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.

    New trials show Bluetooth and Wi-Fi signals can be reliably used for measuring travel times and at a lower cost than an ANPR system, but which is the better proposition depends on many factors. Measuring travel times has traditionally relied automatic number plate (or licence plate) recognition (ANPR/ALPR) cameras capturing the progress of vehicles travelling along a pre-defined route. Such systems also have the benefit of being able to count passing traffic and have become a vital tool in dealing with c

Fuel tax - the lifeblood relied on for 80 years to maintain and improve roads and transit systems - is now in considerable jeopardy in the United States. Increased vehicle fuel efficiency and a poor economy already hamper generation of fuel tax revenue; now a recent federal

    Purpose-designed travel information apps are emerging to support the real estate market in the US – and potentially more widely – in a major diversification away from the conventional automotive and navigation device sectors. In July 2013, Washington State-based Imprev, which develops web-based marketing support aids for realtors, announced its App Generator. Claimed as an industry first, this enables property businesses to create their own branded mobile apps to give away as marketing tools to potential
