A barrier helps control and regulate traffic flow in restricted-access areas, level crossings, etc.
By controlling entry and exit, an automatic barrier ensures smooth passage and provides greater overall traffic safety by preventing intruders from entering. These automatic control systems promote a peaceful and serene existence for the community within the controlled perimeter.
At each entrance, a photocell pointed at the door, triggers the passage bar which is positioned on the greeting corner (Angolo del saluto, 2006).
