Sustainable urban development is a new concept of fundamental environmental metropolitan management that not only creates the demand for changing the concepts of economic development, but also affects social development. The current study provides a conceptual model of a sustainable environment pattern In District 22 of Tehran that depends on the relationship between environment and economy, ...
Transportation and its environmental impacts are a major component of urban environmental management. At the same time, transportation and mobility are an important part or urban economics and the quality of life. To analyse urban transportation and its environmental impacts, a comprehensive, interdisciplinary approach is needed. No single model can cover the range of spatial and temporal scale...
OCTOBER 2004 AMERICAN METEOROLOGICAL SOCIETY | A erosols are airborne suspensions of tiny particles, each typically about one-thousandth the diameter of the period at the end of this sentence. Cumulatively, they have profound effects at a variety of scales, exerting myriad influences on the earth’s environment and climate and on human health. Many aerosols originate from natural sources—volcano...

This research analyses the suburban expansion in the metropolitan area of Tehran, Iran. A hybrid model consisting of logistic regression model, Markov chain (MC), and cellular automata (CA) was designed to improve the performance of the standard logistic regression model. Environmental and socio-economic variables dealing with urban sprawl were operationalised to create a probability surface of...
The paper reviews the relationship between spatial and transportation planning in the Southern African Development Community (SADC) region of Sub-Saharan Africa. It argues that most urbanisation in the region has largely occurred subsequent to the 1950s and, accordingly, urban development has been profoundly and negatively affected by the (misguided) spatial and institutional tenets of modernis...
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...
the rapid change of land use and land cover in the metropolitan area of tehran has influenced the distribution pattern of land surface temperature (lst). in this study, a spatial autocorrelation analysis is adopted to process the spatial-temporal changes of lst and normalized difference vegetation index (ndvi) in tehran during the period of 1987 to 2010. global spatial autocorrelation analysis ...
T he problems of urban sprawl-low-density residential and commercial development, road traffic congestion and high cost public transit systems are the result of the cumulative, long-term effect of disjointed planning decisions on the urban fabric. What is needed to offset the planning mistakes of the last 30 years is an integrated approach to land use and transportation planning. Existing plann...
