2009 - NZ - Comparison of LTPP and High Speed Data

This research is to investigate the correlation of LTPP calibration data and NZTA High Speed Profile network survey data (through benchmark data). The objectives of the study are to:

• establish a process to link and report LTPP calibration data and benchmark data comparisons
• find out whether it is possible to compare LTPP calibration and benchmark data in a meaningful manner
• develop a framework for automatic tools for linking and reporting LTPP and high speed data.

The report found high correlations for roughness, medium for rutting and moderate for texture measurements. Very useful, particularly with regard to calibration and validation of profilometer measurements.
