A Retroreflective Route Board is a type of signage used primarily in transportation systems such as roads, highways, or railways to guide travelers and provide directional information. These materials contain tiny glass beads or prisms that reflect light back to its source, enhancing visibility and legibility, especially at night or in low-light conditions. The retroreflective material is resistant to fading, cracking, peeling, or degradation over time, ensuring that the signage maintains its effectiveness for extended periods. Retroreflective Route Board offers a cost-effective solution for providing directional information and guiding travelers on transportation networks.
