Road Degradation Extraction Method Using Car Probe Data

Abstract

In a previous study, we proposed a method of extracting road deterioration points using car probe data. In this paper, we collected car probe data and applied the proposed method with Fujisawa City as the target area. From the analysis results, road degradation points were extracted. Prior to detailed road deterioration diagnosis using MMS, we carried out a field survey by visual inspection. As a result, road deterioration was found at the extracted location. It was shown that the proposed method is useful, therefore, we promote refinement of the method.
