Abstract

A system for determining the difference between an existing road level and a required level road is disclosed. The system includes a device having a plurality of sensors in an array which extends vertically. The sensors detect the position of a level line. The device has means which transmit a signal indicative of which sensor is detecting the presence of the level line. The signal is picked up by an in-cab unit constituting another part of the system. This unit displays the signal as a variance between required road level and current road level.
