Abstract
<p>This study aims to develop a numerical model to evaluate the road roughness condition using acceleration time histories recorded by car navigation systems. The acceleration record of transverse component of the vehicle is employed to detect the road sections with the international roughness index (IRI) of 12 mm/m or above. To achieve the objective, the IRI was measured with the interval of 10 m in Yokohama City and Chofu City. The relationship between the IRI and the accelerations recorded by car navigation system was evaluated, and logistic regression analyses were performed. The discrimination ability of the numerical model was revealed, and the model was applied to the acceleration time histories accumulated in March, 2015.</p>
