The new system being tested on the A6 highway, near Madrid
At the heart of the system is a modified infrared multispectral image camera, equipped with an internal wheel of lens filters
According to scientists at Spain's Universidad Carlos III de Madrid (UC3M), approximately five percent of vehicles on the road are responsible for about 90 percent of toxic vehicle emissions. Short of pulling each and every car over to analyze its tailpipe output, though, how does one go about identifying the offenders? Well, the UC3M researchers have helped design a system that images the emissions of individual vehicles in real time, on highways up to three lanes wide.
