Abstract

Aim: To determine whether local politicians influence the distribution of traffic calming measures.

Methods: Longitudinal ecological study in two UK cities. Local political constituencies were categorized by representation by members of the cabinet structure as a marker of influence. The density of traffic calming features per political area, adjusted for the historical pattern of road injuries, was compared between cabinet represented and non-represented areas.

Results: Traffic calming density was significantly associated with cabinet representation status, adjusted for historical collision risk (risk ratio 2.77, 95% confidence interval 1.37 to 5.61).

Conclusion: These results support the hypothesis that senior local politicians are effective advocates for enhancing safety in their areas.
