With the rapid development of society, the traffic problem has become increasingly severe, and the traditional methods can no longer effectively solve the current social traffic behaviour problems. Although studies on the dynamics of human traffic behaviour based on traffic modes can effectively reveal the anomalies in traffic behaviour, few studies integrate intelligent traffic behaviour with multiple traffic modes. Based on the numerous traffic data of bike-sharing and ride-hailing in a Chinese city, this paper reveals the dynamic characteristics of various traffic behaviours in the city by combining spatiotemporal characteristics index and urban spatial structure with human traffic behaviour patterns. The experimental results show that the traffic behaviour of the town presents a double logarithmic power-law distribution in time characteristics, and there is a close interdependent dynamic relationship with the city’s spatial structure. The research in this paper can reveal the relationship between bimodal power-law distribution and spatial characteristics in complex systems and help solve social traffic problems effectively in social reality. Further research results can provide practical planning guidance for the behavioural integration of multiple traffic in smart cities.

In recent years, with the rapid development of VR technology, its application range gradually involves the field of urban landscape design. VR technology can simulate complex environments, breaking through the limitations of traditional environmental design on large amounts of information processing and rendering of renderings. It can display complex and abstract urban environmental design through visualization. With the support of high-speed information transmission in the 5G era, VR technology can simulate the overall urban landscape design by generating VR panoramas, and it can also bring the experiencer into an immersive and interactive virtual reality world through VR video Experience. Based on this, this article uses the 5G virtual reality method in the new media urban landscape design to conduct research, aiming to provide an urban landscape design method with strong authenticity, good user experience and vividness. This paper studies the urban landscape design method in the new media environment; in addition, how to realize the VR panorama in the 5G environment, and also explores the image design of each node in the city in detail; and uses the park design in the city As an example, the realization process of the entire virtual reality is described in detail. The research in this article shows that the new media urban landscape design method based on 5G virtual reality, specifically to the design of urban roads, water divisions, street landscapes, and people’s living environment, makes the realization of smart cities possible.

The study of physical and social divisions in divided societies has long been an area of study, such as the continued usage of 'peace walls' in Belfast, hostile architecture to prevent anti-social behaviour and rough sleeping, and the securitisation of private spaces. In the context of a new drive to create a smart district, this paper looks at the relationship between smart urbanism and planning, and at the spatial and social divisions between a new 'gentrifying' and well-educated community in the Dublin Docklands and established communities in the area. The Dublin Docklands redevelopment marks a significant break from a pattern of suburbanisation and inner-city decline and repurposes part of the former port area as a city centre extension. The paper accounts for the reshaping of the Dublin Docklands as a ‘smart district’ in collaboration with the city authorities, based on over thirty semi-structured interviews and participant-observation at consultation events. It argues that reductive definitions of smart cities as networking technologies be reworked into broader considerations on urban technologies and the future of cities, with greater emphasis on the relationship between technologies branded as ‘smart’ and the material and digital manifestation of boundaries in urban form.

This article first provides a critical scoping review of empirical literature on the relationship between urban structure and travel in China. The review finds that residential suburbanization alone increases travel, polycentric development has mixed effects, and jobs–housing balance reduces travel. Second, this article compares the empirical findings of the urban structure–travel relationships in China with those observed in other countries, and it identifies contextual factors that can explain the differing relationships in China. We suggest that future research improve data and methodology and broaden the research scope to investigate the complex mechanisms that affect the urban structure–travel relationship in China.

This paper aims to investigate the approach of density policies in the Tehran Master Plan and the consequences of ignoring the macro spatial scale in density policymaking. In this study, the floor area ratio (FAR) regulations of the Master Plan of Tehran (which are defined by specific land use zones) are used as one of the main densification tools. Then, employing the Getis–Ord Local G and geographic weighted regression (GWR) statistical tests, Arc GIS 10.3 software, and population and employment variables, the spatial outcomes of the Master Plan density policies were modeled. In this research, both population and employment (job) variables and their relationship were utilized to depict the urban spatial structure of the city. The model will show the resulting spatial structure of Tehran if the densification policies of the plan are realized. The findings of the research are surprising, as they indicate that the Master Plan’s densification policies would worsen the current spatial structure by disrupting the current population and employment spatial structure and neglecting their logical relationships. In fact, the Master Plan would change the current polycentric structure into a highly dispersed structure due to its densification approach, which is mainly based on the neighborhood micro scale.

Data mining and simulation of the Internet of things (IOT) have been applied more and more widely in the rapidly developing urban research discipline. Urban spatial structure is an important field that needs to be explored in the sustainable urban development, while data mining is relatively rare in the research of urban spatial structure. In this study, 705,747 POI (Point of Interest) were used to conduct simulation analysis of western cities in China by mining the data of online maps. Through kernel density analysis and spatial correlation index, the distribution and aggregation characteristics of different types of POI data in urban space were analyzed and the spatial analysis and correlation characteristics among different functional centers of the city were obtained. The spatial structure of the city is characterized by “multicenters and multigroups”, and the distribution of multicenters is also shown in cities with different functional types. The development degree of different urban centers varies significantly, but most of them are still in their infancy. Data mining of Internet of things (IOT) has good adaptability in city simulation and will play an important role in urban research in the future.

<p>City is a space that serves as a center place of activities, over time the city was experiencing growth and development, both physical and non-physical conditions. So these conditions affect the change in the pattern of land use, activity system as well as the pattern of people and goods mobility that are happening in the urban system. The phenomenon of the emergence of new urban areas (cities and towns) in IKK Gemolong causes changes in land use patterns along the road corridor is experiencing rapid development, it is evidenced by the increased activity and physical growth of the city. The conditions were observed with the growth of new activities such as residential, commercial district and other commercial areas. So that it will affect land use patterns, activities systems and people and goods mobility patterns that occur, which in turn will affect the characteristics of the spatial structure of the development of IKK Gemolong formed as a town in Sragen. The focus of discussion such as land use, population activity systems, as well as the people and goods mobility which the influencing factors of the formation of the spatial structure of a city. The study is considered important because as the basis for consideration in the development of towns in the future. This is because the policy of urban development continues in administrative and sectoral nature, so the presence of the regional autonomy policy of development with regional and integrated system and assessed more quickly to implement. This study used quantitative an quantitative study method. The analysis results indicated the characteristics of land use in Gemolong dominated by settlements, while the commercial district developed along the main streets of this town because Gemolong have function as service centers for its surrounding areas. The residents of Gemolong mostly have work in the non-agricultural sectors, such as trade and services, while the population as a farmer is relatively small, so that these conditions indicated that Gemolong says as urban area. The people mobility in Gemolong originated from both internal and external area of the town in destination location of commercial areas to have studying, working, shopping and other purposes. The residents of Gemolong do not have to big cities to access the daily life necessities for since it is already available in Gemolong. Based on the phenomenon of Gemolong have a compact city type of development, while the structure of urban spaces that were formed have view more functioning of each of the regions even though the condition is still occurring mixture of functions. Then, the structure of urban spaces is the type of sector, although not as ideal as yet which happened in developed countries.</p>

The article reveals regularities between the spatial structure of the city-temple-icons and the similar structural principle, which, in the context of Hesychast anthropology, acts in the topography of the human soul. The spatial structure of the Tree of Life, a universal symbol contained in the topographical icons of the level and of the city, temple, icon, and human, is developed and proposed. It is proved that the spatial framework of the Tree of Life is the Golgotha ​​Cross. Considerable attention is paid to the analysis of the main spatial zones of the temple-icons, which have a hierarchical construction. It is assumed that the topographical icon of the city-temple-icon-human is arranged in such a way that it is possible to overcome the ontological gap that was created as a result of original sin. Particularly with the help of distinct geometric constants that determine the structure of the Tree of Life, ancient iconographs tried to restrain/seal the gaping hole, which seemed to be an insurmountable Rubicon, at the moment of the fall between the Spirit and the soul, the mind and heart of man, earthly and divine, profane and sacred worlds. Consequently, the use of sacred numbers was deliberately incorporated into sacred texts, icons, and in the architecture and iconographic programs of the temples. It was analyzed that the internal structure/main sacral energy framework of the icon-temple contains compositional nodes associated with the disclosure of the main semantic load in the iconographic program/plot, and are always constructed on the lines of the golden section. Some regularities in the placement of the central figure in the composition of the temple icon are traced. In the temple, as in the icon, the semantic center of the sacred space is the image of Christ the Almighty, who is placed in a top of an equilateral triangle with a side size corresponding to the width of the temple. The center of the Nimbus passes through the golden section. In the context of the relationship between the topography of the icon-temple and the proposed scheme for determining the topography of the human soul. According to the analogy principle, the structural-spatial scheme of the Tree of Life in the anthropological aspect is associated with the stages of the spiritual perfection of the human soul.

Dockless bike sharing provides a convenient and affordable means of transport for urban residents. It solves the “last-mile problem” in public transport by reducing the travel cost between home and subway stations and thus increasing the attractiveness of distant apartments. This may affect the relationship between housing price and distance to subway and reduce the price premium enjoyed by proximate apartments. Using resale apartment data in 10 major cities in China, a difference-in-differences approach at the apartment level, and a two-step estimator at the city-month level, we find that the entry of bike sharing reduces the housing price premium by 29% per km away from a subway station. The effect is equivalent to a reduction of 1,893–2,127 CNY (282–317 USD) in commuting costs per household per annum over 30 years. The effect is driven by a relative increase in the listing price of, and in the demand for, apartments distant from vis-à-vis proximate to subway stations.
