Data imputation has been practiced by traffic engineers since traffic data programs were established in the 1930s. However, a literature review indicates that no research has been conducted to assess imputation accuracy. An examination indicates that current practices are varied and intuitive in nature. Typical methods used by highway agencies are thus statistically evaluated and compared. It is believed that study results would be useful for traffic engineers to re-examine their practices and implement more accurate imputations.
