sign visibility legibility

Detecting and reading traffic signs: sign detection and recognition distance, legibility distance, character height and font, retroreflective sheeting and luminance, and contrast needed to read signs day or night. Concerns the visibility and readability of signage specifically, distinct from general low-light visual function (dark_adaptation_mesopic) and the underlying contrast-detection ability (contrast_sensitivity).
