About this app
R4 is a simple, portable and repeatable system to collect real-time roughness.
The Roughometer 4 continues a tradition established over twenty years. It provides a simple, portable and highly repeatable measurement of road roughness (International Roughness Index, Bump Integrator or NAASRA counts) on sealed and unsealed roads. The Roughometer 4 is a World Bank Class 3 response type device, that measures IRI directly from the axle movement using a precision accelerometer. This eliminates uncertainties associated with the vehicle, such as the vehicle’s suspension or passenger weight. The unit utilises a wireless distance sensor and can be operated with most Android phones or tablets. The software displays collected surveys on a Google Maps interface and allows for MP3 voice recording of events.
Survey data is stored on the Android device, with the amount of collected data only limited by the storage capacity of that device.
The unit is operated using two wireless buttons mounted on the vehicle dashboard or steering wheel.
Features of the Roughometer 4 include:
Accurate and repeatable outputs regardless of vehicle type, suspension and passenger loads
Two-button wireless operation
Wireless distance sensor, with option to use external Distance Measurement Instrument (DMI)
Axle-mounted inertial sensor used to determine road profile and roughness
Utilises GPS functionality on Android device
Outputs in International Roughness Index (IRI), Bump Integrator or NAASRA counts
Supports projects and pre-defined survey routes in KML format
Multi-format reports available including KML and CSV files
