Moped-style scooters are one of the most popular systems of micro-mobility. They are undoubtedly good for the city, as they promote forms of environmentally-friendly mobility, in which flexibility helps prevent traffic build-up in the urban centers where they operate. However, their increasing numbers are also generating conflicts as a result of the bad behavior of users, their unwarranted use in public spaces, and above all their parking. This paper proposes a methodology for finding parking spaces for shared motorcycle services using Geographic information system (GIS) location-allocation models and Global Positioning System (GPS) data. We used the center of Madrid and data from the company Muving (one of the city’s main operators) for our case study. As well as finding the location of parking spaces for motorbikes, our analysis examines how the varying distribution of demand over the course of the day affects the demand allocated to parking spaces. The results demonstrate how reserving a relatively small number of parking spaces for scooters makes it possible to capture over 70% of journeys in the catchment area. The daily variations in the distribution of demand slightly reduce the efficiency of the network of parking spaces in the morning and increase it at night, when demand is strongly focused on the most central areas.

PurposeUrbanization is characterized mainly by changes in land use and conversion of natural areas into built environments, as well as by a series of impacts, such as loss of biodiversity, which interfere with the proper functioning of ecological networks.Design/methodology/approachThus, the authors apply a bibliometric analysis using the term “Urban Trees” in the “Web of Science” database, between 2009 and 2019, as a keyword to include all urban green structures and identify the main aspects of urban ecological relationships. They found 8,367 published articles.FindingsThis review identified the main countries and research institutions that operate in urban afforestation. In general, developing countries seek to understand the environmental benefits that urban afforestation can provide, demonstrating the importance of maintaining existing green areas in urban centers to promote the balance of the ecosystem. It depends directly on the flow of ecosystem services provided by green infrastructures in the city, contributing significantly to carbon sequestration, retention of particulate matter, mitigation of heat islands and reduction of surface runoff, directly favoring the health and well-being of the population. The authors conclude that the actions currently implemented in urban afforestation, especially to increase the richness and abundance of species, will be decisive for the future of urban centers and the construction of more sustainable and egalitarian cities.Originality/valueThis work sought to develop a bibliographic research based on information obtained by bibliometric analysis that has the ability to identify trends and volumes of scientific production in a given area of knowledge.

In the later Middle Ages Brașov was one of the leading urban centers in the Kingdom of Hungary and boasted over a dozen churches and chapels, the most impressive one being the Black Church. Most of the medieval worship sites were still standing in the 18th century, after the Habsburg takeover of Transylvania, but some were subsequently renovated or rebuilt. Additionally, two new churches were erected in 1783 in the northern suburbs. This article has recorded all the worship places depicted by the city plans of Brașov published in 1699, 1702, 1736, 1747 and 1796. The five cartographic documents illustrate nine churches (five Lutheran, two Roman-Catholic and two Orthodox). Besides the churches, three Roman-Catholic chapels are represented by the 1796 city plan and by two local survey plans of the Cetățuie (“Fortress”) area from ca. 1750.

The paper discusses rural transformations resulting from urban influences. The analyzed area consists of rural municipalities (the smallest administrative units in Poland) in the immediate vicinity of Olsztyn, Elblag and Ełk – the largest cities in Warmia and Mazury. The type and rate of social and spatial changes in rural areas with high urban impact were analyzed. The following issues have been addressed: – a comparison between demographic changes in rural municipalities neighboring on urban centres and demographic changes in the city, – changes in the land use structure of rural municipalities neighboring on urban centers, with particular emphasis on open and protected spaces, – architectural changes in the analyzed suburban areas, – landscape changes in the analyzed suburban areas.

High Infiltration

The process of urbanization interferes in the elements of the hydrological cycle, altering the infiltration, flow, and evaporation of rainwater. Several methods and tests exist for analyzing this hydrological cycle that aim to hydrodynamically characterize the soil of a locality. However, the collection and field trials can be expensive and time consuming. Because of these high costs, it is important to look for methods that save time and money. One such method is to perform simulations of water flow in the soil, using computational models such as Hydrus 1-D, in order to explain the water balance of a region. The results of these simulations showed that 355.18 mm.m-2 of the total 385.02 mm.m-2 of precipitation was able to infiltrate, indicating that the soil of the region has a high infiltration capacity, due to its high sand content. However, of the 228,000 m2 studied, only 38,760 m2 are unpaved soil. This shows that the soil at the location studied would be able to infiltrate most rainwater without the occurrence of flooding, if more than only 17% of the land area were permeable soil. This conclusion can be extrapolated to other areas surrounding this neighborhood and to other large urban centers, which have similar characteristics.

Linear Cluster

Modern cities with tall building clusters can create powerful and distinctive features on the skyline more so than those with scattered tall buildings. In terms of their role in the city, tall building clusters can improve the image of the city, provide for high population density, and distinguish the urban centers. However, the planning of tall building clusters needs to be conducted using in-depth analysis in response to the spatial context to create an attractive skyline. This research attempts to compare different layouts of tall building clusters organized in circular, rectangular, and linear geographical areas. Their impact on the skyline was determined by analyzing the visibility and height transitions of these tall building clusters. Grasshopper was used to calculate the degree of surface visibility of these tall buildings from observers in urban spaces. To quantify the height transition of the cluster, the obstructed buildings were identified and mapped on the skyline viewed from a specific viewpoint. The results showed that the linear cluster had high visibility, followed by the circular and rectangular clusters. Decreasing the heights from the center to the periphery supported the focal point of the cluster.

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.

AbstractThis article examines the relationship between urbanization and women's empowerment through the Turkish case. The article first tests statistically the overall impact of urbanization on women's empowerment by tapping into educational, economic, and political indicators at the province level. The results yield a positive relationship between urbanization and women's empowerment. We argue that these empowerment indicators demonstrate the necessary conditions of women's empowerment, yet whether these are sufficient for women to feel empowered needs to be further tested. To do so, the article utilizes an extensive original survey of 334 well-educated urban women in 43 out of 81 provinces of Turkey to examine the extent to which the results found in the quantitative section are paralleled by the actual experiences of women. The survey analysis reveals prospects and obstacles that well-educated women face in old and new urban centers. This nonrandom, purposive sample of seemingly empowered urban women shows that the barriers faced by these women would easily multiply when lower strata of society are reached. The Turkish case demonstrates that societal transformations such as urbanization have an imprint on the fates of women, yet further women's empowerment needs collective action at the political, legal, and societal levels.
