Abstract:

This Innovations Deserving Exploratory Analysis (IDEA) project incorporates a new optical fiber design in a weigh-in-motion (WIM) system and tests its performance under simulated highway conditions. The fiber design consists of a dual core system using two light-guiding regions of different effective optical path lengths. A prototype fiber-optic WIM system was designed, fabricated and tested under both static loading and an actual vehicle. The static loading tests showed good correlation between load and changes in optical signal. The location of the load was also determined fairly accurately. Changes in optical signal under vehicle testing were similar to those under static loading. The system was further improved with attention to the optical set-up, data gathering capability and fiber optic configuration. The results show a good potential of the WIM system for determining the magnitude and location of vehicle loads. Additional refinements and prototype tests are needed before the technology will be ready for field implementation.
