We outline an affordable system that continuously monitors the road network for surface damage like potholes and cracks. The system consists of a structured light sensor and a camera mounted on vehicles that travel the roads on a regular basis. It makes use of sensors and equipment already present on the vehicle, like GPS on transit buses. The data is collected from many vehicles, aggregated and analyzed at a central location and the assessment results are displayed interactively to facilitate road maintenance operations. We describe in detail the key sensor, the data it collects and the algorithm to detect cracks and potholes.
