This paper examines the relationship between street centrality and densities of commercial service activities in city Bologna, northern Italy. Street is calibrated a multiple assessment model composed measures such as closeness, betweenness, straightness. Kernel density estimation used to transform datasets one scale unit for analysis correlation them. Results indicate that retail Bologna tend concentrate areas with better centralities. The distribution these correlates highly global...
Urbanisation is a fundamental phenomenon whose quantitative characterisation still inadequate. We report here the empirical analysis of unique data set regarding almost 200 years evolution road network in large area located north Milan (Italy). find that urbanisation characterised by homogenisation cell shapes, and stability throughout time high-centrality roads which constitute backbone urban structure, confirming importance historical paths. show quantitatively growth governed two...
Abstract Human settlements are the cause and consequence of most environmental societal changes on Earth; however, their location extent is still under debate. We provide here a new 10 m resolution (0.32 arc sec) global map human Earth for year 2015, namely World Settlement Footprint 2015 (WSF2015). The raster dataset has been generated by means an advanced classification system which, first time, jointly exploits open-and-free optical radar satellite imagery. WSF2015 validated against...
The paper examines the geography of three street centrality indices and their correlations with various types economic activities in Barcelona, Spain. focus is on what type (closeness, betweenness straightness) more closely associated which activity (primary secondary). Centralities are calculated purely network by using a multiple assessment model, kernel density estimation method applied to both centralities permit correlation analysis between them. Results indicate that correlated...
Bicycle sharing systems exist in hundreds of cities around the world, with aim providing a form public transport associated health and environmental benefits cycling without burden private ownership maintenance. Five have provided research data on journeys (start end time location) taking place their bicycle system. In this paper, we employ visualization, descriptive statistics spatial network analysis tools to explore system usage these cities, using techniques investigate features specific...
We compare the structural properties of street networks ten different European cities using their primal representation. investigate geometry and a set centrality measures highlighting differences similarities between cases. In particular, we found that share due to quasiplanarity but there are also several distinctive geometrical properties. A principal component analysis is performed on distributions centralities respective moments, which used find characteristics by can classify into...
Most large cities are spanned by more than one transportation system. These different modes of transport have usually been studied separately: it is however important to understand the impact on urban systems coupling and we report in this paper an empirical analysis between street network subway for two metropolitan areas London New York. We observe a similar behaviour quantities related quickest paths suggesting existence generic mechanisms operating beyond local peculiarities specific...
The modern discipline of urban morphology gives us a ground for the comparative analysis cities, which increasingly includes specific quantitative elements. In this paper, we make further step forward towards definition general method classification form. We draw from morphometrics and taxonomy in life sciences to propose such method, name ‘urban morphometrics’. then test it on unit landscape named ‘Sanctuary Area’ (SA), explored 45 cities whose origins span four historic time periods:...
Recent advances in the urban science make broad use of notion scaling. We focus here on important scaling relationship between gross metropolitan product (GMP) a city and its population (pop). It has been demonstrated that GMP $\propto$ Y pop $^{\beta}$ with $\beta$ always greater than 1 close to 1.2. This fundamental finding highlights universal rule holds across countries cultures might explain very nature cities. However, an increasingly connected world, hypothesis economy solely depends...
Shortest paths are not always simple. In planar networks, they can be very different from those with the smallest number of turns - simplest paths. The statistical comparison lengths shortest and provides a non trivial local information about spatial organization these graphs. We define simplicity index as average ratio profile characterizes at scales. measure metrics on artificial (roads, highways, railways) natural networks (leaves, slime mould, insect wings) show that there fundamental...
Because of increasing global urbanization and its immediate consequences, including changes in patterns food demand, circulation land use, the next century will witness a major increase extent paved roads built worldwide. To model effects this increase, it is crucial to understand whether possible self-organized are inherent road network structure. Here, we use largest updated database comprising all on Earth, together with urban cropland inventories, suggest that length distributions within...
Human mobility is increasing in its volume, speed and reach, leading to the movement introduction of pathogens through infected travelers. An understanding how areas are connected, strength these connections this translates into disease spread valuable for planning surveillance designing control elimination strategies. While analyses have been undertaken identify map connectivity global air, shipping migration networks, such yet be on road networks that carry vast majority travellers low...
In this study we propose a new method to simulate hyper-realistic urban patterns using Generative Adversarial Networks trained with global land-use inventory. We generated synthetic "universe" that qualitatively reproduces the complex spatial organization observed in patterns, while being able quantitatively recover certain key high-level metrics.
We report an analysis of the accessibility between different locations in big cities, which is illustrated with respect to London and Paris. The effects respective underground systems facilitating more uniform access diverse places are also quantified investigated. It shown that Paris have markedly patterns accessibility, as a consequence number bridges large parks London, both cases imply general, thought distinct manners, increase accessibility.
Abstract Human settlements on Earth are scattered in a multitude of shapes, sizes and spatial arrangements. These patterns often not random but result complex geographical, cultural, economic historical processes that have profound human ecological impacts. However, little is known about the global distribution these forces creates them. This study analyses from high-resolution satellite imagery provides classification patterns. We find two emerging classes, namely agglomeration dispersion....
We analyse the results of our experimental laboratory approximation motorway networks with slime mould Physarum polycephalum. Motorway 14 geographical areas are considered: Australia, Africa, Belgium, Brazil, Canada, China, Germany, Iberia, Italy, Malaysia, Mexico, Netherlands, UK and USA. For each entity, we represented major urban by oat flakes inoculated in a capital. After spanned all network its protoplasmic tubes, extracted generalised graph from compared graphs an abstract using most...
The availability of mobility data is increasing thanks to the widespread adoption mobile phones and location-based services.This generates powerful insights on people's habits, with applications in areas such as health, migration, poverty estimation.Yet despite growing academic literature usage application phone location this field raising awareness importance disaster preparedness response climate change resilience, large-scale remain under-utilized real-world management operations date...
In previous research we defined a methodology for mapping centrality in urban networks. Such methodology, named Multiple Centrality Assessment (MCA), makes it possible to ascertain how each street is structurally central city according several different notions of centrality, as well scales "being central". this study investigate the case Bologna, northern Italy, about much higher statistically "determines" presence activities (shops and services). Our work develops based on kernel density...
Urbanization plays a crucial role in the economic development of every country. The mutual relationship between urbanization any country and its productive structure is far from being understood. We analyzed historical evolution product exports for all countries using World Trade Web (WTW) with respect to patterns 1995-2010. Using evolving framework complexity, we reveal that country's terms production export goods, interwoven process during early stages growth. Meanwhile urbanized...
