Bridge protection

Efficient monitoring protects bridges against overloading and prevents accidents

Bridges are sensitive components of the traffic infrastructure, and their lifetimes are limited. Traffic volumes are soaring all over the world, and many bridge structures are in the process of aging – two factors that combine to create a hazardous situation. Weigh In Motion systems from Kistler are the solution of first choice for both bridge monitoring and bridge protection: they supply reliable data about the actual loads on bridges to schedule maintenance accurately or alternatively WIM can detect overloaded vehicles before passing the bridge and restrict access. By opting for the complete, cost-effective KiTraffic Statistics package, users can quickly implement all the advantages of Weigh In Motion – and our new Lineas Compact sensors, installed under the road surface, ensure maximum service lifetimes.
