  3. 3. Geography Matters (in a pandemic) SOCIAL DISTANCING METRICS QUANTIFYING RISK RISK INDEX CALCULATION
  4. 4. Current Social Distancing Metrics • Normalized by population • Some factor in distance traveled, while others are simply based on volume • Almost all factor out risk associated with volume • None quantify and identify significant grouping locations
  5. 5. Quantifying Risk Movement Risk Factors Movement Data Veraset human movement panel data (~5.6bil records per day) Unique mobile device location Analysis Environment Databricks ArcGIS

Risk Index Calculation Summarize Summarize Index Permutations •Home – movement origins •Trip – movement destinations Calculate Calculate risk index – multiply trip count by distance Sum Sum all home and trip location permutations Re-identify Identify home and trip location by device into h3 cells Bin Bin observations – H3 level nine hexagons Identify Identify dwell observations – drop high speed (over 1mph)
