By preventing one pedestrian stream from appearing at right of way while the other
is at right of way, it allows the pedestrians time to cross one carriageway before the
other crossing is allowed to appear at right of way.
The firmware provides the facility for a dual stand-alone pedestrian stream
controller, which can be enabled using the handset command CIL.
Special conditioning must be used if other combinations are required, e.g. when
stream 0 is an intersection stream and streams 1 and 2 are the dual pedestrian
crossing near-by, or where more than two stand-alone pedestrian streams need to
be controlled.
