“…Changchun's urban road networks had two visible evolution characteristics: on the one hand, the road network covered a growing area and expanded outward continuously; on the other hand, there were more and more road segments within the ring road. This is consistent with the results of studies of other cities [34,62]. However, considering the development stages, it is different from other cities that the Changchun road network presents a cyclical progressive evolution.…”

“…The urban road networks planned by the Japanese (1939, 1946) had higher  ,  , and  . These three indicators had limited benefits to characterize the road networks, which was the same as the findings in Zurich [34]. When investigating the relationship between the number of intersections, the number of road segments and the road length, we found that there was a significant, linear correlation among them.…”

“…The urban road networks planned by the Japanese (1939,1946) had higher α, β, and γ. These three indicators had limited benefits to characterize the road networks, which was the same as the findings in Zurich [34]. The statistical bulletin of national economic and social development of Changchun Bureau of Statistics gives the statistical data of urban road length, area, population (from 2001 to now), and private car ownership (from 2009 to now) from 2000 to now.…”

“…Based on previous research results [31,45,46], Masucci et al analyzed the robustness and centrality of self-organized and planned cities in London and Chicago and found that the planned city of Chicago was superior to London to some extent [47]. Casali et al analyzed the topological growth in the Zurich (Switzerland) road network and found changes over time [34].…”

“…Transportation is a minor subject in the system, and it is difficult to obtain data, especially in China; thus, research on the evolution of road networks is still limited. In particular, existing research mainly focuses on big and developed cities in the world such as Paris, London, Milan, Beijing, Shanghai, Hong Kong, and so on [30][31][32][33][34][35][36]. There are few reports on the analysis of medium-sized developing cities, such as Changchun studied in this paper.…”

Understanding the evolution and growth patterns of urban road networks helps to design an efficient and sustainable transport network. The paper proposed a general study framework and analytical workflow based on network theory that could be applied to almost any city to analyze the temporal evolution of road networks. The main tasks follow three steps: vector road network drawing, topology graph generation, and measure classification. Considering data availability and the limitations of existing studies, we took Changchun, China, a middle-sized developing city that is seldom reported in existing studies, as the study area. The research results of Changchun (1912–2017) show the road networks sprawled and densified over time, and the evolution patterns depend on the historical periods and urban planning modes. The evolution of network scales exhibits significant correlation; the population in the city is well correlated with the total road length and car ownership. Each network index also presents specific rules. All road networks are small-world networks, and the arterial roads have been consistent over time; however, the core area changes within the adjacent range but is generally far from the old city. More importantly, we found the correlation between structure and function of the urban road networks in terms of the temporal evolution. However, the temporal evolution pattern shows the correlation varies over time or planning modes, which had not been reported

Urban morphogenesis analysis based on geohistorical road data

Road networks result from a subtle balance between geographical coverage and rapid access to strategic points. An understanding of their structure is fundamental when it comes to evaluating and improving territorial accessibility. This study is designed to provide insight into the progressive structuring of territorial patterns by analyzing the evolution of road networks. Studying road network morphogenesis requires geohistorical data, provided here by historical maps from which earlier road networks can be digitized. A hypergraph is constructed from these networks by combining road segments into “ways” on the basis of a method for defining the continuity of road segments. Next, indicators are computed for these ways based on topological and geometrical features. The road patterns of three cities in the Burgundy Franche-Comte region of France (Dijon, Besançon, and Pontarlier) at three historical periods (the 18th, 19th, and twentieth centuries) are then analyzed. In this manner, their topological features and centrality characteristics can be compared from snapshots at different times and places. The innovative method proposed in this paper helps us to read features of the road patterns accurately and to make simple interpretations. It can be applied to any territory for which data is available. The results highlight the underlying structure of the three cities, reveal information about the history and the functioning of the networks, and give preliminary insights into the morphogenesis of those cities. Prospectively this work aims to identify the mechanisms that drive change in road networks. Detecting stability or variation in indicators over time can help in identifying similar behavior, despite geographic and cultural distances, as well as evolution mechanisms linked to specificities of each city. The study of road network morphogenesis can make a major contribution to understanding how road network structure affects accessibility and mobility.
