SafetyDistance is a solar powered road signs that line the outer edge of the highway. Their presence increases nighttime visibility and ensures road safety. The cylinders detect passing cars via infrared sensors and trigger off the warning lamp. Cars tailing the first are forewarned and can pace their distance accordingly. Depending upon the distance between the two cars, the lamp glows from red (too close) to yellow (close) to green (safe distance), and then ultimately switches off when no cars are around. The idea is to increase road safety via a self-sustainable design.
