Road and Bridge Monitoring With Fiber-Optic Sensing

Fiber optic sensors have several inherent benefits that make them ideal for monitoring critical road and bridge infrastructure as well as traffic flow monitoring. Fiber-optic sensing converts existing fiber-optic cable into an array of intelligent sensors which deliver timely and accurate integrity data as well as traffic monitoring and incident detection information from the entire monitored route.

A fiber optic-based traffic monitoring system provides accurate and timely information across both urban and rural roadways. A system is capable of determining average traffic speed, detecting slow or stopped traffic, and estimating journey times between set locations. In addition, fiber optic sensors enable accurate and dependable health monitoring systems that can span all sizes of structures and capture both static and dynamic phenomenon. Luna Innovation's monitoring system instrumentation includes optical interrogators, long-range strain sensors, accelerometers, temperature sensors and tilt meters for crucial structural integrity measurements. This informative webinar will explain how the fiber optic system work and why it is inherently better for both long and short-term monitoring activities.

Key Takeaways

  • Roads and bridges can be monitored remotely using fiber optic cable
  • Data can be provided in real-time
  • Fiber can be used to monitor both new and existing roads and bridges
  • Structural deformities can be identified before a critical event occurs
