A method and system for weighing vehicles in motion includes a base for anchoring to a roadbed; a weighing platform mounted on the base and adapted to receive wheels of moving vehicles along a longitudinal axis of the platform; at least one load cell disposed between the base and the platform adapted to provide load signals indicating loads applied by the wheels on the platform. A longitudinal differentiation mechanism, mechanically associated with the platform and the base, is used in measuring longitudinal forces. The longitudinal differentiation mechanism includes a mechanical unit adapted to provide a measurable resistance to a relative horizontal movement between the base and platform in order to differentiate horizontal forces produced by the wheels acting on the platform. A processing unit uses the load cell data and horizontal force data to determine the weight of the vehicle in motion. |
