The Crash Data Improvement Program (CDIP) was developed to provide States with a means to assess and measure thedata quality of their crash databases. As part of the overall CDIP program, NHTSA developed a revised CDIP Guide. The CDIP Guide provides an overview of crash data quality and guidance on how to measure and improve quality in terms of the six data quality characteristics - timeliness, accuracy, completeness, uniformity, integration, and accessibility. It also provides guidance for States on how to map their State’s police crash reports to the Model Minimum Uniform Crash Criteria. The CDIP guide is intended for State crash database administrators and managers, State Traffic Records Coordinating Committee members, State highway safety offices and State DOT safety office personnel, local traffic safety personnel (e.g., law enforcement, traffic engineers, city and county planners), and other Federal, State, and local traffic safety professionals.
