RoadBump Free

Developer's DescriptionBy David GrimmerRoadBump measures road roughness and produces International Roughness Index IRIRoadBump Free 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 Free 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 Free produces estimated International Roughness Index (IRI) and a Present Serviceability Rating (PSR) graphs. An accelerometer graph shows individual bumps, dips and waves. RoadBump Free 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: After installing and using RoadBump Free, please consider purchasing RoadBump Pro. RoadBump Pro differs from RoadBump Free in that it provides the following capabilities:- 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 recordingRoadBump Pro 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- 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- 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 secondRoadBump Pro provides these additional capabilities:- 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- Export segment level IRI averages- Export merged data with position and speed interpolated every 1/100 secA detailed users guide is available from our website www.grimmersoftware.com/roadbump.htmlRecent changes:Fixed bug that would draw color coded map line when option was turned off and a marker was moved.Content rating: Low Maturity
