Luminance Contrast

• Is a measure of the difference in light being reflected onto two surfaces
• Assists community members who suffer from varying degrees of vision impairment
• When sufficient, serves as a visual warning of impending hazard such as
• Edges of railway station platforms
• Bus stops
• Kerb ramps
• Stairs

• ≥ 45% Luminance Contrast of discrete TGSIs (single cones) to path of travel
• ≥ 60% Luminance Contrast of path of travel and discrete TGSIs - which have differing materials for top surface and sides
• 24 to 25mm Ø TGSIs raised surface
• Apply to both Natural & Artificial Lighting
