Measurement techniques for the road

Fraunhofer IPM develops optical measuring systems to measure the road environment and the road surface. High-resolution laser scanners combined with fast image processing provide measurement data on longitudinal and transverse evenness and crack density of the road surface. Based on this data, maintenance work can be planned specifically. Measurement data on the road environment, converted into 3D or 2.5D models, are used to model cities and their traffic flows or to plan infrastructure expansion. In many cases, Fraunhofer IPM offers software for automated data evaluation in addition to measurement technology.

Our systems record measurement data down to the submillimeter range at driving speeds of 80 kilometers per hour and more - precisely and reliably. Fraunhofer IPM measuring systems for road condition monitoring are in operation worldwide.


Longitudinal / Transverse Evenness


We provide the technology for a detailed three-dimensional height profile.


Structural Features


The Pavement Profile Scanner PPS plus records road surfaces at 80 km/h with millimeter accuracy using laser scanners and generates photorealistic images.


Road Environment


3D and image data enable construction planning from the desk. No site visits are required.


Tunnel Condition Monitoring


The multidimensional inspection determines not only the geometry and surface structure of tunnels but also possible water leaks.

Federal Highway Research Institute uses PPS-Plus

The Pavement Profile Scanner is part of the latest measuring vehicle MESAS of the Federal Highway Research Institute BASt. The research vehicle records the condition of road surfaces and the substance of the asphalt surface and thus provides the basis for optimum maintenance planning. After extensive test runs, regular operation now begins.
