-Blue Bus :
This type of buses will operate at higher speeds and access the median bus lane connecting suburban areas to downtown Seoul. The city government is partly in charge of its operation. The city has taken full consideration to introduce 3 kinds of buses belonging to the Blue Bus category: bendable bus, CNG (compressed natural gas) bus with a lower platform, and regular large-sized CNG bus. The blue color represents Seoul's skyline and Han-river to symbolize security and freedom.
-Green Bus :
Green bus will be flexibly operated by private bus companies, to connect major subway stations or bus terminals in downtown Seoul. It is similar with the city bus and the community shuttle bus currently in operation. Green stands for the mountains surrounding the city.
-Red Bus :
The red buses will be express buses designed specially for those commuting between downtown Seoul and the metropolitan area. The color red exudes energy of speed.
-Yellow Bus :
This bus will circle downtown Seoul and stop at stations for blue buses and major railway stations, as well as business, tourist and shopping areas. Yellow was selected for its dynamic and friendly image.
