This paper aims to characterize urban street networks from the perspective of facility location that is widely used for siting public or private services. Both topological and geometrical features of urban street networks are investigated to examine their impacts on the performance of facility location. We propose a set of efficiency and centrality measures to evaluate the amenability of street networks for locating facilities. The evaluation of 15 large cities in the U.S. reveals that facility locations are strongly affected by road network structures. For realistic street networks, grid planned road network are more amenable to locating facilities than irregular networks. The analyses on idealized network offer further evidence of the correlations between network properties and service provision efficiencies.read more

Walking accessibility for individuals with reduced mobility: a Brazilian case study
TL;DR: Two methods of evaluation were used: the Analytic Hierarchy Process (AHP), to consider the multiple criteria that define a quantitative index of the pedestrian accessibility; and the Commented Paths Method (Methode des Parcours Commentes) for a qualitative analysis of the practical subjective experience.

Identifying Urban Inconsistencies via Street Networks
TL;DR: This work devised algorithms capable of preprocessing and analyzing street networks, pointing to existing mobility problems in a city, and identifies inconsistencies that pertain to a given node where a facility of interest is currently placed.

A Spatial Fuzzy Multicriteria Analysis of Accessibility: A Case Study in Brazil
TL;DR: In this article, the authors present an accessibility evaluation model that applies multiple attributes, fuzzy functions, and spatial analysis tools to determine indices that reflect an average level of attractiveness for each potential destination (deemed a location of interest), each destination has different weights based on its degree of importance.

Collective dynamics of small-world networks
TL;DR: Simple models of networks that can be tuned through this middle ground: regular networks ‘rewired’ to introduce increasing amounts of disorder are explored, finding that these systems can be highly clustered, like regular lattices, yet have small characteristic path lengths, like random graphs.

Efficient Behavior of Small-World Networks
TL;DR: It is shown that the underlying general principle of their construction is in fact a small-world principle of high efficiency, which gives a clear physical meaning to the concept of "small world," and also a precise quantitative analysis of both weighted and unweighted networks.

Optimum Locations of Switching Centers and the Absolute Centers and Medians of a Graph
TL;DR: It is shown that the optimum location of a switching center is always at a vertex of the communication network while the best location for the police station is not necessarily at an intersection.

The Origins of Scaling in Cities
TL;DR: All cities may evolve according to a small set of basic principles that operate locally, which are shown to be independent of city size and might be a useful means to evaluate urban planning strategies.

The network analysis of urban streets: A dual approach
TL;DR: The authors show that the absence of any clue of assortativity differentiates urban street networks from other non-geographic systems and that most of the considered networks have a broad degree distribution typical of scale-free networks and exhibit small-world properties as well.
