Abstract
The research on complex networks offers novel insight into the analysis of complex urban systems. The objective of this article is to provide a review of complex network theory in urban land‐use and transport studies to date. Some traditional integrated studies of urban land‐use and traffic networks are summarized and analysed; related research gaps were proposed. Then, this paper reviewed the application of complex network theory in urban land‐use and transport research and practice. It shows that the node importance identification method is critical for network protection or attack studies; the multiple centrality assessment and kernel density estimation approaches can be used to represent the intuitionistic connections of urban traffic networks and surrounding land‐uses; it can be used to verify the changing trend and variation of landscape connectivity; also it can be applied to the identification of key changed land‐use types in land‐use cover change; the coevolution process can be treated as an integrated way to discuss the relationships between urban traffic network growth and land‐use change, and the multilayer networks based analysis is a novel method to measure their interactions. This paper is essential in establishing apparent research interests and points out the further potential application of complex network theory in urban traffic network and land‐use related studies.
Highlights
Many investigations have shown that, in the complex urban system, traffic networks, city-size distributions, distribution of urban traffic flows, and human mobility follow scaling properties [1,2,3,4,5]
The traditional literatures of the land-use and transport interaction research are not limited by date; the literature based on complex network theory is limited to the past 18 years (2001-2019)
This paper focuses on the application of complex network theory in urban traffic network and land-use based researches and practices, to fill the gaps which are existing in recent land-use and transport interaction studies
Summary
Many investigations have shown that, in the complex urban system, traffic networks, city-size distributions, distribution of urban traffic flows, and human mobility follow scaling properties [1,2,3,4,5]. The viewpoints of the small-world network and scale-free network changed the thinking of urban traffic networks: before these two models were proposed, traffic networks were normally approached as regular networks and ER random networks [16], as inherited from the definitions of graph theory. I will review these traditional studies that integrate the urban land-use and traffic network These studies grasp the structural defects and existing problems and demonstrate the benefit of clearly positioning the role of new techniques and methods, such as complex networks, in urban design and planning processes. Complex network-related land-use research will be further discussed, such as the application of determining the important nodes in urban land-use planning This will be followed by the direct or indirect applications of complex network theory in land-use and revelations of the management of land-use for the identification of the key changed land-use types in land-use cover change (LUCC). A summary of this article and future outlooks are presented
