THE ROADS4ALL FRAMEWORK FOR TRAFFIC SAFETY CULTURE AND MULTILEVEL INTERVENTION DESIGN

Traffic safety culture offers a perspective on the shared values, beliefs, attitudes and norms through which actors understand and enact road safety. Translating this perspective into intervention design requires a clear connection between system conditions, cultural processes and road user behaviour. This paper presents the qualitative-integrative component of the Roads4All framework, developed through a synthesis of existing approaches and refined through an interdisciplinary expert consultation. The framework combines a multilevel system perspective with a behavioural pathway perspective. It distinguishes micro-, meso-, macro- and magna-level influences and treats shared safety-related cognitions as the cultural core, while recognising reciprocal relationships with behaviour and contextual conditions. A hypothetical fleet-speeding example illustrates how practitioners can identify intervention levels, formulate mechanisms and distinguish behavioural outcomes from cultural change. The framework provides a structure for developing context-sensitive intervention hypotheses and complementary measures. It does not establish causal effects or demonstrate intervention effectiveness. Future research should operationalise group-level cultural constructs and examine the proposed relationships through longitudinal and intervention studies.
