In 2015, the District of Columbia framed a Vision Zero mission and action plan, with a target of achieving zero traffic fatalities by 2024. This study examines the impacts of Automated Speed Enforcement (ASE) and its role in achieving the goals of Vision Zero. Independent datasets containing detailed information about traffic crashes, ASE camera locations, and citation records, and driving speeds across the District's streets were collected, combined, and analyzed to identify patterns and trends in crashes, speed limit violations, and speeding behavior before and after the ASE camera installation. The results of this exploratory analysis confirm the safety benefits of ASE systems in Washington, D.C. The study also provides a blueprint for the different means of evaluating the short-term impact of ASE systems using different data sources which can aid practitioners in better evaluating existing systems and support the decision-making process regarding future installations.
