Bridge weigh-in-motion (BWIM) is a technique of estimating vehicle loads on bridges and can be used to assess a bridge's structural fatigue and therefore its life. BWIM can be realized by analyzing the bridge deflection in terms of its response to moving axle loads. To obtain accurate load estimates, current BWIM systems require strain sensors, whose (re-) installation costs have limited their application. In this paper, we propose a new BWIM approach based on a deep neural network using accelerometers, which are easier to install than strain sensors, thus helping the advancement of low-cost BWIM systems. By learning the bridge dynamism, our model estimates axle loads successfully from the noisy acceleration signals sampled on a real bridge in service.

“…Several research works have proposed MAC protocols for multi-priority sensor networks [2,22,23,25,31] and analyzed the effectiveness of CSMA -persistent scheme in terms of network delay and reliability [27][28][29]. In particular, Bhandari and Wang [2] proposed a priority-based deterministic channel access mechanism to reduce the access delay by assigning different MAC layer attributes and used an emergency indication slot to prioritize critical traffic over normal traffic. Although the research enhanced the reliability of the sensor networks, it only considered two levels of priority.…”

“…NDUSTRIAL wireless sensor network (IWSN) can be defined as a network of sensors which gathers information from monitored areas using wireless links. The ease of deployment and the potential for scalability/flexibility of IWSNs have resulted in its wider adaptation [1][2][3][4] such as automation, process control, health industry and environmental monitoring [5][6][7][8][9].…”
