3.7.4.10 The location of the crossing point at signal controlled junctions with a pedestrian phase is
important on the positioning of the dropped kerb. In many occasions kerbs have been
dropped around the complete radius of the kerbs between the major and minor roads.
Unfortunately this tends to encourage vehicles to negotiate the curve much closer to the kerb
than they normally would. Therefore, the crossing should be aligned so that the tangent
point of the radius on the minor road is the point where the kerb is first ramped down to
form the dropped kerb. For large radius curves, however, this may mean that the crossing is
located along the minor road footway away from the normal path of pedestrians and with
insufficient reservoir width for pedestrians waiting to cross. In these latter instances the
crossing may be positioned closer to the minor road, but the dropped kerbs should not
extend along the circumferences of the kerb radius for more than half its length. However in
many locations there is also an adjacent crossing on the major road and the adjustment of
the crossing on the minor road can result in the dropped kerbs of both crossings coinciding.
If the crossing on the major road cannot be set further back to avoid this, at least 2m and
preferably 3m of raised kerbs should be provided between adjacent crossings.
3.7.4.11 As with other crossings it is essential that there is adequate reservoir space at the side of the
road and within any refuge island provided for pedestrians to wait without encroaching onto
the carriageway and without obstructing the movements of other passing pedestrians.
3.7.4.12 Audible traffic signals must be provided at signal light controlled crossings to assist visually
impaired persons. For details of operation hours, refer to Volume 4 Chapter 4.
