About the research
The main objective of this study is to determine the feasibility and benefits of using the automated distress data (roughness, rutting, and individual cracking measurements) in the HWYNEEDS program to replace the existing manually collected pavement condition ratings. The study will also investigate the impact of using the automated distress data on the overall needs and determine the sensitivity of the HWYNEEDS program to the use of the automated distress data.
