Embossing Metro Route Map

Universal design, Group Project, 2012

In Korea, thousands of people are using public transportation to travel from a place to another. Most people do not have any problem using it at all except for those who have visual disturbance, for example, blindness, color blindness and color weakness. We have determined that the current subway route map is responsible for this phenomenon. They are thoroughly made for people who are perfectly normal people in disregard of those who has visual disturbance. If these people are on a first trip to a place, they can easily be misinformed or can not get any information at all when seeing current route map. Color blinds could lose track on the transfer point if they can not recognize color properly and blinds can not even read anything. So we came up with this idea to give people information whether their handicapped or not. We have given changes to line indication, from a line and colors to lines and colors. It is a simple idea but despite the color disturbance, one can see which line they are on and which line they need to transfer without any confusion. In addition, these lines are protruded out with stations translated in braille so blinds can also get the idea of station number to their destination and transfer point and follow the embossed lines to keep in track. Additionally, current route maps lines are made in angular, but our design is made in curves to prevent the blinds from losing track on the point that multiple lines are overlapping. In this way, route map for normal people and those with visual disturbance can be solved economically. In a way, it is much more convenient for normal people too, because not everyone is familiar with the colors of the metro lines unless they are using it frequently.

The blinds can understand the structure of the map by touching the emboss lines like they are reading braille and indicate the transferring points by sensing the points marked by thick circle.03 EmbossingRouteMap02

The color blinds can indicate the metro line not by the color but by the number of the lines. A thin line is equal to one, and thick line is equal to five. So up to 4 lines, you can think as you see and from 5, you can count the thick line (5) + thin lines (n). This idea was given to prevent the lines getting thicker.
