Bus
The Seoul Metropolitan Government operates newly designed buses on the newly adjusted routes as of July 1, 2004. New bus stop signs are easily recognizable as they are colorized according to the type of city buses: Blue, Green, Red and Yellow.
Taxis
Taxis are plentiful, clean, safe, and inexpensive in Korea. There are three kinds of taxis -- general taxis, deluxe taxis, and call taxis. The last two types of taxis offer a higher standard of service compared to the first, but are more expensive. You cannot always expect a taxi driver to be fluent in English, so it is advisable to mention landmarks (many major hotels and attracts) near your destination. Vacant taxis have indicator lamps on in front of the assistant driver seat and on the roof.
