The acquisition of new technology on the automatic road analyzer (ARAN) vehicles for sensing pavement conditions requires that a statistical analysis be performed to make the data collected using the new three dimensional (3-D) Sensing equipment compatible with the older data collected with the strobe systems. The objectives of the project are to: (1) identify differences in cracking, roughness, and rutting outputs between existing two dimensional (2-D) and new 3-D pavement imaging systems; (2) analyze the impact of new data-rich technology on the reported cracking, rutting, and roughness; and (3) develop transfer functions/correction factors to ensure comparability of historical and newly-collected data. |
