abstract="A high-speed road monitoring system has been developed at the Transport and Road Research Laboratory. It consists of four laser sensors mounted on a 4.5 m-long beam that is supported by a two-wheeled trailer towed behind a small van. Measurements are made by the configuration of laser sensors under the control of a computer system located in the vehicle behind which the trailer is towed. Longitudinal profile, wheel-track rutting, and surface macrotexture are measured as the system travels over the road networks in the normal traffic stream; provision is being made for the measurement of road crossfall, gradient, and horizontal curvature. The principles of system operation in the different measurement modes are described and illustrated. Use of the measurements made by the high-speed system in studies of the effects of unevenness on the road user and in detecting structural deterioration of roads is described. Its potential for use in making surveys of the road network at a relatively low cost, locating areas of distress, and guiding the deployment of other, more specialized equipment is discussed within the context of the development of a cost-effective maintenance management system.<p /><p>Language: en</p>",
