Evolution, accessibility and dynamics of road networks in China from 1600 BC to 1900 AD

Abstract

Before the emergence of modern modes of transport, the traditional road infrastructure was the major historical means of carrying out nationwide socio-economic exchange. However, the history of transport infrastructure has received little attention from researchers. Given this background, the work reported here examined the long-term development of transport networks in China. The national road network was selected for study and the 3500 years from 1600 BC to 1900 AD was chosen as the study period. Indicators were designed for the maturity level of road networks and an accessibility model was developed for the paths of the shortest distance. The evolution of the road network in China since the Shang Dynasty (1600 BC) was described and its major features were summarized to reveal long-term regularities. The maturity level of the road network and its accessibility was assessed and regions with good and poor networks were identified. The relationship between China's natural, social, and economic systems and the road network were discussed. Our analysis shows that the road network in China has a number of long-term regularities. The continuously expanding road network follows a path of inland expansion especially towards the border areas. However, its coverage and accessibility are characterized by a core-peripheral configuration, which has close relationships with, not only the natural conditions, but also national defense and warfare. The centralization of national power, national land governance, postal transport, the transport of specialized cargos, and international trade are also related to the development of the road network. This research draws attention to the evolving regularities of transport networks.

Forest fragmentation in China and its effect on biodiversity

“…Roads cause forest fragmentation by dissecting intact forests, creating forest edges, decreasing patch connectivity and acting as a barrier to local species (Xu et al , ) (Table ). China's earliest roads can be traced back to 1600 BC, in the east and central regions, but now cover most parts of China and have expanded to some of the most remote parts in the west in recent decades (Wang, Ducruet & Wang, ). Highways have been established in 99.5% of towns and 92.3% of villages in China (Liu et al , ), while the length of motorways increased from 652 km in 1992 to 65000 km by 2010; only United States has more (Li et al , ).…”

The impact of rivers and lakes on urban transportation expansion: A case study of the century-long evolution of the road network in Wuhan, China

“…Therefore, this study adopts the shortest path model based on its focus on the urban road network structure itself. Traditional shortest path models, like the shortest distance matrices constructed by Jin et al [ 48 , 49 ] and Wang et al [ 38 ], are commonly employed: …”

Geographies of transport II

“…For César Ducruet (Ducruet and Beauguitte, 2014; Ducruet, 2016) the main contributions of (transport) geography to the interdisciplinary literature on network science lie not only in the slowing down of physicists’ hard-and-fast conclusions through critical reflexivity on data quality, meaningfulness of results and policy relevance. Equally important is its role in integrating space and time into network research, and recent research on road networks in China (Wang et al, 2015), on maritime transport (Ducruet, 2016) and aviation (Zhang et al, 2015) evidences transport geography’s potential in this regard. However, questions can be raised about how beneficial the dominance of graph theory and complex network analysis is to the geographical analysis of transport.…”
