Abstract :
At present, the number and weight of vehicles play an important role in traffic planning, weighting, and road conditions assessment. This information is primarily obtained from fixed weight (weighbridge) or moving (WIM) stations, which are currently very expensive to install and protect. This research proposes a sensor-based and wireless-based approach, which is relatively inexpensive, and is used to measure the vibration of the pavement, to estimate the weight of moving vehicles. This system is implemented as a prototype in real highways, and the results of vehicle classification, weighing in motion, and its displacement estimate are compared with reference values. The accuracy of the system is higher than that of the Weighing Systems (WIM) standards and is better than the adjacent commercial WIM station that works with old technology. Because the sensors are directly in place, the system allows for real-time monitoring of road conditions.
