Urban Village Redevelopment Projects in China
The dual land system that resulted from the 1982 land reform makes the Chinese land situation unique. A dichotomy has existed between the state ownership of urban land and public ownership of rural land ever since. Urbanization in China often takes place by penetrating spatially into rural villages, where land is collectively owned. Urban villages are often regarded as temporary entities with undesirable urban planning and governance. Combined with the negative social externalities that urban villages emit, the Chinese government has implemented large-scale urban village redevelopment projects (UVRPs) in recent years to replace shabby entities with formal urban neighbourhoods. This phenomenon is in line with Kochan’s argument that urban planners will ultimately eradicate urban villages in urbanization. UVRPs have stimulated rapid urban development, which plays a great role in economic growth and modernization.

Urban Vacant Land
Rising housing prices and the growing impacts of climate change demand a rethinking of the revision of consolidated paths to housing development in cities. The mutual influence between urban housing and climate resilience policies is indeed one of the most pressing topics to rediscuss the contemporary form of cities. Indeed, the literature widely agrees that a more environmentally conscious urban form implies denser, mixed-use neighborhoods than the mono-functional districts that have characterized most modern cities. At the same time, the need for compact urban environments must coexist with the emergence of climate resilience features that require more open-to-nature layouts to implement passive strategies and on-site green infrastructure.

Urban Trees in Mitigating Climate Impacts
Urban tree cadastres, essential for climate adaptation and urban planning, face challenges in maintaining accuracy and completeness. Existing urban vegetation has a large cooling potential. However, it is important to note that all tree species emit varying concentrations of biogenic volatile organic compounds (BVOCs) (e.g. isoprene and terpenes), which can act as precursors for the formation of ground-level ozone.

Urban Transportation Meteorological Observation
With the advantages of various advanced technologies from multiple aspects, researchers could further expand explorations on urban transportation meteorological observations. Associated theoretical studies and practical investigations are also to be carried out to provide solid scientific foundations for urban transportation disaster prevention and mitigation, for implementing the action of meteorological guarantees, and for the construction of a high-quality smart society.

Urban Traffic Signal Control under Mixed Traffic Flows
Mixed traffic flows are opening up new areas for research and are seen as key drivers in the field of data and services that will make roads safer and more environmentally friendly. Understanding the effects of Connected Vehicles (CVs) and Connected Autonomous Vehicles (CAVs), as one of the vehicle components of mixed traffic flows, will make it easier to avoid traffic congestion and contribute to the creation of innovative applications and solutions.

Urban Spatial Structures in Historic Cities
The role of culture in urban competitiveness is becoming increasingly important. How historic cities identify and protect the spatial structures formed since ancient times, which are the carriers of urban culture, has become an important issue.

Urban Spatial Plan Impact on Land Value
The availability of different types of zoning in cities due to urban planning, urban development, and design creates many problems, including land value and land price problems. On the land value side, several factors affect the land studied to determine its value. On the land price side, there is an exploratory reverse relation between land supply and its cost; an increase in supply leads to a reduction in land cost, while a lack of supply leads to a high price of land until the time comes that supply is equal to demand which is the satisfaction point.

Urban Sociology
Urban sociology is the sociological study of life and human interaction in metropolitan areas. It is a normative discipline of sociology seeking to study the structures, environmental processes, changes and problems of an urban area and by doing so provide inputs for urban planning and policy making. In other words, it is the sociological study of cities and their role in the development of society. Like most areas of sociology, urban sociologists use statistical analysis, observation, social theory, interviews, and other methods to study a range of topics, including migration and demographic trends, economics, poverty, race relations and economic trends. Urban sociology is one of the oldest sub-disciplines of sociology dating back to the mid-nineteenth century. The philosophical foundations of modern urban sociology originate from the work of sociologists such as Karl Marx, Ferdinand Tönnies, Émile Durkheim, Max Weber and Georg Simmel who studied and theorized the economic, social and cultural processes of urbanization and its effects on social alienation, class formation, and the production or destruction of collective and individual identities. These theoretical foundations were further expanded upon and analyzed by a group of sociologists and researchers who worked at the University of Chicago in the early twentieth century. In what became known as the Chicago School of sociology the work of Robert Park, Louis Wirth and Ernest Burgess on the inner city of Chicago revolutionized not only the purpose of urban research in sociology, but also the development of human geography through its use of quantitative and ethnographic research methods. The importance of the theories developed by the Chicago School within urban sociology have been critically sustained and critiqued but still remain one of the most significant historical advancements in understanding urbanization and the city within the social sciences. The discipline may draw from several fields, including cultural sociology, economic sociology, and political sociology.
