| 1.
PEDESTRIAN INTRODUCTION |
|
| |
|
|
| The
pedestrian cannot introduce in AØ. |
|
|
|
| |
|
|
|
|
| The pedestrian can introduce in BØ if there is no tram call and
SG1 & SG2 have gapped or wasted (unless special timers are used - see
paragraph below). |
| |
|
|
|
|
| The pedestrian can introduce at the start of CØ provided SG1
& SG2 are in extension and there is no tram call (SG1 & SG2 close
down at the start of BØ yellow). If the pedestrian was demanded prior to CØ,
it will introduce once the tram call has been removed (ie. the tram has
departed the stop line loop) or at the last instant of CØ, whichever comes
first. Any pedestrian demand placed during BØ intergreen or during CØ will
not be serviced until the next cycle. |

SPECIAL TIMERS |
|
|
|
|
|
| |
|
|
|
|
| The above describes the normal operation in which the
introduction of the pedestrian is delayed by a tram call. In some
circumstances however it may be desirable to force on the pedestrian when a
tram places a call via an advance detector. This type of operation is
achieved by the use of a special timer for each approach, namely timers 3 and
4. |
| |
|
|
|
|
| Timer
3 is reset and starts timing at the beginning of BØ. |
|
|
| While timer 3 is still timing in BØ, a tram call via detector 6
will delay the pedestrian (as for paragraph 1 above). After timer 3 has
expired in BØ a tram call via detector 6 will force on the pedestrian
provided: |
| |
a) the pedestrian demand was placed prior to
the tram call |
|
| |
b) SG1 and SG2 are in extension |
|
| |
c) there are no tram calls via detectors 7, 8
or 9. |
|
| |
| Timer
4 is reset and starts timing at the beginning of BØ. |
|
| While timer 4 is still timing in BØ, a tram call via detector 8
will delay the pedestrian (as for paragraph 1 above). After timer 4 has
expired in BØ a tram call via detector 8 will force on the pedestrian
provided: |
| |
a) the pedestrian demand was placed prior to
the tram call |
|
| |
b) SG1 and SG2 are in extension |
|
| |
c) there are no tram calls via detectors 6, 7
or 9. |
|
| |
| Timers
3 and 4 each have four timesettings which are selected by the Z flags (refer
Tram Priority Operation). |
| |
|
|
|
|
|
|
|
| If the value of a timesetting is larger than the length of BØ,
then a tram call will always delay the pedestrian introduction. |
| |
|
|

NOTE |
|
| |
| The
operation of DØ, EØ, and FØ are the same as for AØ, BØ, and CØ respectively. |

PEDESTRIAN WALK TIME SUBSTITUTION |
