Machine for milling traffic areas

A machine for milling traffic areas, the machine comprising:

• a vertically adjustable chassis carrying a steerable traveling mechanism and a drive unit for moving the machine and for driving a milling mechanism coupled to the drive unit;
• at least one laser scanner disposed on a side of the chassis for measuring the height relative to the surface of a traffic area to be milled;
• wherein the chassis is adjustable vertically in accordance with the measured values relative to the surface of the traffic area to be milled;
• and
• wherein the laser scanner is attached in a center side-wall region of the chassis, the laser scanner having a scanning plane disposed substantially parallel to the side-wall region of the chassis and at a height adapted for monitoring of a hazard region extending at least over a side length of the machine and producing a trigger signal if a disturbance occurs in the scanning plane.
