The implementation of TOD in the metropolises of China is considered as one of the policies to alleviate urban ills such as road congestion, air pollution, and CHG emission and health disbenefit. The Chinese development of TOD has several distinguishable characteristics from Western and US TOD of which the three most notable are: the fast paced, large-scale urban rail system implementation and the high-density context of metropolitan areas in China. The scale and pace of building line and stations could be conceptualised to create successive “accessibility technology shock” to pre-existing urban areas where stations locate but also to existing station and their surrounding as accessibility in the growing urban rail network shift and redistribute accessibility at a very fast pace and scale.
Various models are in use to characterise the performance of TOD area (5Ds, node and place, “China TOD”). These models are mainly concerned with the station area and its surroundings, they mostly do not consider the strategic urban design impact of the urban rail network growth.
Using network science and network shape indicators we propose to develop a longitudinal systematic evaluation of the relationship between strategic urban design of the urban rail network impact on metro stations accessibility rank. This is the first study to conduct a longitudinal analysis of the topological fast evolution of a metro network. We will investigate the Shenzhen urban rail network topology and geography fast paced dynamic from the start of the first line in 2004 until 2025 the end of the current extension plan. This research aims at enhancing the understanding of such dynamics and the node-and place characterisation. It is hoped this research will contribute to strategic urban design tools to better understand TOD performance of station areas in the context of metropolitan Chinese city.
