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.

    David Crawford investigates a promising development to counter the problem of fog in the Gulf States. Despite being a largely desert area with low rainfall, fog is a major driving hazard in countries on the Arabian peninsula, such as the UAE. The fog is the result of moist air moving across from the neighbouring Gulf during the afternoon and evening, and experiencing radiation cooling at night.

    The ‘value of time’ concept can be a vital decider in prioritising transport projects, as Lorenzo Casullo and Serbjeet Kohli of Steer Davies Gleave explain. How much do travellers value their time and how much would they be willing to pay for a better and faster transport option? For many years Steer Davies Gleave (SDG) has been collecting this type of information from thousands of people across the world as it researches travellers’ behaviour. And given the importance of this parameter for transport mo

    A combination of technologies is leading to major congestion and cost reductions during roadworks on the UK’s motorway network. Innovative construction programme scheduling technology and the deployment of moveable barriers has achieved substantial savings of money and time on UK motorway roadworks managed by the Highways Agency (HA). This combination has set the scene for a new generation of road usage analysis tools. The HA’s objective was to reduce the congestion caused by lane closures during roa
