The effects of Seoul's suburban beltway on accessibility, residential development, and housing rents: a transport-land use simulation approach

摘要

This study investigates whether the Seoul beltway is contributing to the decline of the central city and encouraging urban sprawl, by analyzing the effects of the beltway on accessibility, urban residential development patterns, and housing rents. The simulation results show that, although Seoul's suburban beltway may contribute to raising monthly rents for the housing along the beltway catchment area, and to attracting households into the inner-ring suburbs from both the central city and the outer-ring zones, the magnitudes of these impacts are relatively minor, with 1 and 0.6 % increases in total housing stock and monthly rents, respectively, for the majority of municipalities along the beltway, suggesting that the beltway has little responsibility for urban sprawl.
