Long-Term Pavement Performance Compliance With Department of Transportation Information Dissemination Quality Guidelines


This document demonstrates the LTPP program's focus on data quality in relationship to the DOT IDQG issued more than 10 years after the start of the LTPP program. While the LTPP program is proud of its record on data quality issues, this quality focus also results in identification of improvement opportunities. Implementation of these improvements is highly dependent upon program funding.

The improvement opportunities are organized and presented using the main topic areas contained in the DOT IDQG.
