Multifractal scaling analyses of urban street network structure: The cases of twelve megacities in China

Abstract: Traffic networks have been proved to be fractal systems. However, previous studies mainly focused on monofractal networks, while complex systems are of multifractal structure. This paper is devoted to exploring the general regularities of multifractal scaling processes in the street network of 12 Chinese cities. The city clustering algorithm is employed to identify urban boundaries for defining comparable study areas; box-counting method and the direct determination method are utilized to extract spatial data;… Show more

“…A variety of parameter estimation methods exist, including the ordinary least squares method (OLS), maximum likelihood method (MLM), etc. [ 28 ]. In this paper, we have chosen to use OLS and fix the intercept at 0 during regression [ 46 ].…”

“…At the spatial level, the spectra under positive moment orders correspond to central or high-density areas in a city, while those under negative moment orders correspond to marginal or low-density areas [ 17 ]. It has been observed that the spectra under positive moment orders exhibit similarities across different cities, while the spectra under negative moment orders display significant variations between cities [ 28 , 29 ]. This distinct growth pattern of spectra suggests that central areas represent stable zones for urban development, while marginal areas are the most dynamic regions for urban growth.…”

“…As paths got reinforced and cities evolved, the process took place in a non-uniform way, leading to different growth rates in the system. This produced a multifractal organisation of the street network [ 85 , 86 ], and of urban systems in general [ 87 ]. The self-organised processes, together with top-down interventions are responsible of the observed morphologies of cities.…”
