Road and Traffic (WIM)
 Road WIMRoad damage caused by overloaded trucks Heavy vehicles – and trucks in particular – impose a burden on the road infrastructure, as there is an exponential relationship between axle load and road damage. While the main factor affecting road repair and maintenance requirements is the number of trucks, trucks with axle loads higher than the legal limit cause a disproportionately high percentage of the damage to the infrastructure. Furthermore, overloading – whether of one or more axles or the whole vehicle – is also likely to have an adverse impact on traffic safety.
When it comes to monitoring road traffic loads, attention is now increasingly focused not only on gross vehicle weight but also on axle and wheel load. The authorities have an appropriate interest in detecting vehicles with excessive axle loads.

Rail WIMIn-line weighing systems
identify unsafe rail cars The need to monitor and control loading and weight of rail cars has increased since the train operators were separated from the companies owning and maintaining the railroads and also since railroad pricing and train access charges were introduced. For weighing vehicles, weighing bridges were widely used in the past. In order to improve efficiency, in-line wheel load weighing systems have been deployed. Additionally, such in-line weighing systems are now used by railroad companies to check the operational safety and, consequently, to identify potentially unsafe cars. These systems detect overloaded cars, uneven load conditions and wheel damages.
