This is often required, for example, when the pedestrian controller is close to an
intersection where it is beneficial to keep the pedestrian controller at vehicle green
during certain stages of the intersection controller to help the traffic entering and/or
leaving the nearby intersection.

Cableless Link

– Using the controller’s Master Time Clock and CLF facilities, the

controller can be given one or more ‘windows’ during the CLF cycle when it is
allowed to service the pedestrian demands. For the rest of cycle, the vehicle phase
remains at green.

UTC

– The ‘PV’ control bit from the instation holds the vehicle phase at green.

When the ‘PV’ bit is de-activated for a short period, the controller will service any
pending demand for the pedestrian phase.

Local Link

– The ‘PV1’ input from an adjacent controller holds the vehicle phase at

green. When the ‘PV1’ bit is de-activated for a short period, the controller will
service any pending demand for the pedestrian phase.

3.3 PEDESTRIAN DEMAND CONTROL

3.3.1 Introduction

In addition to pedestrian push buttons, the controller can be configured with ‘cycle
detectors’  and  ‘kerbside  detectors’.  The  controller  firmware  treats  ‘cycle  detectors’
and  ‘push-button  inputs’  the  same  and  both  should  be  configured  to  demand  the
phase in the usual way.

‘Kerbside  detectors’  allow  the  controller  to  cancel  the  demand  (and  switch  off  the
wait / demand indicator) if the pedestrian crosses before the pedestrian phase gains
right of way..

A  push  button  input  can  be  associated  with  a  specific  kerbside  input  in  order  to
determine  the  type  of  pedestrian  demand  inserted.  A  kerbside  input  can  be
associated with one or more push button inputs, or it can be associated with none in
which case it is only used to hold and cancel the demand.

processing performed by the firmware described in the rest of this section.
