Making sense of it all with NEC

Vehicle-type and traffic-volume data collection in real-time and predictive congestion planning for road agencies just got easier with new optical fiber sensing technology from NEC.

Visit the company stand to get a glimpse of how it works and discover how - for the first time in the world, says NEC - its new optical fiber sensing technology enables sensing from already-laid optical fibers for communication. By simply placing an optical fiber sensor device at one end of the optical fibers, the system can sense vibrations, temperature and sounds within a range of up to 100km at a resolution of about 50cm.

Unlike conventional technologies, laying new optical fibers for sensing purposes is not required. This means that the huge amount of optical fiber-based communication networks running throughout the globe can be used as sensors.

Optical fiber sensing technology can easily monitoring a wide area and does not demand new power sources, explains Yoshiyuki Yajima, a member of the applied sensing research group at NEC. This advantage is further enhanced by the flexible and light characteristics of optical fiber cables. Also on the stand is a demonstration of new object identification technology to help drivers avoid collision with objects, from people along the highway and animals on the road or about to jump into incoming traffic to wrong-way drivers. NEC’s road infrastructure enhances safety and efficiency by monitoring environments around intersections and highways, working with vehicles through wireless networks, advanced sensing and AI-based object recognition.
