Rumble strip 1.

The Korean government is extremely considerate of blind people; either that, or it has realized how distracting cellphones are to it's citizens. Whichever way, in seemingly every public place, most notably in subway stations and on sidewalks, trails of rumble strips line every possible direction. The patterns change depending on the appropriate action for each location. If marking a path, the tiles feature four strips, spanning the width of each and pointing in the direction of flow. If marking an intersection or a place of interest, the tiles feature 36 small bumps. These small bumps indicate a street crossing, subway platform, elevator buttons, to name a few.
