Corduroy Tactile
The purpose of the corduroy surface is to warn visually impaired people of the presence of hazards, such as stairs, level crossings or the approach to on-street light rapid transit (LRT) platforms. Consisting of rows of parallel half-round bars, it conveys the message “hazard, proceed with caution”.
Blister Onstreet Tactile
The purpose of the blister surface is to provide a warning to visually impaired people who would otherwise, in the absence of a kerb upstand, find it difficult to differentiate between where the footway ends and the carriageway begins. The surface is therefore an essential safety feature for this group of road users at pedestrian crossing points.
Blister Offstreet Tactile
This design has flat topped domes set in evenly spaced rows parallel to the direction of travel along the platform. The offset of the domes indicates the direction of travel to the train. Used adjacent to safe carriageway crossings, the surface can be any colour other than red, but should provide a good contrast with the surrounding area to assist partially sighted people.
