Study on land use characteristics of rail transit TOD sites in new towns-taking Singapore as an example

In order to understand the land use characteristics of the rail transit station sites in new towns of high-density Asian city, this study selected six rail transit stations in Singapore as the research objects. Through the GIS spatial analysis, the study analyzes the rail transit sites in the new town centers and private residential areas, as well as the similarities and differences between Urban TODs and Neighborhood TODs, with consideration to two spatial structure forms of Singapore's new towns. The study finds out that the rail transit station sites in Singapore's new town centers have gradually formed a specific TOD land use model for Asian transit village. The urban center hierarchy and the new town development concept have led to the difference in land use characteristics of the TOD stations. It is suggested that the mixed-use development of the TOD station area should be tailored to local conditions and a certain proportion of public service facilities, parks and open spaces should be guaranteed, to achieve sustainable development of land economy, environment and society.
