Many complex networks erase parts of their geometry as they develop, so that their evolution is difficult to quantify and trace. Here we introduce entropy measures for quantifying the complexity of street orientations and length variations within planar ne ...
Research on congestion and propagation in large urban city networks has been mainly based on microsimulations of link-level traffic dynamics. However, both the unpredictability of travel behaviors and high complexity of accurate physical modeling remain ch ...
Street networks can be visualized in various ways depending on the purpose. Here we introduce (in the present context) a new technique for visualizing the orientation of street networks in relation to complex topography. The technique is tested on the city ...
In addition to socio-economic factors, major landforms may affect the city structure and urban form. Here we show that landforms have significant effects on the city shape and street patterns of the fast-growing Iranian cities of Dezful (a river) and Khorr ...
Underground space provides an opportunity to increase city compactness and pedestrian accessibility through the overlapping of activities in urban areas. The potential for development is not homogeneous throughout an urban area but depends on variations in ...
Since 2000, declarations issued in rapid succession by the international community have aimed at setting goals to drastically improve the living conditions of slum dwellers while, in the same time, the slums dwellers increased by 4,5% per year in Africa. S ...
We compare the structural properties of the street networks of ten different European cities using their primal representation. We investigate the properties of the geometry of the networks and a set of centrality measures highlighting differences and simi ...
With an approach between theatre, urban analysis, mapping and deconstruction, this 'glide' through Brasilia is an attempt to understand its urban tissue, formed through architectural action and spontaneous appropriation. In the city laid out between a mode ...
We propose a methodology for identifying queue spillovers in city street networks with signalized intersections using data from conventional surveillance systems, such as counts and occupancy from loop detectors. The key idea of the proposed methodology is ...
The city planning of La Chaux-de-Fonds, they way we know it today, is the result of a long evolution. It starts the day after a fire which, in 1794, practically devastated the whole village. With the human and material loss which the fire caused, this disa ...
