Abstract
Thomson(1977) proposed that the equilibrium status can exist among modes when each mode's attractivenesses' are equal. His theories key point is that when the equilibrium status is achieved the additional investment for individual car user such as constructing more roads or widening the existing roads, can lead to more congestion. That's the so called 'Downs-Thomson's Paradox. This paper is intended to demonstrate that the paradox is applicable to Seoul Metropolitan area. Before doing that job, we reviewed Downs-Thomson's paradoxes related Papers such as Mogridge's (1985) research for London case. and Seung Jea-Lee's(2004) research for Seoul. In conclusion, the equilibrium status that Thomson proposed can't be applied to Seoul Metropolitan area. because the suppressed demand's behaviour is different from real situation and that of in the theory.
