Streetscape Guidance
[Part E – Physical design and materials] Crossings 138
Corduroy paving
Application – corduroy should be used to
identify specific hazardous situations for
pedestrians including:
• The top and bottom of steps
• The foot of a ramp to an on-street light rapid
transit platform, but not any other ramps
• While national guidance illustrates where the
footway is to be shared-use with a segregated
path for cyclists, the results of future research
should conclude appropriate use
• On the approach to level crossings
Application – corduroy should not be used to:
• Identify segregated routes for pedestrians
and cyclists where ladder and tramline paving
should be used
• Demark shared space areas
• Provide a defined edge of kerb instead of a
kerb upstand

Layout criteria
Dimensions
• 400x400mm paving unit with rounded raised
ridges 6mm high, 20mm in diameter and
equally spaced at 50mm
Placement
• The placement should comply with the DfT’s
Guidance on the use of Tactile Paving Surfaces;
Figure 134: Corduroy paving at a side road
generally 800mm (two paving units) wide,
except for the approach to a level crossing
and should extend the full width of the steps,
ramp or footway
Colour
• Contrasting grey – charcoal grey is standard
on the TLRN unless this provides insufficient
contrast with surrounding footways
TLRN departures from national guidance
The following departures from national guidance
should be used by designers working on TLRN
schemes when designing corduroy paving:
• 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
