Rural mobility inequality is an important aspect of inequality-focused Sustainable Development Goals. To reduce inequality and promote global sustainable development, more insight is needed into human mobility patterns in rural areas. However, studies on rural human mobility are scarce, limiting our understanding of the spatial and social gaps in rural human mobility and our ability to design policies for social equality and global sustainable development. This study, therefore, explores human mobility patterns in rural China using mobile phone data. Mapping the relative frequency of short-distance trips across rural towns, we observed that geographically peripheral populations tend to have a low percentage of short-distance flows. We further revealed social gaps in mobility by fitting statistical models: as travel distances increased, human movements declined more rapidly among vulnerable groups, including …

Knowing how workers return to work is a key policymaking issue for economic recovery in the post-COVID-19 era. This paper uses country-wide time-series mobile phone big data (comparing monthly and annual figures), obtained between February 2019 and October 2019 and between February 2020 and October 2020, to discover the spatial patterns of rural migrant workers’ (RMWs’) return to work in China’s three urban agglomerations (UAs): the Beijing–Tianjin–Hebei Region, the Yangtze River Delta and the Pearl River Delta. Spatial patterns of RMWs’ return to work and how these patterns vary with location, city level and human attribute were investigated using the fine-scale social sensing related to post-pandemic human mobility. The results confirmed the multidimensional spatiotemporal differentiations, interaction effects between variable pairs and effects of the actual situation on the changing patterns of …

The idea of the modal shift has been central to transport policymaking in the past few decades. Fare-free public transport (FFPT) schemes are among the potential policy instruments that are expected to promote modal shifts. After the peak of the COVID-19 outbreak, FFPT schemes have been implemented in large tourist destination areas in China to attract visitors. However, although FFPT has been practiced across the globe, its effect on travel modal shifts and transport equity is still under scrutiny.

This article describes how national imaginaries of market reforms designed to accommodate fast-growing Chinese regions, collide with embedded formal and informal governance practices in less developed provinces. Whilst much of the literature examines the implications of new infrastructure on regional economics, the management of existing networks dominates decision-making in these more stagnant economies. Using interviews with key stakeholders involved in highway management in Heilongjiang across the provincial and local levels, this paper explores institutional change and persistence using path dependence and junctures as an organising lens. We find that the manner and timing of institutional changes are shaped by the need for political elites in the territorial governing body to reinforce their authority over the vertical functional systems within the jurisdiction. Institutional persistence beneath the …

Network morphological analysis has emerged as a tool to quantify street network structures, providing a nuanced foundation for evaluating their impacts on traffic safety. Yet, there is a lack of disaggregate-level evidence on the spillover effects and spatial heterogeneity of these impacts. This research conducts a comprehensive, disaggregate-level, multi-scale examination on the overall impacts of street network morphologies on traffic safety. Our study focuses on the frequency of traffic injury collisions over a five-year period across more than 190,000 street links in Greater London. We characterise street-link morphologies at local (0–1 km), meso (0–3 km), and city (0–8 km) scales using a spatial design network analysis. For each spatial scale, we apply extended auto-negative binomial models to examine the overall impact of street-link morphological characteristics on the injury collision frequency, considering both …

Governments worldwide have announced stimulus packages to remobilize the labor force after COVID-19 and therefore to cope with the COVID-19-related recession. However, it is still unclear how to facilitate large-scale work resumption. This paper aims to clarify the issue by analyzing the large-scale prefecture-level dataset of human mobility trajectory information for 320 million workers and about 500,000 policy documents in China.

We propose a conceptual framework for understanding the complex nature of the correlation between the living environment and intravillage activity-travel. Based on participant observations of 146 villages (2317 rural residents) in Guangdong, China, we find that the rural built environment is predominantly organised by the gemeinschaft cultural environment in which people locate their homes near ancestral halls to maintain the bonds with those who are identified as the Us and to separate themselves from the Other. Together with the impact of the social environment which brings about a dispersed distribution of household farmlands, the phenomenon of home-farmland separation is pervasive. Several transport-related issues are engendered from the rural living environment: (a) distorted time-space for other activities that improve rural residents’ quality of life; (b) land abandonment due to unwillingness to travel …

In this paper, we propose a conceptual framework to elucidate transport-related social exclusion (TRSE) in rural China. Drawing from participant observations across 146 villages in Guangdong (2643 rural residents), we illuminate the multifaceted nature of TRSE in Chinese villages. In term of interregional transport challenges, rural residents are socially excluded due to inadequate transport infrastructure and services. In contrast, within the microcosm of intravillage transport, residents adeptly harness available transport resources to craft exclusionary strategies.
