Development of Low-Cost Weigh‑In‑Motion (WIM) and Response Spectra Techniques Phase I of “Development of a Cost-Effective Sensing System for Integrated Traffic and Pavement Response Monitoring in Support of Pavement Management"

The research team proposes to develop a long‑life weigh-in-motion (WIM) system with much lower costs using the piezoelectric sensors developed in a former EAR (Exploratory Advanced Research) project, as explained in the previous section. The team will name this system as P-WIM. The P-WIM will essentially consist of several piezoelectric disks sealed in a protective package made from engineering plastics. A wireless transmission module will be included in the package of the P-WIM to enable wireless data transmission. The P-WIM will be powered by solar panels and supplemented by the energy harvested from pavement deformations and vibrations. If the system is successfully developed, in the planned Phase II, the load response spectrums will be developed for evaluating the pavement responses. This additional capability will be integrated into a comprehensive system to supply asset management systems with unique traffic and pavement response data for better decision-making.
