| Abstract | Natura l disasters are becoming more frequent and more destructive. In particular,there are difficulties associated with near-real time or frequent pavement monitoring, because it is time consuming and costly.This study aimed to determine the relationship between the backscattering data of ALOS/PALSAR and international roughness index (IRI) data and to propose the new method (model) for the evaluation of highway riding quality, which could be used to monitor pavement conditions. The model was applied to investigate the influence of factors of the backscattering values of Phase Array type L-band Synthetic Aperture Radar (PALSAR). As the two set of training data used in the development process, the actual international roughness index (IRI) values along a highway in Ayutthaya province, Thailand were used. The analysis showed that an increase in the backscattering value in the HH polarization or the VV polarization indicated the poor condition of the pavement surface and among them the HH polarization is more suitable for developing riding quality evaluation. Final the two binary logit models developed were applied to analyze highway number 3467, to demonstrate the capability of the model. It was found that the highest assessment accuracy of the prediction of the highway level of service was 95.00%. |
