Streetscape Guidance
TLRN departures from national guidance
The following departures from national guidance
should be used by designers working on TLRN
schemes when designing tactile paving at
controlled crossings:
• Exceptionally, where the area covered in
tactile paving will be unnecessarily extensive
or illegible due to a high radii kerb line
combined with an abnormally wide crossing,
consideration should be given to cutting
the area of tactile paving to be consistently
800mm from the kerb edge. Each location is
to be assessed and approved by the technical
approvals manager individually at the detailed
level
• Research shows that partially visually impaired
people often use the contrasting colour of
tactile paving to guide them through the
streetscape. However, there is less evidence
that the specific colour used makes the space
more legible. As such, the use of alternative
contrasting coloured tactile paving will be
considered on a case-by-case basis, for
instance, in conservation areas or where the
‘standard coloured’ tactile paving does not
contrast with the surrounding paving
• The use of reduced width tactile tails and
tactile paving at the kerb edge (800mm instead
of 1,200mm). Research undertaken in 2010
by University College London concluded that
‘the blister profile is readily detectable when
it is 800mm wide’ as it will always capture a
person’s stride. We have therefore reduced
the width used for all tactile paving surfaces
from 1,200mm to 800mm; two rows of
400x400mm flags (reduced from three)
• The crossing of tactile tails can cause
confusion for visually impaired users, and
should be avoided. To avoid tails crossing, the
tail associated with the crossing with lower
pedestrian demand should be terminated at
least 800mm from the other tail
Recording departures from
national guidance
Consistency in application is of fundamental
importance for legibility and so any deviations
from national guidance and the national
approach to tactile provision should be carefully
justified.
Project files must record the reason for not
following the national guidance. This includes
recording how Streetscape Guidance has been
followed in respect of the aforementioned
departures from national guidance.
