A toll barrier system is a type of weighbridge accessory that is commonly used at toll plazas and other locations where vehicles are charged for access or use of a facility. The toll barrier system typically consists of a barrier gate that is activated based on the weight of the vehicle being weighed on the weighbridge. When a vehicle approaches the toll plaza or facility, the driver must present a payment method or access pass. The weighbridge system then determines the weight of the vehicle, and the toll barrier system is activated accordingly. If the vehicle is within the allowed weight limit, the barrier gate is lifted, and the vehicle is allowed to pass. If the vehicle is over the allowed weight limit, the barrier gate remains closed, and the driver is directed to a designated area for further processing. The toll barrier system can be automated and synchronized with the weighbridge system to ensure that vehicles are charged the correct amount based on their weight. This can help prevent revenue loss and improve the overall efficiency of toll operations. In addition to toll plazas, toll barrier systems can also be used in other applications, such as access control for restricted areas, parking facilities, and other facilities where vehicle access is controlled by weight.
