Traffic collisions remain a leading cause of preventable death and injury in Canada and North America. Vulnerable Road Users (VRUs), pedestrians, cyclists, and motorcyclists, are disproportionately affected, with their share of fatalities rising from since 2010. Despite widespread adoption of Vision Zero strategies aimed at eliminating traffic deaths through systemic design changes, rigorous population-level evaluations of these interventions are lacking. Current studies often rely on simple pre-post designs, which fail to account for temporal trends, regression to the mean, and time-varying confounders such as traffic volume and road user composition. Additionally, municipal records frequently lack precise data on intervention dates and locations, hindering robust analyses. This talk will highlight these gaps while discussing several avenues to tackle them.
