Using the KIT Driving Simulator to Evaluate Road Surface Roughness

Toward better road profile maintenance, this research investigated the relation between International Roughness Index (IRI) and riding comfort and between IRI and sense of security. A driving simulator that reproduces the behavior of vehicles traveling on uneven road surfaces was used for subjective evaluation of the road profile by test subjects. As expected, as the roughness increased and the travel speed increased, the riding comfort and sense of security decreased. The results are consistent with previous studies, and show the effectiveness of the driving simulator in evaluating road profiles.
