iDRIMS measurement

iDRIMS measurement is an app to measure acceleration, angular velocity, GPS and others for road roughness condition evaluation. iPhone/iPod touch is installed in a vehicle to measure its dynamic responses. Based on the data, International Roughness Index (IRI) can be estimated*. The app, capable of synchronously obtain acceleration, angular velocity, GPS information, magnetism, movie, photo, and sound, can also be used for general-purpose measurements other than road condition evaluation.
*For IRI estimation based on iDRIMS measurement data, contract with JIP Techno Science is required.
