The Application of a Systems Thinking Design Toolkit to Improve Situation Awareness and Safety at Road Intersections

摘要

Incompatibility in situation awareness at intersections has been identified as playing a role in road crashes. One of the key factors underpinning these incompatibilities is the design of the road environment. In this study, findings from the analysis of road user situation awareness using schema theory, event analysis of systemic teamwork and cognitive work analysis were used within a participatory design process involving the Cognitive Work Analysis Design Toolkit (CWA-DT) to generate new design concepts. This paper provides a summary of the design process and outcomes as well as findings from an evaluation of the CWA-DT based on participants’ subjective experience of the process.
