About this app

RoadBump is a tool for road maintenance and engineering professionals to get estimated International Roughness Index (IRI) information that previously was available only through very high cost laser/inertial profilers. RoadBump provides objective data on all types of roads (asphalt, concrete, dirt, gravel…)

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 IRI graphs as a moving average or in segment lengths that you specify (such as .1 mile or km). An accelerometer graph shows individual bumps, dips and waves.

RoadBump Pro 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.

NOTE: Before purchasing the professional version of RoadBump (RoadBump Pro), please install and run the RoadBump Free app to ensure that the application records and displays recordings on your device.

RoadBump Pro differs from RoadBump Free in that it provides the following capabilities:
- Extract data that can be imported into ESRI’s ArcGIS GIS product
- Ability to save and manage recordings on your device
- Ability to move data to a PC via email, Google drive or Dropbox
- Ability to save a portion of a recording as a separate recording

RoadBump Pro Highlights:
- Estimates International Roughness Index (IRI) in inches/mile or m/km
- Graphs IRI as moving average or segment average steps
- Uses low cost Android phone or tablet
- Supplements high end (high $) analysis
- Extract data that can be imported into ESRI’s ArcGIS GIS product *
- 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 varying speeds
- 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 spreadsheet CSV files *
- Graphs show data between the moveable start and end markers
- 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 shows smooth, normal and rough
- Configurable color limits for color coded path on map
- 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
* RoadBump Pro only
