Weigh In Motion

from Wikipedia, the free encyclopedia

Weigh In Motion (= weigh in hover) serves to detect the vehicle axle while the vehicle drives over it.

With WIM, the total weight , axle loads , axle spacing , vehicle category , speed , vehicle length and time gaps can be recorded and statistically evaluated for each individual vehicle .

Possible uses

The results are used to dimension roads and engineering structures, maintenance planning, security, economy, transport studies, research (e.g. engineering structures) and other traffic-related purposes. In addition, the systems are also used by the police for pre-selection during heavy traffic controls.

Other possible uses are the access control on bridge structures that have a vehicle weight class limitation. For example, the WIM system was used on the Schierstein Bridge between April and November 2015 , as only vehicles up to 3.5 tons were allowed to pass the bridge and heavier vehicles were prevented from continuing by means of a traffic light and barrier system.
