Which of the following most accurately describes the problem?

• A vehicle body called Clear Cone is designed to reduce the need to cone off traffic lanes for survey work. It has just completed successful trials with the Transport and Road Research Laboratory.

The Clear Cone body features a rotating turret equipped with infra-red devices to survey up to three lanes from the hard shoulder.

The data collected is converted into a three-dimensional map of the road surface, which the makers claim is accurate to within 3inm.

Clear Cone could reduce congestion by eliminating the need to cone off up to 200km of road every year for surveys.
