Abstract

 This paper applies the exploratory spatial data analysis method to grasp the spatial autocorrelation which is seen in the crack rate, rutting amount, IRI for the highway in Shikoku region. We find the hotspot locations and their properties that are more susceptible to degradation than other road sections. We also quantitatively evaluated factors which are influencing the degradation rate of crack rate using generalized linear mixed-effect model. As a result, we find that the structural conditions such as banking and cut soil have a significant influence on the deterioration rate of the crack rate in hot spots.
