Precise Simulation

The precise simulation of urban space evolution and grasping of the leading factors are the most important basis for urban space planning. However, the simulation ability of current models is lacking when it comes to complicated/unpredictable urban space changes, resulting in flawed government decision-making and wasting of urban resources. In this study, a macro–micro joint decision model was proposed to improve the ability of urban space evolution simulation. The simulation objects were unified into production, living and ecological space to realize “multiple planning in one”. For validation of the proposed model and method, remote sensing images, geographic information and socio-economic data of Xuzhou, China from 2000 to 2020 were collected and tested. The results showed that the simulation precision of the cellular automata (CA) model was about 87% (Kappa coefficient), which improved to 89% if using a CA and multi-agent system (MAS) joint model. The simulation precision could be better than 92% using the prosed model. The result of factor weight determination indicated that the micro factors affected the evolution of production and living space more than the macro factors, while the macro factors had more influence on the evolution of ecological space than the micro factors. Therefore, active policies should be formulated to strengthen the ideological guidance towards micro individuals (e.g., a resident, farmer, or entrepreneur), and avoid disordered development of living and production space. In addition, ecological space planning should closely link with the local environment and natural conditions, to improve urban ecological carrying capacity and realize urban sustainable development.

The City

The article analyzes urban representations of Soviet-era Lithuanian cinema. Like any other object of reality, the city in cinema is a secondary reality, the fruit of artistic interpretation. At the same time, images of the city in film can reflect individual and collective consciousness of the period. The analysis of urban space of Lithuanian feature cinema reveals that cinematographic space can be treated as a composite construct, which creates and represents projections of identities and feelings, reflects demands, ideas, cinema fashions of its time and “hides” real sociocultural and sociopolitical discourses. Most of Soviet-style feature films much easier incorporate countryside spaces, images, landscapes and lifestyle. Meanwhile the city often not only creates an impression of a claustrophobic space, but even looks very decorative. It seems that most of filmmakers can’t identify cities with their own, Lithuanian, national living space. In search of identity or inspiration they turn to idealized village, agrarian culture and its images. Therefore, the city of Soviet Lithuanian cinema is more likely to become a space of collapsed hopes, prison, ideological repressive space, which is stuck between the present and the past. Filmmakers, like their characters, run to the shelter of nature, the mythologized, well-decorated farmstead, where archetypal father and mother figures or a calm, meditative landscape await. It seems that movie characters (and filmmakers), who have escaped from the socialist reality and its challenges to the landscapes of nature and village, have never returned.

Grey Relational

The appearance of urban space is most often determined by planners, urbanists, and officials who fail to consider social preferences in the planning process. According to recent scientific research, spatial design should take into account people’s preferences with regard to its shape, as it is they who are the target audience. Moreover, legal regulations in many countries require the public’s inclusion into the space planning process. This paper outlines the legal status of the issue of social participation in spatial planning and provides an overview of the methods and techniques applied in the research into preferences. The aim of the article is to determine the strength of the relationship between the features adopted for the study using the grey system theory and to investigate the model’s behaviour for varied input data. It also presents the results of a study into the effect of geospatial features on the perception of the sense of security within urban space. The features were extracted using a heuristic method for solving research problems (i.e., brainstorming) and the survey was conducted by the point-scoring method. The survey results were processed by the grey system method according to the grey system theory (GST) of the grey relational analysis (GRA) type to yield a sequence of the strength of dependence between the analysed features. The study was conducted five times, with the order of entering the survey results being changed. The conducted analyses indicated that a change in the order of data from particular surveys applied for calculations resulted in the order of the epsilon coefficients in the significance sequences being changed. The analysis process was modified in order to obtain a stable significance sequence irrespective of the order of entering survey results in the analysis process. The analysis results in the form of a geospatial feature significance sequence provide information as to which of them have the greatest impact on the phenomenon under consideration. The research method can be applied to solve practical problems related to social participation.

The City

‘Text’ has been a frequent notion in analytical conceptualizations of landscape and the city. It is mostly found in analyses of textual representations or suggestions concerning a metaphor of “reading” an (urban) landscape. In the Tartu- Moscow School of Semiotics the idea of the text of St. Petersburg has also been applied in analysing particular cities as organizing topics in literature and in culture more widely, but it has not happened to an equal degree in studies of actual urban spaces. The understanding of text as a semiotic system and mechanism is, however, more promising than revealed by these conceptions. Some potential can be made apparent by relating this textual paradigm to a more pragmatic understanding of the city and its planning. My project in this paper is to uncover an analytical framework focusing on the concepts of ‘text’, ‘textualization’ and ‘texting’ in studying the planning of urban environment. The paper observes the case of the urban planning process of the Tartu city centre in Estonia during 2010–2016, and is particularly concerned with the roles that urban nature has acquired in the process of this “textualization” of the local environment, societal ideals, practices and possible others.

Multi-agent system (MAS) models have been increasingly applied to the simulation of complex phenomena in different areas, providing successful and credible results. Citizens behavior related to a specific urban activity (i.e., recreation activities in a park, using bicycle for mobility purposes) can be modeled as an agent (actor) with several affinities and preferences which are dependent on aspects that affect the activity. A particular application of a MAS approach is in area of urban policy design, in which policies should be designed considering citizens needs, preferences and behavior. Once an open space in a city is available (i.e., an industry is moved to an industrial area), a land use policy should contribute to identify the new use for the urban space. There are different land use policies that can be applied depending on which services or facilities must be empowered in the city. It is important to identify the correct policy in order to satisfy present citizens needs but considering also the future needs in a social changing context. A socio-technological simulation model has been developed to allow citizens to get a better understanding of the urban problem, its dynamics and explore the sustainability of the different solutions., enhancing citizens to participate in the urban decisions through new technologies (i.e., e-participation). This paper illustrates an open space MAS simulation model for land use design policies in which citizens can check their opinion and get a better understanding of the different choices and its acceptability by the community considering not only present neighborhood profiles, but also future neighborhood configurations. It is the first step before the development of the final software including a user friendly interface to let citizens with different cultural profiles to perform simulations as an essential and neutral tool to reach consensus during the decision-making process in urban policy design.

There have made great progress in urban space research which based on the individual bodily difference in the context of postmodernism. Feminine space also has been focused in the Architecture. In China, women often are regarded as one unit of sub-groups, whose living condition and living space had undergone great changes. Based on the bodily difference, from the view of functional requirements, behavior needs, physical needs and psychological requirements of women, the paper discusses the major existing problems in four aspects, which concluding function layout, transport supply, service facilities and space identify. Combined architecture and geography, sociology, urban planning, the paper uses the method of cognitive map and preference method to explore feminine cognitive pattern and behavior model, thus construct the ideal paradigm of urban feminine public space.

Private Housing

The article is devoted to the specifics of local communities’ self-organization in the “private housing sector” of a Russian provincial city. It is shown that a significant part of the urban space of the Russian territory is made up of low-rise single-family houses, known as the “private housing sector”. The organization of living space and the way of life in such localities can be defined as “non-urban”. It is shown that reciprocity was the basis for the formation of such communities in Soviet times. Having spread as a mechanism for adaptation and survival in the urban environment, reciprocity has become the most important mechanism for securing the marginality (“temporary”) of communities in the “private housing sector”. Changes in the “private housing sector” in the post-Soviet period led to a decrease in the role of reciprocity in the organization of such communities, which in turn led to their fragmentation and the emergence of various variants of local communities. The article is based on the observation, including participant, of the evolution of local spaces and communities of the “private sector” of Irkutsk, Omsk and Khabarovsk during 2007–2019 and a series of interviews from 2016–2020.
