District of Columbia Parking Violation Locations from December 2009

District of Columbia data provides geocoded parking citation locations for December 2009. The dataset summarizes ticket counts based on time of day, week, year, and violation category, as issued by the Metropolitan Police Department and partner agencies. Data was extracted from the eTIMS meter work order system and geocoded to street segment centroids.

Use Cases

• Analyze parking violation frequency by time of day and week of year to identify peak enforcement periods.
• Map geocoded citation locations to street segment centroids for spatial analysis of enforcement hotspots.
• Examine ticket counts by category of violation to understand common infraction types.
• Use summarized year and time data for temporal trend analysis of parking enforcement activity.

Strengths

• Data is geocoded to street segment centroids, enabling spatial visualization and analysis.
• Includes summarized counts across multiple temporal dimensions: time of day, week of year, and year.
• Covers violations from multiple enforcement agencies including MPD and DDOT.

Limitations

• Dataset is limited to a single month (December 2009), providing a narrow temporal snapshot.
• Data is summarized (ticket counts), not individual violation records, limiting granular analysis.
• Unknown sample size and row count prevent assessment of statistical significance.
