Rusdorogi is a Google Map that shows at a glance the quality of Russian roads.
Good quality roads are displayed on the map in green. Satisfactory sections of road are marked in yellow, unsatisfactory roads are marked in red, and the really bad sections are displayed in dark red.
The data for the map is crowd-sourced and is collected by the users of a clever Android application. The app senses the vibrations on the user's phone. It uses a specially developed method of data processing which assesses the types of vibration on the phone and distinguishes between data coming from the car and other, normal background, vibrations.
