'Carbin' App Uses Crowdsourcing to Measure Road Roughness

A new app called "Carbin” allows users to crowdsource road-quality data — particularly road roughness — with their smartphones. Using the accelerometers found in our everyday mobile devices, Carbin converts vehicle acceleration signals into standard measurements used by most Departments of Transportation. Carbin then collates the measurements onto , a publicly available global map.
