Expert: Roads need to be 'smart.' Here's why.

Constant construction on your vacation route, jarring potholes during the winter and bridge collapses will continue until roads are "smart enough" to better prevent their own damage, says a Purdue University civil engineer.

Sensor

A sensor is a device that measures a physical quantity and converts it into a signal which can be read by an observer or by an instrument. For example, a mercury thermometer converts the measured temperature into expansion and contraction of a liquid which can be read on a calibrated glass tube. A thermocouple converts temperature to an output voltage which can be read by a voltmeter. For accuracy, all sensors need to be calibrated against known standards.
