systems Theory (CAST) as an innovative method to analyze a road traffic collision involving a goods vehicle travelling downhill ostensibly caused by a brake failure on a mountain road in Vietnam. The developed STAMP-CAST model of the collision under study showed that although driver’s inexperience, together with the truck’s low quality and severe road conditions were found as potential factors directly leading to the collision, the inadequate control actions of various actors residing at higher levels of the Vietnamese road transport system also contributed to the crash.
