Vehicle Mounted IRI Measurement System
IRIMETER-2 vehicle-mounted road roughness measuring device measures the International Roughness Index (IRI) of different road surfaces.
This vehicle mounted profilometers includes a control unit with graphic LCD display, one or two wireless inertial sensors and a roof magnet-mounted GPS antenna. The inertial sensors are mounted to MacPherson type front suspension of the vehicle. The sensors are wirelessly connected to the rest of the system.
IRIMETER-2 can be used on paved or unpaved roads. Wet, snowy or dusty road surface do not influence the accuracy of measurement.
All measured data together with measurement location is stored and can be downloaded to a computer via USB connection and can be viewed as graphs, tables and maps. Software is provided for easy processing and display of the data.
