City logistics require an understanding of a number of issues that are seldom accounted for in current research. Policies may produce unsatisfactory results because behavioural and contextual aspects are not considered. Relevant data is crucial for forecasting the reactions of agents to policy changes. Despite recent methodological advances the development of appropriate survey instruments is still lacking to test policy acceptability. This paper expands and innovates the methodological literature by describing a stated ranking experiment to study freight agent interactive behaviour.
