one of the most important subjects in 21 century in relation to sustainable urban development is urban form. urban form that is pattern of spatial distribution of human activities in a specific period can be divided into two kinds: compact city and urban sprawl. because there is a close relation between urban form and urban sustainability, urban planners have to know about urban pattern and for...

Patterns of land use and available transportation systems play a critical role in determining the economic vitality, livability, and sustainability of urban areas. Transportation interacts strongly with land use. For example, automobile-oriented development induces demand for more roads and parking (which in turn induces more automobile-oriented development), while compact, pedestrian-friendly ...

A hybrid life cycle-based trans-boundary greenhouse gas (GHG) emissions footprint is elucidated at the city-scale and evaluated for 8 US cities. The method incorporates end-uses of energy within city boundaries, plus cross-boundary demand for airline/freight transport and embodied energy of four key urban materials [food, water, energy (fuels), and shelter (cement)], essential for life in all c...

This paper examines the relationship between growth and poverty in Iran during the first five-year plan. In other words, effort has been made to show whether economic growth in Iran helped poor people or not. For this purpose the concept of pro poor growth has been analyzed with application to the economy of Iran, both in urban and rural areas and in the country as a whole. We use an indicator ...

In this paper we study a two-phase free boundary problem for a semilinear elliptic equation on a bounded domain $Dsubset mathbb{R}^{n}$ with smooth boundary‎. ‎We give some results on the growth of solutions and characterize the free boundary points in terms of homogeneous harmonic polynomials using a fundamental result of Caffarelli and Friedman regarding the representation of functions whose ...

in the urban history of iran, “mashroote” era (the constitutional revolution) is considered as a turning point. in this period, the government had an organized and purposeful interference in the urban development of the country. another organized interference of the government, happened in 1960s. the effects of these movements were very significant in the growth of urban patterns and in the urb...

Managing and modelling urban growth is a multi-faceted problem. Cities are now recognised as complex systems through which non-linear and dynamic processes, emergence and self-organisation occur. The design of a system that can handle these complexities is a challenging prospect. This paper presents an urban planning tool for the city of Riyadh, Saudi Arabia. At the core of the system is a Fuzz...
