Seoul’s Public Transportation System, Smooth Transfers, Happy Commuters


Hi, this is Yoon-Young Tahk, University Reporter for LG CNS.

The public transportation system in Korea is internationally known to be convenient even for those new to the country. Other countries often benchmark the public transportation system here for that reason as well. To introduce you to what it’s like, I decided to try Seoul’s public transportation and share my experience of the day. Let’s take a look.

The Free Transfer System between Buses and Subway Trains

Seoul’s transfer system dramatically changed in July of 2004, and LG CNS was in the center of this change. It’s been almost a decade since then and the travel charge methods have developed during those years from prepaid travel cards to deferred payment cards and even NFC payments through mobile devices. Many cities around the globe actually benchmark Seoul’s smart public transportation system, too. I personally use T-Money, one of many different types of prepaid travel cards. With this card, I can transfer between buses and subways for free and pay my fee based on the distance I travel through the system called AFC (Automated Fare Collection)


Today, I took both a bus and the subway to get to Hong-ik University from Guro, which is one of the most crowded parts of Seoul to travel through. Thanks to the free transfer system, the trip was very cheap and convenient. This system is one of the benefits you get for using a travel card. Basically you can transfer for free between the subway and all inner city buses as long as you make your transfer within thirty minutes after tagging your travel card to the sensor, which is what you do when you get off the first ride. You can get up to four free transfers in one trip, but you can’t take the same bus or subway line more than once in that time. Imagine transferring for free simply by using a travel card. Doesn’t it seem so convenient and reasonable?


This ‘free transfer system’ developed by LG CNS revolutionized the way Seoulites’ experience their public transportation system and is considered one of the biggest factors increasing passenger satisfaction. A study titled “Survey on Public Transportation Transfer” conducted by the Korea Transportation Safety Authority in March of 2012 showed the changes this system had made. They interviewed 10,680 people who used the public transportation system four times or more a week. 10,265 people, or over 99% of those polled, said they were using this free transfer system one or more times a week.


Among different categories, you can see that the most satisfying one is ‘transfer system,’ followed by ‘information on transfer’ and ‘transfer payment.’ This transfer system was developed though LG CNS’s ‘new travel card system.’ The table above clearly shows that Seoulites’ are enjoying their convenient transportation system.

The most impressive part about Seoul’s public transportation system is that they have such well structured and convenient ‘bus operation info boards’ and a ‘subway info system for passengers.’ These systems are also managed by FMS (Fleet Management System) which is a part of LG CNS’s integral transportation information system. This is a system where information about the estimated arrival time and current locations and conditions of buses and subway trains are collected in order to manage them more efficiently. The data is then provided to passengers so they can travel more conveniently.

LG CNS’s internationally recognized ‘Smart Transportation System’


LG CNS’s smart transportation solutions such as smart travel cards, free transfer system, and public transportation management system are recognized around the world for their convenience and excellence. As a result, LG CNS was chosen to build and operate the AFC and transportation systems in Bogota, the capital of Columbia. The project began in the end of 2011 with some of the sections now open to the public. The travel card system in Bogota, Columbia uses the AFC and BMS (Bus Management System) managing 12,000 buses and 40 bus lanes for tertiary express buses. LG CNS also passed the compatibility test for the ‘smart public transportation fare payment system,’ which is a huge project being planned by the Transportation Bureau of London, England. They are now about to choose the contractor for this project and hopefully they pick LG CNS so they can ease traffic problems and popularize the public transportation system in London.

It seems fair to say Seoul’s new transportation system based on LG CNS’s smart technology is next to none. I hope to see Seoul’s transportation system become the front runner of the worldwide public transportation revolution.
