The road networks often cannot cope with the increased traffic load; moreover, the roads in bad condition reduce the overall capacity of a network. Pavement condition is a central aspect of road transportation infrastructure management, and is particularly highlighted in Hungary; the loss in travel time, the damage in vehicles results in significant indignation in society and gives an everyday topic for the actual political life. Scheduling road construction works requires effective monitoring of road conditions and the various components of a particular network have to be classified by quality. This paper introduces a complex road pavement measurement system designed primarily for pothole and crack detection. The system, installed in a vehicle is composed of a navigation unit, image acquisition module and a photogrammetric image-processing subsystem. The navigation unit consists of an integrated GPS/INS system; the trajectory and attitude of the vehicle at the required accuracy is provided by a Kalman filter. All the sensors and a high-speed computer are mounted on a pick-up. The low-end inertial measurement units (IMUs) have continued to improve in the last years, which broadened their application fields. The paper discusses the experimental results of the IMUs. First we compared the performance of two low-end IMUs on various road surfaces (wavy pavement, potholes etc.); secondly we analyzed their impact on the application. The obtained results have proved the potential of these types of sensors for this kind of road engineering applications.
