DRIMS (pronounced "Dorimuzu") is a road evaluation system capable of measuring crack ratio, rut depth, and IRI (International Roughness Index) using data acquired from smartphone sensors (accelerometer, angular velocity, GPS) and cameras.

It can be operated with a general passenger car, eliminating the need for conventional dedicated measurement vehicles. Its high flexibility in vehicle type and smartphone placement allows for advanced road surveys during routine patrols.

Furthermore, AI image analysis automatically detects road surface damage and visualizes the results on a map, contributing to the efficiency of inspection, recording, and evaluation operations, as well as the advancement of road maintenance.
