Abstract
We push forward examination about the effective road surface property investigation technique that utilized MMS (Mobile Mapping System). We made improved model MMS equipped with a high-density laser scanner and made a figure of contour from the three-dimensional point group data which we acquired in improved model MMS in yard road. And we confirmed the irregularity of the road surface in a figure of contour. In addition, we suggested a new evaluation index. By the main subject, we report an examination result of the road surface evaluation technique using three-dimensional point group data for true ways. Furthermore, we report an inspection result about the grasp possibility of the minute transformation of the road surface after the service of about a half year.
