Statistical Characteristics and Community Analysis of Urban Road Networks

Abstract: Urban road networks are typical complex systems, which are crucial to our society and economy. In this study, topological characteristics of a number of urban road networks purely based on physical roads rather than routes of vehicles or buses are investigated in order to discover underlying unique structural features, particularly compared to other types of transport networks. Based on these topological indices, correlations between topological indices and small-worldness of urban road networks are also explo… Show more

“…As can be seen, TABLE Ⅲ shows how these networks rank in terms of their robustness. The WBC can measure how frequently a given node of URNs can be passed by the shortest paths of all OD pairs [3]. According to [27], a network is more robust if the proportion of nodes with high BC is lower, which means the WBC of a network can be related to the robustness of the network.…”

“…Urban road networks (URN) are crucial infrastructure components of urban transportation and constitute an essential backbone underpinning most social and economic activities [2,3]. Road traffic networks and infrastructure are vulnerable to disasters [4][5][6], however, some of which, like extreme weather events or earthquakes, can be so disruptive as to lead to a complete system failure [7,8].…”

“…ese results could be attributed to the increases in woodland, which offset the value of individual services lost by reducing cultivated land. A comparison of the traditional and landscape ecology planning schemes reveals that the latter can improve the area's comprehensive service function value, prevent the simple pursuit of grain production, and realize the modern land regulation goals of protecting biodiversity and improving rural ecological service functions and landscape value through natural resource protection [44], the biological restoration of the ecological environment, nonpoint source pollution control, and the construction of ecological networks and green infrastructure [45].…”
