NOTE The guidance path surface guides visually impaired people along a route when the traditional cues, such as a property line or kerb edge, are not available. It may also be used to guide people around obstacles, for example street furniture in a pedestrianized area. The surface is designed so that people can be guided along the route either by walking on the tactile surface or by maintaining contact with a long cane.

NOTE 2 The central delineator is normally intaHed along the length of the route dividing the pedestrian side from the cyclist side.
kerb upstand vertical upstand greater than or equal to 25 mm.
controlled crossing pedestrian crossing point such as a pelican, zebra, puffin and toucan crossing and traffic signalled junction with pedestrian phases.

segregated shared route footway shared by pedestrians and cyclists.
Products shall be manufactured to ensure that the profile of the whole tactile paving surface has the same dimensions as the profile of the individual products including any joints. When modules are laid in bonded or half bonded patterns, the layout of the surface profile shall ensure that the pattern is repeated without disruption, making due allowance for joint width between modules.
NOTE Information on the application of tactile surface indicators is given in Annex C. Detailed guidance on application and layout is given in Guidance on the use of tactile paving surfaces [1].
The sizes of products and their designation, according to module type, shall conform to Table 1. Colour The colour of blister surface products at controlled crossings shall be red. Colour evaluation for red products shall be in accordance with Annex D and the requirements of Table D.1. At uncontrolled crossings the blister surface products shall be any colour other than red (commonly a buff colour) which contrasts with the surrounding paving. Profile The profile of the blister surface shall comprise rows of flat-topped blisters 5 mm 0.5 mm high, spaced at approximately 65 mm in each direction, arranged to conform to the requirements of 4.1. Dimensions and pattern-repeat of blister surfaces for pedestrian crossing point products shall be in accordance with the relevant figures in Annex E (see Figure E.1 for module type 1, Figure E.2 for module type 2 and Figure E.3 for module type 3).
Corduroy hazard warning surface
The colour of corduroy hazard warning surface products shall be any colour other than red as red is restricted to the blister surface at controlled crossings (see 4.2.1).
