Non-invasive road sensors in Road Weather Information Systems (RWIS) and AVL Systems
This project will implement non-invasive road temperature and road condition sensors on three Road Weather Information Systems (RWIS) located in Minnesota (D1 Mitchell Bridge, Metro - Cayuga Street Bridge, Inver Grove Heights). Current passive road sensors are embedded in the road surface. Whenever there is a construction or maintenance project that impacts the road surface (mill and overlay, seal-coating, patching, etc.), the embedded sensor must be replaced. This, and periodic RWIS site and sensor maintenance, requires lane closures and cutting the road surface to install the sensor and cables. The non-invasive sensors will be attached to the RWIS tower or a pole near the roadway and use laser technology to read the road surface temperature and condition (water, ice, slush, and snow); subsequently, future road projects do not impact the sensor and periodic maintenance does not require lane closures.
