The latter includes traffic signs and crash-barriers. The collected information as is, or automatically displayed and interpreted, provides a basis for the continuing monitoring and management of road surfaces and associated road-side constructions. The laboratory has been or is involved in the following developments. Automated detection and localization of road signs in films of the road and road-side . The latter are taken by cameras, continually during truck measurement operations.
Automation here lessens human interaction and allows for a faster processing of more data.
The lab has an ongoing project for sign recognition. The lab has produced a prototype GIS system for data fusion. The captured or computed heights are employed to characterize road roughness or rugosity. The lab helped define and refine road roughness computations. A few technical details follow.
