Crash Data Improvement Program Guide

The purpose of this Crash Data Improvement Program Guide (CDIP Guide) is to assist state crash database managers and other traffic safety professionals in identifying, defining and measuring the characteristics of the data quality within the state crash database. The quality characteristics consist of the timeliness, accuracy, completeness, consistency, integration and accessibility of the crash data. The CDIP Guide will assist States to establish baseline measures that reflect the current status of the quality characteristics and to conduct periodic updates to assess progress in improving crash data quality. The CDIP Guide uses examples of good practices to help illustrate the use of the quality measures. Most of the examples of good practices cited in the Guide are drawn from practices adopted by the states of Michigan, Iowa and Kentucky. All three states are among the leaders in developing, maintaining and managing crash databases that are capable of providing good quality crash data to users. Their ability to provide this quality data is in large part due to the constant vigilance with which they scrutinize the information (data) being provided to the database and the actions they take to maintain and improve the quality of their crash data.
