BumpRecorder app evaluated road roughness

BumpRecorder of Japan will be at the 2015 ITS World Congress with an innovative system that can evaluate road roughness, using only a smartphone. A user simply drives a passenger car with BumpRecorder installed on a smartphone and it will record vehicle vibration without the need for any special equipment. Recorded data is uploaded to the BumpRecorder Web server — road roughness to level 2 IRI (International Roughness Index) and original bump index will calculate in 5–10 minutes, and it will be displayed on

BumpRecorder of Japan will be at the 2015 ITS World Congress with an innovative system that can evaluate road roughness, using only a smartphone. A user simply drives a passenger car with BumpRecorder installed on a smartphone and it will record vehicle vibration without the need for any special equipment. Recorded data is uploaded to the BumpRecorder Web server — road roughness to level 2 IRI (International Roughness Index) and original bump index will calculate in 5–10 minutes, and it will be displayed on mapping on the web map window.

The company states that BumpRecorder does not require calibration driving before actual roughness measurement driving gets underway.

This is because vehicle vibration specification is analysed automatically using recorded acceleration data. The company claims that the class 2 IRI values provided by the system are stable, even if vehicle type and driving speeds are different.

The BumpRecorder App for Android smartphone is free to download from Google Play. There is a data analysing fee which is a fixed amount for a management area and within that area, measurement distance is unlimited.

    The growing popularity of hybrids and electric vehicles gives rise to new safety issues in urban environments, as many of the aural cues associated with engine noise can be missing. The solution is to intelligently make vehicles noisier. The rise in popularity of hybrids and Electric Vehicles (EVs) is a result of environmental pressures, shifts in taxation and emerging technologies for batteries and motors. Competition among the car manufacturers means these vehicles need to be cost effective to buy and ope

    Q-Free’s Andrew Lees looks at regional characteristics and technology trends in the global Weigh-In-Motion market. The principles of Weigh-In-Motion (WIM) are well established. Data derived from vehicles passing over in-ground sensors can be interpreted for vehicle classification (axle counts and spacing) and positive identification (especially when linked to image capture) applications as well as to derive individual axle and gross vehicle weight (GVW).
