Complexity analysis on public transport networks of 97 large- and medium-sized cities in China

Abstract

The traffic situation in Chinese urban areas is continuing to deteriorate. To make a better planning and designing of the public transport system, it is necessary to make profound research on the structure of urban public transport networks (PTNs). We investigate 97 large- and medium-sized cities’ PTNs in China, construct three types of network models — bus stop network, bus transit network and bus line network, then analyze the structural characteristics of them. It is revealed that bus stop network is small-world and scale-free, bus transit network and bus line network are both small-world. Betweenness centrality of each city’s PTN shows similar distribution pattern, although these networks’ size is various. When classifying cities according to the characteristics of PTNs or economic development level, the results are similar. It means that the development of cities’ economy and transport network has a strong correlation, PTN expands in a certain model with the development of economy.

Ecological construction and environmental management in large and medium-sized cities in the context of industry- city integration

“…"The 14th Five-Year Plan period will be a period when the main and secondary contradictions in ecological environmental protection in China will be transformed, and it will be a period when the stage differences [4][5]. While further promoting development, it will become the main line of ecological civilization construction in this period to achieve ecological and environmental protection [6].…”

Impact of Road Network Topology on Public Transportation Development

“…However, most existing works only analyze the relationship between the urban road network and public transportation from the perspective of the density of road network [11] but overlook the index that can evaluate the relationship of road connectivity with factors affecting public transportation. Studies on the layout structure of road networks often pay more attention to the measurement method [12] and characteristics [13][14][15] of road network topology, as well as the influence of the road network layout on the traffic efficiency and reliability of the traffic network [16], or the relationship between layout structure of road network and density of bus line network [17]. However, there are few studies on the relationship between layout structure of road network and urban public transportation.…”

The Evolution and Growth Patterns of the Road Network in a Medium-Sized Developing City: A Historical Investigation of Changchun, China, from 1912 to 2017

“…Network science provides powerful theoretical and practical tools to analyze the structure of complex networks. Many studies have used quantitative methods and techniques based on network theory to analyze diverse transportation systems, for example, urban street networks [1][2][3][4][5][6][7][8][9][10], public transport networks [11][12][13][14][15], rail and subway networks [16][17][18][19][20][21], highway networks [22][23][24], and airline networks [25][26][27][28][29]. These studies are helpful for analyzing the structural characteristics of transport networks and the development of transportation science and engineering applications.…”
