ABSTRACT
Crash reporting is a crucial component of roadway transportation safety analysis. In 2017, new crash report forms were introduced in Wisconsin. If or when law enforcement does not file a crash report, drivers are required to complete a self-reported crash form. The analysis in this paper consisted of quantifying the effect of intervention and accuracy of information. Significant changes in police crash reports were observed in most crash severities after intervention. Driver self-reported crashes showed slow adoption and limited information to accurately map crash locations. Driver self-reported crashes were inconsistent compared to conventional KABCO crash distributions. There was a significant difference in police reported and driver self-reported crashes by jurisdiction. Police reported crashes were predominant in populated urban areas and driver self-reported crashes were prevalent in rural areas. The results of this study provide valuable information for improvement in crash reporting.
