A TOD perspective on the urban spatial structure and travel behavior in the Guangdong-Hong Kong-Macao Greater Bay Area
Principal Investigator: Prof. Donggen Wang (Department of Geography)

Land use policies have been important strategies to reduce car dependency and facilitate travel. In recent years, Chinese cities have witnessed two important developments: substantial improvements in public transport infrastructure especially the development of underground railways and the agglomeration of cities. These trends of urban development bring substantial changes in the travel behavior of urban residents. On the one hand, Transit-Oriented Development (TOD) stations have gradually become the essential activity space in individuals’ daily life; on the other hand, the development of inter-city transportation system facilitates the travels between adjacent cities, thus greatly expands the activity space of residents. Most of previous land use-transport studies are limited to a single city. Besides, they typically take the residential neighborhood as the basic spatial unit of analysis, and consider TOD as a simple built environment attribute. This research investigates the changes of urban forms and travel behaviors in the Guangdong-Hong Kong-Macao Greater Bay Area. It extends current land use-transport research from neighborhood-based to TOD-based, and broadens the spatial scale of analysis from a single city to the Greater Bay Area. The findings of our case study will provide important implications for the development of China’s urban and transportation systems in the new era.
