| Abstract Risk assessment and accident analysis methods based on systems thinking are currently popular, but few can be used together in an integrated manner. This article describes and demonstrates the Systems Thinking Accident and Risk Toolkit (START) which comprises the Networked Hazard Analysis and Risk Management System (Net-HARMS) risk assessment method, the Accident Network (AcciNet) accident analysis method, and the Safety Network (SafetyNet) intervention evaluation method. The three methods were designed to be used in an integrated manner as part of organisational safety management activities. START is described and demonstrated via a case study focussed on autonomous vehicles. The findings highlight the benefits of integrating risk assessment and accident analysis activities, including how accident data can be used to strengthen risk assessment outputs, and how the efficacy of specific risk controls can be considered in accident analysis efforts. Practical guidance on using the methods is offered, as well as recommendations for future research and applications in practice. |
