during the recent decades, rapid urbanization growth has led to even faster growth of motorvehicles and especially in large cities. hence, evaluation of the actual level of traffic emissions has gained more interest. this paper, for the first time, presents a bottom-up approach for evaluation of vehicular emissions in tehran- the capital of iran- using the international vehicle emission (ive) m...

To combat the environmental problems and congestion which arise from urban transportation, both end-of-pipe interventions such as traffic management and tailpipe emission control and more upstream measures such as urban and land-use planning have been implemented in many cities around the world. Singapore, in particular, has achieved rare success in managing congestion and the environment amid ...

UrbanSim is a new urban simulation model, developed over the past several years, which is now operational in three urban areas in the United States. The model system is designed to address emerging needs to better coordinate transportation and land use planning as a result of recognition of the strong interactions between land use and transportation, increasing pressure from federal transportat...

A spatial analysis of a large 20th century urban settlement (town/city) easily presents the celebrated central Business District (CBD). Theories of Urban Land Economics have easily justified and attempted to explain the existence of such a district activity area within the cityscape. This work examines the gradual emergence and development of the CBD in Lafia Town, Nigeria over 20 years and the...

logistic regression (lr) was used to model urban growth between the years 1987 and 2001 in gorgan city, north east of iran. three groups of variables including economic-social, land use and biophysical variables were used in the modeling practice. using covariance of the independent variables, distance to administrative and sporting centers plus distance to cities were removed. roc (relative op...

In recent years, the concepts of teleconnections and telecoupling have been introduced into land-use and land-cover change literature as frameworks that seek to explain connections between areas that are not in close physical proximity to each other. The conceptual frameworks of teleconnections and telecoupling seek to explicitly link land changes in one place, or in a number of places, to dist...
