Strategic Placement of Route Information
Position braille labels at consistent intervals along raised route lines to maintain logical reading flow. Place station names directly adjacent to their corresponding stops rather than clustering text in corner legend areas. Orient braille text horizontally whenever possible to match standard reading patterns. Space labels at least 0.5 inches apart to prevent finger confusion during tactile exploration. Prioritize major transfer points with larger braille cells and additional descriptive information about connecting services.
Material Selection for Durability
Choose thermoformed plastic substrates like ABS or polycarbonate for outdoor installations requiring weather resistance. Select zinc-plated metals for high-traffic indoor environments where vandal resistance matters most. Apply protective UV coatings to prevent braille dot degradation from sunlight exposure over time. Test material flexibility to ensure raised elements won’t crack under temperature fluctuations. Consider substrate thickness of at least 0.125 inches to support proper braille dot formation and route line elevation.
Cost-Effective Production Methods
Use vacuum forming techniques for large-format maps requiring complex topographical features at reasonable costs. Implement laser cutting for precise braille dot placement and consistent raised line heights across multiple map copies.
