Light signaling system has round diffusing disks replaced by red and flashing and illuminating green arrows for right and left travel and straight-on travel

摘要

The system has round diffusing disks replaced by red and flashing and illuminating green arrows for right and left travel and straight-on travel. A red arrow means stop and a flashing green arrow means it is possible to proceed if this will not hinder or endanger the flowing traffic or prepare to drive. An illuminated green arrow means you are free to proceed. An independent claim is also included for a crossing circuit.
