The client is large speed camera manufacturer. Because roads are getting busier, more cars will be driving at the same time along a speed camera. In order to determine whether a car drives too fast, the speed camera must be able to distinguish the different cars.
The current speed cameras work in a different way: they only signal that ‘something’ passes through 2 measuring points. On the basis of the elapsed time between the passing of these 2 points, a speed camera calculates that a car drives too fast and therefore it flashes. When several cars pass these points almost at the same time, the speed camera can’t make the distinction that it concerns different cars. Therefore, the question was: find a method by which speed cameras can distinguish cars and their speed on individual basis. So that cars which too fast can be flashed for a speeding ticket.
