Performance of a Sensitivity Analysis on the Multi-Function Network Survey Vehicle (MFNSV)

Multi-Function Network Survey Vehicle (MFNSV) provides cutting-edge technology for obtaining highway pavement information such as; roughness, rutting, geometric data, road condition data as images and accurate distance measurements. The Hawkeye processing toolkit is used to process the data collected through a moving vehicle. The MFNSV manufacturer claims that the information is fairly accurate when the vehicle is driven within a speed range of 20 to 110 km/h.

Road pavement information was collected manually through accurate field measurements along 4 sample stretches on the A004 road, and the same information was collected through the MFNSV. The results obtained from the two methods were compared by carrying-out a sensitivity analysis test. The results of the sensitivity analysis showed that the information collected from all 4 sample test sites did not possess significant statistical differences between the data collected by the two methods.
