The table right is an example of a selection of road signs which could be achievable with such a lane controller.
Features and benefits
• Full matrix of yellow
• Red cross and a green arrow incorporated
• Typical dimensions
from 280mm x 330mm (11” x 13”)
to 580mm
x 680mm (23" x 28") display area
• Post or gantry mounted
Lane Control Signals are predominately used on continental Europe where individual lanes of traffic are controlled, as opposed to a larger sign controlling all the motorway lanes.
The upper part of the sign is fully populated with a two-colour fully programmable matrix system, The lower part of the sign is fully populated with yellow LEDs which show the distance to the hazard, as well as having a part populated green section that can display a green arrow.
Features and benefits
• Available in
standard size format
- upper display of 1280mm by 1280mm
- lower display of 1280mm x 320mm
• Fully programmable two colour LED matrix
• 20mm pitch between pixels
• Choice of LED colours available
• Conforms to the European specification EN 12966
• Interfaces to all software protocols
