Analysis of urban complex networks

Abstract

We analyze the dual graph representation of urban textures by the methods of complex network theory and spectral graph theory. We present the empirical diagrams of distributions of the nearest and far-away neighbors in the several European compact urban patterns and the spectra of normalized Laplace operator defined on their dual graphs.

Influence of the Global Urban Grid on Natural Movement within a Local Public Space

“…The principle of space syntax supports the belief that spatial patterns or structures could help forecast the impact of space properties on social activities, such as pedestrian and vehicular movement patterns, in urban environments (Hillier, 2007;Mohammed, 2011;Volchenkov, 2008). The forecasting accuracy has been found to range from 60-80% based on moving potentials and observed movement rates (Hillier and Sahbaz, 2009).…”

Comparative Analysis of Traffic Performance of Urban Transportation Systems

“…A review of the literature on the subject of this study reveals a range of prior relevant research work, differing in their selected network structures, performance measures, their applications, and analysis methodologies (Polzin, 2004;Stead and Marshall, 2001). Several studies have focused on defining proper quantitative traffic performance measures for capturing the impacts Page 5 of 27 of different transportation network structures (Buhl et al, 2006;Hu et al, 2008;Naga and Fan, 2007;National Research Council (U.S.) et al, 2010;Volchenkov, 2008;Xie and Levinson, 2007). Some other works have looked at the problem from a planning perspective, in which the interaction between the structure and spread of the network with travel parameters such as trip frequency and mode of travel have been studied (Jiang, 2007;Levinson, 2012;Rui et al, 2013;Yang et al, 2010;Zhang and Levinson, 2004).…”
