Crash data availability and best practices across the United States

Conclusions from our analysis include (1) the importance of linking crash data with other data sets (e.g., injury surveillance data); (2) the need for partnerships and collaborations between universities, advocates, and agencies; and (3) challenges with management of quality control. We present the results of our quantitative and qualitative work to offer best practices and Vision Zero guidance for state policymakers and traffic crash data experts.
