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.

    Road crashes are not as random as they may appear and analysing data can reveal patterns that can help various authorities target their resources more accurately. David Crawford reports. Figures from the US National Highway Traffic Safety Administration (NHTSA) show that in 2013 there were 32,719 people killed on American roads and 2.31 million injured. While these form part of an overall 25% drop over the decade from 2004, US Transportation Secretary Anthony Foxx continues to stress that reaching the procl
