timesetting is substituted for Special Movement Timesetting No.1. |
|
| XSF5
flag is used to set special maximum time for SG5 in DØ. This time is
accessible in Special Purpose Timesetting No.9. SG5 will be forced off after
a period equal to the DØ minimum green plus this special maximum. |

| SIGNAL
GROUP 6 |
|
|
|
|
| SG6
is controlled by a Special Movement Timer No. 2 within DØ. DØ All Red

| PEDESTRIAN
GROUP OPERATION |
|
|
|
|
| Pedestrian
1 |
|
|
| P1
calls AØ. |
|
|
| P1
can introduce anytime in D3Ø and at the start of AØ and can overlap D3Ø ->
AØ. |
|
| P1
can introduce anytime in AØ if XSF1 is set (Masterlink
only) |
|
| P1
introduces automatically at the start of SG2 if XSF2 is set. |
|
|
|
|
| Pedestrian
2 |
|
|
| P2
calls CØ. |
|
|
| P2
can introduce at the start of CØ. |

|
| OPERATION
OF ADVANCED WARNING SIGNS |
|
|
|
|
| Wait
State 7 (WS7) and Wait State 8 (WS8) drive the flashing “PREPARE TO STOP”
signs on the west and the east approaches of Bass Highway respectively. |
|
|
|
|
| Wait
State 7 (WS7) |
|
| · Drives the operation of two flashing “PREPARE TO STOP” signs
on the west approach of Bass Highway. |
|
| · Wait State 7 (WS7) is switched on at the start of AØ ECO when
transitioning from AØ -> BØ, AØ
-> CØ, AØ -> D1Ø or AØ -> D3Ø. |
|
| · Wait State 7 (WS7) switches off when SG1 is green in AØ or
D2Ø. |
|
| · The flashing “Prepare to Stop” sign is activated from a point
prior to SG1 closing down. This time is stored in AØ Early Cut-Off (ECO), and
is calculated as follows: |
|
|
Time
= (Time to travel to Stop Line – Time to travel
from nominal stopping distance to the Stop |
Line + Reaction Time) |
|
| =
(200/25) – 5 (i.e. SG1 Yellow Time) + 1.5 |
|
| =4.5 sec. |
|
|
|
|
|
| Wait
State 8 (WS8) |
|
| · Drives the operation of two flashing “PREPARE TO STOP” signs
on the east approach of Bass Highway. |
|
| · Wait State 8 (WS8) is switched on at the start of AØ ECO when
transitioning from AØ -> BØ, AØ -> CØ and AØ -> D1Ø or AØ -> D2Ø. |
|
| · Wait State 8 (WS8) switches off when SG2 is green in AØ or
D3Ø. |
|
| · Wait State 8 (WS8) is switched on at the start of AØ ECO if
transitioning from AØ -> BØ, AØ -> CØ, AØ -> D1Ø or AØ -> D2Ø. |
|
| · The flashing “Prepare to Stop” sign is activated from a point
prior to SG2 closing down. This time is stored in AØ Early Cut-Off (ECO), and
is calculated as follows: |
|
|
Time
= (Time to travel to Stop Line – Time to travel
from nominal stopping distance to the Stop |
Line + Reaction Time) |
|
| =
(200/25) – 5 (i.e. SG1 Yellow Time) + 1.5 |
|
| =4.5 sec. |
