African cities face immense challenges over the coming decades. As countries urbanize, African cities must maintain service provision for rapidly increasing populations, yet with limited resources. In particular, urban food systems must be able to cope with regional food shortages and catalyze (or at least enable) the distribution of food from diverse sources in order to ensure that the cost of...

Axial lines are defined as the longest visibility lines for representing individual linear spaces in urban environments. The least number of axial lines that cover the free space of an urban environment or the space between buildings constitute what is often called an axial map. This is a fundamental tool in space syntax, a theory developed by Bill Hillier and his colleagues for characterizing ...

The automatic process for texturing 3D urban environments realistically is a challenging topic in Computer Graphics, especially when the model is generated from 2D GIS data from real sites. In order to achieve realistic scenes, buildings, urban furniture and street roadways should be modeled automatically also considering the slope of steep streets. A texturing process by hand which takes into ...

The problem of efficient traffic coordination in urban street networks is carefully studied in the paper. The problem description was simplified as much as possible, by defining minimal set of decision variables and deriving necessary constraints on their values. The structure of feasible solutions is established introducing new basis of street network loops. The software package was worked out...

A ray tracing model based on the application of the uniform theory of diffraction (UTD) and geometrical optics (GO) for modeling the propagation in the microcellular urban scenarios has been implemented. This model has been used to analyze the behavior of the rms delay spread while turning a corner in two street-corner environmentsregular and chaflane street corners. The study of the environmen...

Urban climate is strongly influenced by the processes of urban work and life. Expansion of cities and consequently increased human constructions causes to changes in urban climate. The rising temperature of cities rather than the surroundings is one of the effects linked to direct human intervention. Building heating, air pollution and the use of inappropriate materials in the flooring streets...

We present a four-stage meta-heuristic for routing vehicles in an urban environment, with the goal of traversing every street. While the theoretical aspects of street traversal are well-studied, our algorithm is designed to accommodate several obstacles to practical street traversal that are known to be NP-hard, such as turning penalties, the usage of multiple vehicles, and the presence of onew...

This article was written with the aim of the pedestrian impact on increasing social interactions in urban spaces of Bojnourd, with emphasis on social dimensions of social interaction. The method of this research is descriptive-analytic, which first of all has been designed to identify theoretical perspectives, general criteria of environmental quality and then collect field data and interviews ...

Street-parking vehicles cause many problems in urban traffic situation: blinds area, traffic congestions, and so on. Detection method of street-parking vehicles are proposed. The proposed method is based on epipolar-plane image (EPI) analysis. First, our proposed method detects edges in EPIs by applying Hough transformation. By computing depth variation from slope of detected edges, street-park...
