14.3 FLASHING SIGNALS

The signals on traffic, pedestrian and green arrow phases are normally a continuous

display. If required, the display may be programmed to flash instead. Either the type of

phases, i.e. traffic, pedestrian or green arrow, or individual phases may have a flashing

display on one or more signals.

e.g. traffic phases:

at no ROW: RED

changing to ROW: RED/AMBER

at ROW: GREEN

changing to no ROW: FLASHING AMBER

pedestrian phases:

at no ROW: RED

at ROW: FLASHING GREEN

traffic phases: Phases A,B & C Phase D

at no ROW: RED RED

changing to ROW: RED/AMBER RED/AMBER

at ROW: GREEN FLASHING GREEN

changing to no ROW: AMBER AMBER

The displays that are programmed to flash will do so every time they appear. They

cannot be programmed to be solid and flashing.

The flashing facility may also be applied to the start-up sequence and Part-time mode if

required:

e.g. Phases A,B & C Phase D

FLASHING AMBER FLASHING RED

RED RED

Followed by ROW going to Stage 1 before commencing a complete cycle.

14.3.1 Variable Flashing Signals

The facility is available to have flashing traffic, pedestrian and LRT signals. The rate of

flashing is adjustable with adjustable on/off ratio. The adjustment will be in 20mS steps

for both on and off periods, with a limit of 5.1 seconds.

Due to the operation of the green monitoring system, a period of less than 240mS for

the on or off time should not be used.
