The objectives of this study encompass three aspects. First, it analyzes the Bangkok Mega-city Model in three subareas around the New Suvarnabhumi International Airport.4 Second, it analyzes the compact city policy to measure factors of the compact city based on affordable transportation costs related to household income, jobhousing balance, and facilities. Third, it analyzes household commuting travel using modeling displays with visual simulation. The results show that the compact city strategy can shed light on the lifestyle of residents in a mega-city. Moreover, the study reveals that the patterns of urban structure in the Bangkok Metropolis are close to the compact city concept, which means the residents utilize urban structure in an area not more than 20 kilometers distant from their residences. The study was designed to show the necessity of urban policy that pursues "a compact city" in the Bangkok Mega-city.
