In last decade, the overloaded trucks increase in countries with weak infrastructure, for examples in Indonesia the percentage of overloaded trucks is more than 60% [1]. To prevent this violation of the country regulations was developed weigh-in-motion (WIM) network stations. For France and not only, the network of WIM stations improved traffic safety, fair competition between transportation companies and infrastructure lifetime [2]. The WIM station is able to determine: the type of the vehicle, the gross weight of the vehicle, the load on each axle, vehicle’s speed and so on. The most common sensors used for obtain data information are strain gauges force sensors and piezoelectric sensors. In this paper will be analyzed the main advantages and disadvantages of each type of sensors used for WIM stations.
