Abstract: | The paper presents the main types of WIM systems, i.e. the ones already on the market, like the piezoelectric or with strain gauges systems, the optical fiber systems, existing now as prototypes and the hydraulic systems, currently on the drawing-board. Data provided by the WIM systems are very important for transporters that use the maximum road infrastructure. The continuity of the transportation between European countries and a fair-play competition demands have imposed extra accuracy on the vehicles weight control. |
