Lozenge Warning Surface for On-Street Tram
The on-street tram and light rail platform edge warning surface is designed to alert visually impaired individuals to the proximity of platform edges in public road environments where trams or rapid light rail (TLR) operate. This surface enhances pedestrian safety by providing a detectable warning before reaching the platform edge.
To ensure visibility and effectiveness, this surface must be installed exclusively on tram and light rail platforms located on public roads, in areas where warning about the platform edge is essential. It should also be implemented in a visually contrasting color against the surrounding pavement to improve detection for both visually impaired individuals and general pedestrians.

- Install on tram or rapid light rail platforms located on public roads.
- Implement in areas where it is crucial to warn about the proximity of the platform edge.
- Ensure visual contrast with the rest of the pavement to improve detection.
