Developing effective transportation safety programs for tribal lands is important due to higher crash rates and crash severities in those areas. Correspondingly, a comprehensive tribal crash reporting and crash data quality are imperative to analyze and identify high crash locations and to develop and fund effective tribal safety programs. This study presents quantitative and spatial data analyses to validate the effectiveness of tribal crash data elements on the Wisconsin police crash report with respect to three attributes: location, jurisdiction, and law enforcement agency. The results indicate that these tribal attributes are coupled with other standard location attributes, which negatively affects data quality for further analysis. The findings recommend that adding an independent subfield in the national standard crash classification for tribal elements and adding a specific tribal road type to the roadway data elements would be more effective for tribal crash reporting and analysis, which facilitates further safety analysis regarding all roadway types within tribal lands.
