Virtual Speed Bump / Driving assistance

Virtual Speed Bump
Virtual Speed Bump

Virtual Speed Bump aims to mention drivers when they over speed. These tiny devices could be installed uniformly along the both sides of a freeway. It could calculates the speed of a car by the formula (V=S/T). The distance between two tiny devices is 5 meters. The time of a car passing by contiguous devices will be regarded as T in that formula. Then, the speed of a car could be worked out easily. Meanwhile, if a car over speed, each four devices would work together to cast a cautionary pattern.
