Mainstream books on experimental design in social science (e.g., Cook and Campbell, 1979) offer little to guide the process of research on large- scale problems like traffic safety. By drawing on experimental work, the author presents a comprehensive model to guide the process research in devel- loping proven, effective interventions to reduce accidents. Three reasons stand out for the failure of educational approaches: (1) focus on safety as attitude instead of behaviour; (2) choice of curriculum design as primary intervention tool; and (3) reliance on summative evaluation models employing group designs.
