At the Purdue SMART Lab, our team is also testing novel sensors that monitor transportation infrastructure by embedding them in several Indiana interstate highways. We plan to expand to other state highway systems in the next few years with a goal to better accommodate increased traffic and provide accurate estimates of road conditions during construction and its life.

Sensors embedded in concrete pavement acquire information about the infrastructure’s health condition in real time and communicate the data to computers. Electrical signals are applied through the sensors. Concrete’s vibrations are converted into electrical signals that are read and analyzed by lab-built customized software. This enables transportation engineers to make effective and data-driven decisions from opening roads to traffic and to proactively identifying issues that cause damage or deterioration.
