Weigh - in - motion (WIM)
The biggest wealth of every country lies in its transportation infrastructure so the protection of negative impacts on infrastructure must be provided. The progress of sensor technology proposes today several types of weigh-in-motion systems, which have been tested for their efficiency, accuracy and cost-effectiveness. Technologies of piezoelectric sensors, bending plates and load cells are used for a number of applications comprising weigh enforcement, traffic data collection, bridge and toll control systems and so on. Advantages of using WIM technology are various and its benefits affects all road users (transport companies, public, public transport authorities). Potential of WIM application has been recognized in the leading EU countries, so the existence of the numerous WIM projects.
