The Redesigned DMRC Map is designed for accessibility, where every traveler including those with Colour Vision Deficiency can read it without any external help
The Map features a different kind of line for each Metro line on the map, and indicators next to each station name, and labelling of every line
The map is designed in a minimal way, keeping in mind the cognitive load principles and symbols were also redesigned to communicate effectively

Problem Statement
Problem Statement
• Colour blindness affects approximately 1 in 12 men (8%) and 1 in 200 (0.5%) women globally
• Color Blind people find it difficult to distinguish between colours and in rare cases are unable to see any colour at all
• The DMRC Map mainly uses colour coded lines for navigation and this poses a huge problem for those with colour vision deficiency. They are unable to read and understand the map and the main purpose of the map remains unfulfilled

Colour Blindness
Colour Blindness
Colour blind peopel may also have trouble telling the difference between certain colors or shades.
Some very rare forms of color blindness make a person unable to see any colors.
For most colour blind people their condition is genetic, usually inherited from their mother, although some people become colour blind as a result of other diseases.
Problems can arise across the entire colour spectrum potentially affecting perception of all reds, greens, oranges, browns, purples, pinks and greys. Even black can be confused as dark red, dark green or dark blue/purple.

Types Of Deficiencies
Types Of Deficiencies
Blue- green colour deficiency: Tritanopia: When one has no S cones. They can’t perceive blue light. They see mostly reds, light blues, pinks and lavender.
Red- green colour deficiency:
Protanopia: The L cones are missing. One can’t perceive red light. One mostly sees colors as shades of blue or gold. May easily confuse different shades of red with black.
Deuteranopia: The M cones are missing. One can’t perceive green light. One mostly sees blues and golds. May confuse some shades of red with some shades of green. May also confuse yellows with bright shades of green.
Monochromacy: Only one type of cone is present, or no cone is functional at all. The person has very limited or no ability to see color. Instead, the person sees the world in varying shades of gray.

Problems with current map
Problems with current map
Lines are easily confused by a colour blind -person as the thickness and shape is same
Lines are not parallel and are intersecting at odd angles
Proper marking for interchange stations is absent
Information is cramped closely

Different line shapes for each colour line to make it easy to differentiate even if the viewer is seeing the map in black and white.

Marking on each station to recognize the line name on which the station falls.
For example, R on each station that falls on the red line.

This map is fully comprehensible and all lines and markings are clearly differentiable even to a person who doesn’t see any colour at all.

Let's test with people
Printed the map in monochrome version, and approached random people in Delhi Metro for feedback

Bolder and Bigger Line Names
Marking for Interchange Stations, more prominent, and marking on station names
Changed similar line shapes, to avoid confusion
