Richmond Police Calls for Service and Traffic Stops

Richmond Police Department CAD Events detail calls for service, traffic stops, and pedestrian stops. The dataset includes event priority, disposition, location data, and unit dispatch and arrival timestamps. Records are provided by the Richmond Police Department and published via Transparent Richmond.

Use Cases

• Analyze response efficiency by calculating 'Dispatch-Arrival Time' across different eventPriority and Neighborhood Council Districts.
• Model eventType or secondaryEventType based on geographic features like streetblock, zipcode, and time of day from firstUnitDispatchDate.
• Identify spatial clusters of specific disposition codes using streetname and city fields for hotspot analysis.
• Correlate police activity metrics, such as call volume from cadAgencyEventNumber, with temporal patterns from createdDate.

Strengths

• Includes multiple event categories: calls for service, traffic stops, and pedestrian stops.
• Provides detailed temporal tracking with firstUnitDispatchDate, firstUnitArrivalDate, and createdDate columns.
• Contains granular location data with streetblock, streetname, city, state, zipcode, and Neighborhood Council Districts.

Limitations

• Sample size and total row count are unknown, limiting statistical reliability.
• Data completeness and potential null values in key columns like disposition or zipcode are unverified.
