Lane
Use Signals
Excel Technology Group has developed Lane Use Lamp Controllers which provide
safe signal display for the operation of lane use signals utilised where
vehicle traffic direction is changed, that is, contraflow, tidal flow and
reversible lane systems. The LULC card incorporates a firmware conflict
monitor that immediately disables display operation if a ‘back-to-back’
green to green signal display state is detected. For added protection a
failsafe relay circuit module may be added, which provides a green supply
signal ON state only when the opposing red is active. The LULC controllers
may be interfaced to wire or wireless communication mediums for maximum
flexibility. |
