Approximately 8% of men and 0.5% of women worldwide are color blind. This means that around 4.5% of the total population experiences some form of color vision deficiency. The most common type is red-green color blindness, which affects the ability to distinguish between reds, greens, and browns—exactly the issue with current traffic maps.
Given these numbers, millions of people would benefit from more accessible indicators.
To enhance accessibility, I suggest incorporating additional visual indicators such as:
Patterns or Textures – Different road textures (e.g., diagonal stripes for slow traffic, dots for moderate, solid for smooth flow) could help differentiate congestion levels.
Symbols or Icons – Small icons (e.g., a snail for slow traffic, a turtle for moderate, a rabbit for fast-moving) could provide clarity.
Line Thickness – Varying line thickness to represent traffic density could be an intuitive alternative.
Gradient Shading – Using grayscale variations instead of color could help convey traffic flow.
Blinking or Animation – Subtle pulsing or blinking effects on slow-traffic sections could enhance visibility.
Audio or Haptic Feedback – An option to announce traffic conditions or use vibrations in navigation could further assist users.
These enhancements could greatly improve the experience for millions of color-blind users. I’d love to see these ideas considered in future updates!
