Road condition monitoring plays a key role in ensuring safety and comfort to various road users, from pedestrians to drivers. Having information on infrastructure quality guarantees road managers an adequate maintenance on time. While professional road profilers equipment based laser scanners, image, and video cameras exist, they are usually associated with high purchase, operation, or maintenance costs that not always fit the budget from a small city or village. We believe that road users can contribute to monitor the pavement quality simply by using their own smartphone while driving. The Bumpy Road projects tries therefore to develop a collaborative application where data collected with the help of the drivers can be aggregated and analyzed, allowing a fast and low-cost surveillance on the roads conditions.
