GENERAL OPERATION
1.
If in AØ, clear demands for FØ.
2.
DØ has a ‘0’ second all red to allow EØ (Tram Ø)
to start up as early as possible to reduce the chance of right turning
vehicles entering the right turn lane on the east approach (McIvor Highway).
SIGNAL GROUP OPERATION

Timesetting No. 1.
2.
XSF5 is used to set the special maximum extension
green time for SG5 in FØ.This time is
stored in Special Purpose Timesetting No. 13.SG5 is forced off after this special maximum extension green time.
Signal Group 6

green time for SG6 in FØ.This time is
stored in Special Purpose Timesetting No. 14.SG6 is forced off after this special maximum extension green time.
Signal Group 7
1.
SG7 operates white-yellow-red in EØ.
2.
SG7 is red through FØ, AØ, BØ, CØ and DØ.
3.
When XSF7 is set, SG7 red is switched off at the
start of AØ.
4.
When XSF7 is set, SG7 goes red with SG1 in AØ and
remains red through BØ, CØ, DØ and FØ.
Signal Group 8 – General Operation
1.
SG8 operates as a 3-aspect partially controlled
right turn (conditional red) between 08:00 and 09:15 and between 15:00 and
18:00 Monday – Friday.
2.
SG8 operates as a fully controlled right turn at
all other times.
3.
SG8 is controlled by Special Movement Timesetting
No. 3 within BØ.
BØ all
red timesetting is substituted for Special Movement Timesetting No. 3.
4.
XSF8 is used to set the special maximum extension
green time for SG8 in BØ.This time is
stored in Special Purpose Timesetting No. 15.SG8 is forced off after this special maximum extension green time.
5.
The operation of SG8 is controlled via the
internal clock (on-line and off-line).
Signal Group 8 – Fully Controlled Right Turn
1.
SG8 fully controlled right turn starts when SG8
is red in DØ, EØ, FØ, AØ, B3Ø and CØ late start after 09:15 and after 18:00
Monday – Friday.
2.
During the fully controlled right turn operation:
a.
Detector 11 places locking calls for BØ and
extends BØ.
b.
Ignore calls and extension for CØ placed by
detector 11.
c.
Expire CØ ECO.
d.
If in CØ, ignore demands for BØ (SG8) from
detector 11.
Signal Group 8 – Partially Controlled Right Turn (Conditional Red)
1.
SG8 partially controlled right turn (conditional
red) operation begins after CØ late start after 08:00 and after 15:00 Monday
– Friday.
2.
During the partially controlled right turn
(conditional red) operation:
a.
SG8 operates green-yellow-red in BØ.
b.
SG8 goes red with SG3 in CØ and remains red
through DØ, EØ, FØ, AØ and B3Ø.
c.
SG8 closes down at the end of BØ green, remains
red through CØ late start, then goes ‘blank’ at the start of CØ minimum
green.
d.
If going AØ → CØ or B3Ø → CØ, with a
demand for P4, hold SG8 red for the duration of Timer 1 (Special Purposes
Timesetting No. 17).Timer 1 starts
timing at the start of P4 walk.When
Timer 1 expires, SG8 red is switched off.
e.
If going B1Ø → CØ or B2Ø → CØ, with a
demand for P4, SG8 goes red at the start of BØ all red period and SG8 is held
red for the duration of Timer 1 (Special Purpose Timesetting No. 17).Timer 1 starts timing at the start of P4
walk.When Timer 1 expires, SG8 red is
switched off.
f.
CØ ECO is used to guarantee SG8 minimum blank
period.Timer 2 (Special Purpose
Timesetting No. 21) starts timing at the start of SG8 blank period.When Timer 2 expires, expire CØ ECO.
g.
If in CØ, clear demands for BØ placed by detector
11.
Signal Group 9
1.
SG9 is controlled by Special Movement Timesetting
No. 4 within BØ.
BØ all red timesetting is substituted for Special Movement
Timesetting No. 4.
