This Shiny application was developed for ADFC Mannheim to visualize and explore traffic accident data in Mannheim, Germany. The app allows users to interactively filter accidents by year and severity, using an intuitive, color-coded map interface.
This tool supports Vision Zero — the goal of eliminating all traffic fatalities and severe injuries — by making accident data accessible for public advocacy, urban planning, and community awareness.
