Grimmer Software Releases RoadBump
Grimmer Software has published RoadBump - an Android app that uses the accelerometer and GPS of a smart phone to measure the roughness of a road
Little Rock, AR, April 29, 2015 (Newswire.com) - RoadBump is a tool for road maintenance and engineering professionals to get estimated IRI information that previously was available only through very high cost laser profilers.
RoadBump uses your Android device's GPS and accelerometer to measure the roughness of a road. It displays a map of the road that was measured, and allows you to zoom in to measure any part of the traveled path. RoadBump produces estimated International Roughness Index (IRI) and a Present Serviceability Rating (PSR) graphs. An accelerometer graph shows individual bumps, dips and waves.
I think this is a great program!

RoadBump is extremely easy to use. Simply press the giant start button, drive the road what you want to measure at normal speeds and then press the giant stop button. Road data is gathered and held on the device so a network connection is not required.
RoadBump Highlights:
- Estimates International Roughness Index (IRI) in inches/mile or m/km
- Uses low cost Android phone or tablet
- Supplements high end (high $) analysis
- Covers long distances at normal varying speeds (up to 2 hours of recording)
- Provides actionable data to support decision making
- Extremely easy to use
- Tested at the National Center for Asphalt Technology (NCAT) at Auburn
- IRI values are normalized for speeds between 20 and 70 MPH
- Network connection not needed to record and review data
- Stores and manages recordings locally *
- Save a portion of a recording as a separate recording *
- Export data via email, Google Drive or Dropbox – all as CSV files *
- Graphs show data between the moveable start and end markers
- Graphs IRI as moving average or segment average steps
- Graphs Present Serviceability Rating (PSR) as a function of IRI
- Graphs speed and accelerometer data
- User defined segment length
- Export segment level IRI averages *
- Export merged data with position and speed interpolated every 1/100 sec *
- Supports US and Metric measurements
- Color coded path on map
- Configurable color limits for smooth, normal and rough
- Switch between street and satellite views of path driven
- Map can be zoomed, rotated and aligned to graphs
- Adjustment for vehicle / device variations
- Accelerometer data recorded 100 times / sec
- GPS data recorded every 1 second
