If this sequence is required, the pedestrian phase has to be programmed as a traffic

phase in order to obtain the amber signal. If a wait indicator is required, this has to be

programmed as a switched sign phase (see section 3.2.5(b)).

Green must always be used for “at right-of-way” for traffic, pedestrian & green arrow

phases because of the green conflict facility.

14.2 ALTERNATIVE START-UP SEQUENCES

As an alternative to the standard start-up sequence and blackout during Part-time

mode, the following may easily be provided as stated in above statement.

(a) Start-up Sequence

FLASHING AMBER for 6 seconds

ALL-RED for the length of the starting intergreen plus the amber leaving time.

With ROW going first to Stage 1 before completing one cycle.

(b) Part-Time Mode

At the changeover to Part-time mode, following the expiry of all phase

minimum greens, ROW goes to an all-red stage (normally Stage 0) for a

specified time. This is then followed by flashing amber to all traffic phases and

blackout to all pedestrian and green arrow phases.

The specified time in the all-red stage is provided by allocating a dummy phase

to the stage. The minimum green value of the dummy phase will provide the

time.

At the changeover from Part-time mode the start-up sequence is effective.

The signal sequence during all other modes remains the same as the standard

sequence unless requested to be changed.
