The Signature of Organic Urban Growth

  title={The Signature of Organic Urban Growth},
  author={Leonard Carl Staffan Nilsson and Jorge Gil},
  journal={The Mathematics of Urban Morphology},
Cities are complex, perhaps one of the most complex kinds of structure created by humans. Some cities have been planned to a large extent while others have grown organically. The outcome of planning and growth processes is the diverse morphological built form and street patterns observed in cities today. So far, in urban planning and history research, cities are classified as planned or organic, largely based on the visual assessment of their urban morphology. To understand cities and their… 
Towards analytical typologies of plot systems: Quantitative profile of five European cities
The aim of the paper is to introduce a classification of plot systems into typologies based on five European cities, in order to distinguish particular spatial differences and similarities in terms of their plot structure.
Understanding Chinese Urban Form: The Universal Fractal Pattern of Street Networks over 298 Cities
The results show that almost all cities bear a fractal structure in terms of street connectivities, and the multiple regression analysis suggests that the fractality of street networks is positively correlated with urban socioeconomic status and negatively correlated with energy consumption.
Urban spatial order: street network orientation, configuration, and entropy
This study examines street network orientation, configuration, and entropy in 100 cities around the world using OpenStreetMap data and OSMnx and develops a new indicator of orientation-order that quantifies how a city’s street network follows the geometric ordering logic of a single grid.

It is concluded that that the priorities in city planning affect the efficiency of transportation and the Efficiency of the network can be assessed by a simple yet effective procedure based on circuity to guide policymaking.
Street Network Resilience Put to the Test: The Dramatic Crash of Genoa and Bologna Bridges
This paper proposes and testing, in a real-life scenario, a method for the computational analysis of street network resilience, based on Space Syntax theory, and presents a set of configurational resilience indices, whose reliability is qualitatively assessed considering the ex-ante and ex-post urban configurations generated by two exceptional and dramatic bridge crashes.
Visualization, Spatiotemporal Patterns, and Directional Analysis of Urban Activities Using Geolocation Data Extracted from LBSN
LBSN can be considered as a supplementary and reliable source of social media big data for observing urban activities and behavior within a city in space and time and show that women were more inclined to use social media compared with men.
Analyzing the Check-In Behavior of Visitors through Machine Learning Model by Mining Social Network's Big Data
Assessing and comparing the seasonal check-in behavior of individuals in Shanghai, China, using location-based social network (LBSN) data and a variety of spatiotemporal analytic techniques demonstrates that visitors' spatial operations are more intense than resident's spatial operations, notably in downtown.


Urban Scaling and Its Deviations: Revealing the Structure of Wealth, Innovation and Crime across Cities
It is found that local urban dynamics display long-term memory, so cities under or outperforming their size expectation maintain such (dis)advantage for decades.
The New Science of Cities
In The New Science of Cities, Michael Batty suggests that to understand cities we must view them not simply as places in space but as systems of networks and flows. To understand space, he argues, we
On the discovery of urban typologies: Data mining the many dimensions of urban form
This paper presents a method to support the description and prescription of urban form that is context- sensitive, multi-dimensional, systematic, exploratory, and quantitative, thus facilitating the application of urban typomorphology to planning practice.
A typology of street patterns
It is shown with the example of New York and its different boroughs, that the fingerprint of a city can be seen as the sum of the ones characterizing the different neighbourhoods inside a city.
A Service Classification of American Cities
E VERYONE is aware that modern cities are performing more and more of the services necessary to the functioning of society. There is an awareness, too, that these vital services are not performed in
Centrality in networks of urban streets.
A comprehensive study of centrality distributions over geographic networks of urban streets indicates that a spatial analysis, that is grounded not on a single centrality assessment but on a set of different centrality indices, allows an extended comprehension of the city structure.
Allometry in the Syntax of Street Networks: Evolution of Adriatic and Ionian Coastal Cities 1800–2010
Urban growth is discussed according to the impact of size on metric and topological space syntax measures that describe street networks. The quantitative analysis of three historical stages of cities
Space is the machine: A configurational theory of architecture
The aim of this book is to assemble some of this work on configurational ideas in bringing to light the spatial logic of buildings and cities and show how it leads the way to a new type of theory of architecture: ananalytic theory in which understanding and design advance together.
