|
| GENERAL OPERATION |
|
|
|
| · If in AØ, clear demands for DØ when SG5 & SG6 are
partially controlled (06:30 -> 09:30, 15:30
-> 18:30 Monday -> Friday). If
transitioning from AØ -> DØ (due to Master
data), run D1Ø when SG5 & SG6 are partially
controlled. |
|
| ·
Late start SG7 in BØ when transitioning from AØ
-> BØ while SG5 is partially controlled (06:30
-> 09:30, 15:30 -> 18:30 Monday -> Friday). SG7 introduce at the start of BØ when
transitioning from CØ -> BØ or DØ -> BØ. SG7 introduce at the start of
BØ when SG5 is full controlled. |
| · Expire AØ late start period and AØ ECO period when both SG5
& SG6 are fully controlled. |
|
| · Substitute AØ yellow for DØ yellow when transitioning from D2Ø or D3Ø
to phases other AØ. |
|
|
|
|
|
| SIGNAL GROUP OPERATION |
|
|
|
| SIGNAL GROUP 5 |
|
|
|
| · SG5 is controlled by Special Movement Timer No. 1 within
DØ. DØ all red timesetting is
substituted for Special Movement Timer 1. |
|
| · XSF5 is used to set the maximum time for SG5 & SG8 in
DØ. This time is accessible in Special
Purpose Timesetting No.12. SG5 &
SG8 will be forced off after a period equal to the DØ minimum green time plus
this maximum time. |
|
|
|
| SIGNAL GROUP 6 |
|
|
|
| · SG6 is controlled by Special Movement Timer No. 2 within
DØ. DØ all red timesetting is
substituted for Special Movement Timer 2. |
|
| · XSF6 is used to set the maximum timer for SG6 in DØ. This time is accessible in Special Purpose
Timesetting No. 13. SG6 will be forced
off after a period equal to the DØ minimum green time plus this maximum time. |
|
|
|
| SIGNAL GROUP 8 |
|
|
|
| · SG8 is controlled by Special Movement Timer No. 3 within
DØ. DØ special all red timesetting is
substituted for Special Movement Timer 3. |
|
|
|
| RED ARROW DROP OFF OPERATION |
|
|
|
| · SG5 and SG6 operate as fully controlled right turns during the
following periods: |
|
| o
00:00 -> 06:30 |
Monday -> Friday |
|
| o
09:30 -> 15:30 |
Monday -> Friday |
|
| o
18:30 -> 24:00 |
Monday -> Friday |
|
| o
00:00 -> 24:00 |
Saturday & Sunday |
|
|
|
| · SG5 and SG6 operate as partially controlled right turns with
red arrow drop-off during the following periods: |
|
| o
06:30 -> 09:30 |
Monday -> Friday |
|
| o
15:30 -> 18:30 |
Monday -> Friday |
|
|
|
| SIGNAL GROUP 5 – Fully Controlled Right Turn |
|
| · Place a demand (once only) for SG5 at 09:30 and 18:30 Monday -> Friday. |
|
| · SG5 remains red in AØ. |
|
| · Detector 3 places locking calls for DØ and extends DØ. |
|
|
|
| SIGNAL GROUP 5 – Partially Controlled Right Turn (Red Arrow Drop
Off Operation) |
|
| · SG5 operates green/yellow/red in DØ and can be switched to
blank during AØ. |
|
| · If there is no demand for P1 in AØ, SG5 red will be switched
off at the end of AØ late start period. |
|
| · If P1 runs in AØ, SG5 is held red in AØ for the duration of
Timer 1 (which starts timing at the start of P1
walk using Special Purpose Timesetting 9). When Timer 1 expires, SG5 red is switched
off in AØ if it is later than AØ late start period. |
|
| · AØ ECO is used to guarantee SG5 minimum blank period in
AØ. Timer 2 (Special Purpose Timesetting 10)
start timing at the beginning of SG5 blank period. When Timer 2 expires, expire AØ ECO period
from this approach. |
|
| · SG5 red will remain red in DØ if SG5 gaps. |
|
| · SG5 goes red at the start of SG1 red in AØ. |
|
| · SG5 is held red in BØ and CØ. |
|
| · Detector 3 places locking calls for AØ and places non-locking
calls for DØ when the presence time for detector 3 expires. |
|
| · Detector 3 extends DØ. |
|
|
|
| SIGNAL GROUP 6 – Fully Controlled Right Turn |
|
| · Place a demand (once only) for SG6 at 09:30 and 18:30 Monday -> Friday. |
|
| · SG6 remains red in AØ. |
|
| · Detector 5 places locking calls for DØ and extends DØ. |
|
|
|
| SIGNAL GROUP 6 – Partially Controlled Right Turn (Red Arrow Drop
Off Operation) |
|
| · SG6 operates green/yellow/red in DØ and can be switched to
blank during AØ. |
|
| · SG6 red will be switched off at the end of AØ late start
period. |
|
| · AØ ECO is used to guarantee SG6 minimum blank period in
AØ. Timer 3 (Special Purpose Timesetting 11)
start timing at the beginning of SG6 blank period. When Timer 3 expires, expire AØ ECO period
from this approach. |
|
| · SG6 red will remain red in DØ if SG6 gaps. |
|
| · SG6 goes red at the start of SG2 red in AØ. |
|
| · SG6 is held red in BØ and CØ. |
|
| · Detector 5 places locking calls for AØ and places non-locking
calls for DØ when the presence time for detector 5 expires. |
|
| · Detector 5 extends DØ. |
|
|
| OPERATION OF DUMMY SIGNAL GROUP 9 |
|
|
|
| 1. The introduction of SG9 is determined by delay timers, T1
& T2. |
|
| 2. T1 starts timing at the start of SG3 green. |
|
| 3. T2 starts timing at the start of SG3 yellow. |
|
| 4. SG9 goes green when T1 expires (Special
Purpose Timesettings No. 22, 24 & 26 subject to XSF flags). |
|
| 5. SG9 goes yellow when T2 expires (Special
Purpose Timesettings No. 23, 25 & 27 subject to XSF flags). |
|
| 6. Use Yellow and All-Red of running phase for SG9. |
|
| 7. SG9 will remain red when XSF9 is set |
|
|
|
| The degree of saturation of Detector 10 during SG9 green can be
used to push the percentage of CØ in Masterlink. |
|
|
|
|
|
| PEDESTRIAN GROUP OPERATION |
|
|
|
| Pedestrian 1 |
|
| P1 calls AØ. |
|
| P1 can introduce at anytime during D3Ø and at the start of AØ and
can overlap from D3Ø -> AØ. |
|
| P1 can introduce anytime during AØ while XSF1 is set (Masterlink only and when SG5 is fully controlled). |
|
| P1 auto introduces at the start of SG2 when XSF2 is set (all modes). |
|
|
|
| Pedestrian 2 |
|
| P2 calls CØ. |
|
| P2 can introduce at the start of CØ. |
|
| P2 is permanently demanded when XSF3 is set. |
|
|
|
|
|
| DETECTOR OPERATION |
|
|
|
| Clear vehicle demands during associated phase green and yellow. |
|
|
|
| Detector 6 |
|
| Detector 6 extends CØ & DØ when its presence timer expires and if XSF4 set. |
|
| If Detector 6 alarms, ignore functions of Detector 6 when XSF4 is
set. |
|
|
|
| Detector 10 |
|
| Detector 10 is a queue loop. |
|
| Reset presence timers for detector 10 when T1 expires, and then: |
|
| When presence time for detector 10 expires (when
SG9 is green), set MSS10. MSS10 will be set for the duration of
detector 10 being occupied while SG9 is green. |
|
| If detectors 10 alarms, then clear the MSS10 flags and inhibit
detector from extending CØ. |
|
| Inhibit detector 10 from carrying above if XSF9 is set. |
