The relationship between vegetation, transportation networks, and crime has been under debate. Vegetation has been positively correlated with fear of crime; however, the actual correlation between vegetation and occurrences of crime is uncertain. Transportation networks have also been connected with crime occurrence but their impact on crime tends to vary over different circumstances. By conduc...

A city and its transportation network are both complicated systems. Fractal geometry provides an effective way to describe the complex property of geographical features. This paper uses a modified box-counting method to describe the fractal property of urban transportation networks. Assuming that human settlements of different sizes are all operated by the same growth procedure, this paper inve...

since the 1990’s, network reliability has been considered as a new index for evaluating transportation networks under uncertainty. a large number of studies have been revealed in the literature in this field, which are mostly dedicated to developing relevant measures that can be utilized for the evaluation of vulnerable networks under different sources of uncertainty, such as daily traffic flow...

— In today’s world, wireless mobile communications devices are creating new dimensions of interconnectedness between people, places, and urban infrastructure. This ubiquitous connectivity within the environment can be observed and interpreted in real-time through aggregate records collected from communication and transportation networks. The real-time acquisition can regard traces of informatio...

We consider the dynamics between population and spatial distribution networks for the 200 largest urban agglomerations. Population dynamics are considered from 1950 to 2010 and distribution networks are analyzed in terms of vehicular transportation infrastructure. We observe that the growth of large urban agglomerations, in terms of population density, has slowed down in the second half of the ...

Intelligent Transportation System (ITS) is one of the most important urban systems that its functionality affects other urban systems directly and indirectly. In developing societies, increasing the transportation system efficiency is an important concern, because variety of problems such as heavy traffic condition, rise of the accident rate and the reduced performance happen with the rise of p...
