# SF Taxi Mobility Equity Dashboard
An interactive Plotly Dash dashboard analyzing spatial equity in San Francisco taxi services. Compares **Street-Hail** vs **App-Based** trip patterns across SF's 41 Analysis Neighborhoods and evaluates service representation relative to demographic baselines using Representative Ratios.
