Color Guidance Lanes (Joo-haeng-yu-do-seon ): What are those bright pink and green lines on the road?

In the past, Koreean highways and city intersections were incredibly confusing. When approaching a largejuction (a place where multiple roads meet) , drivers had to quickly read multiple overhead signs. This confusion caused drivers to change lanes at the last minute, leading to severe traffic accidents.    In March 2011, a tragic and fatal traffic accident occurred at the Ansan Juction on the West Coast Expressway. A paassenger car and a cargo truck crashed simply because they were confused about which lane to take. In fact, this area always used to be a frequent car accident spot, with 20~30 traffic accidents occuring every year.  So Mr. Yoon Seok-deok, an employess of the Korea Expressway Corporation wanted to do something about this problem. One day, he went home and watched his children drawing pictures on the floor with colorful paint and crayons.  Watching them , a brilliant idea flashed in his mind: what if we colar the roads just like my children's drawings,...

In March 2011, a tragic and fatal traffic accident occurred at the Ansan Juction on the West Coast Expressway. A paassenger car and a cargo truck crashed simply because they were confused about which lane to take. In fact, this area always used to be a frequent car accident spot, with 20~30 traffic accidents occuring every year. 


So Mr. Yoon Seok-deok, an employess of the Korea Expressway Corporation wanted to do something about this problem. One day, he went home and watched his children drawing pictures on the floor with colorful paint and crayons. 

Watching them , a brilliant idea flashed in his mind: what if we colar the roads just like my children's drawings, so drivers can easily see where to go ? 

In the six months following the installation of the pink and green lines, accidents dropped to a miraculous total of just 3!

The Color Guidance Lane is a thick, brightly colored line painted directly on the center of the driving lane.


Color Meanings:

-Pink Line: If a road splits into one new direction (usually an exit to the right), a pink line is used to guide the car.

-Green Line: If the road splits into two different directions, a green line is added for the second direction (usually to the left).

All a driver has to do is follow the pink or green line on the ground to their destination without getting lost or confused! 



Pink is the main one. At a fork, pink marks the route peeling off. When two directions split at once, they use pink and green together — one color each, so you just pick your color and stay on it. Green also marks the way into rest areas.

The light blue and orange lines you'll see near toll gates are something else — those are for Hi-Pass, Korea's automatic toll system. Blue for regular vehicles, orange for trucks. That's actually part of why pink and green got chosen in the first place: those two weren't taken yet.

One thing to know. Legally, the white lane lines still outrank the colored line. The color is guidance, not command. In an insurance dispute, the white line wins.

There are now more than nine hundred of these on Korean expressways alone, and several countries have come to study the system.

Colorful lines drastically reduced accidents—the South Korean government officially changed the law. Today, these lines are installed all over the country and are even synced with navigation apps, making driving safely accessible for everyone.

How Cotton Came to Korea and Changed Korean Life (Mun Ik-jeom story)

Before Cotton: Clothes Were a Winter Problem Before cotton became common, ordinary Koreans mainly depended on hemp cloth . Silk was available, but it was expensive and mostly used by the upper class. Hemp was strong, but it was rough and did not keep people very warm. That was a serious problem during Korea's cold winters. This meant that many poor people suffered severely in winter, and in extreme cases some even died from the cold. After cotton was introduced, this situation changed dramatically. There is also an interesting story about how cotton first arrived in Korea. 1363–1364: The Seeds Came from Yuan China In 1363 , near the end of the Goryeo Dynasty, a Korean diplomatic mission went to the Yuan Dynasty , the Mongol-ruled dynasty in China. One official on that mission, Mun Ik-jeom , returned to Korea in 1364 with about ten cotton seeds. According to a well-known story, he hid the seeds inside a writing brush case (this is the famous anecdote), but it is important to note t...

How do you say "hello" and " Good-bye" in Korea? (The origin of Korean greetings)

  "Annyeong- ha seyo"  안녕하세요  Greeting when people first meet  When people meet at the first time, Koreans usually say "Annyeong-haseyo"  This is the same words "hello" or "How are you " in America.  The literal meaning of "Annyeong-haseyo" is Are you well and at peace? The origin of Korean greetings can be found in the Korean War. At the time people died of hunger or disease every day after waking up overnight. That's why people say hello to make sure they've been well all night long.  There is "Siksa hasyeot-eoyo?" with the same expression. This means literally "have you eaten" or "did you have a meal?", mostly elder people use this expression or we use these words around mealtime or right after.  So people usually respond  "yes I have" even if they haven't. This greeting pattern is similar to how English speakers usually respond to the question "how are you" with " Fi...
