Overview

The Puget Sound Traffic Citations Map visualizes the distribution of traffic violations across Seattle and the broader Puget Sound region. It uses point-based citation data symbolized as a heat map to highlight locations with higher concentrations of traffic violations.

Data Source

• CitationLocations Feature Class from the SeattleCitations geodatabase.
• Data provided by the Washington State Traffic Council.
• Attributes include violation type, county, and milepost location.

Puget Sound Traffic Violations Hotspots

• The I-5 corridor between Everett and Olympia shows the highest density of traffic violations.
• King County has the largest number of citations compared to surrounding counties.
