background and aims: this study aimed to evaluate the effect of enforcement of new traffic laws on the fatal and non- fatal injury rates in iran. methods: in a longitudinal, interventional controlled trial study, all subjects with history of fatal and non-fatal injuries were studied. their injuries were caused by six risky violations (unauthorized speed, illegal overtaking, red traffic light cr...
This paper presents a true ortho-image generation scheme in urban areas for web GIS application such as urban management system. Proposed scheme includes the solution of conventional problems in normal ortho-image generation. Especially, our approach is focused on the automation and consistency of ortho-image in complex urban areas. For this purpose, we generated additionally plotted DSM (Digit...
nowadays,tourism industry considered as one of the main sources of income of a country.unfortunately and despite of owning plenty of cultural historical and natural attractions, iran has not reached to a proper position in this field. besides, the historical cities of a country are considered as the income resource and national wealth of it. qazvin with a rich cultural precedent, have suitable ...
An urban microeconomic model of households evolving in a 2D cellular automata allows to simulate the growth of a metropolitan area where land is devoted to housing, road network and agricultural/green areas. This system is self-organised: based on individualistic decisions of economic agents who compete on the land market, the model generates a metropolitan area with houses, roads, and agricult...

Worldwide, metropolises of today are often prone to damage from natural hazards by various reasons. One of the slope instabilities that causes financial and human losses annually on socio-economics and the environment are landslides. There are tens of landslides that occur in different parts of the country each year, which threaten more residential areas, roads and facilities. In this study we ...
while risk reduction has been mainly addressed by seismologists and engineers by now, the total impact of earthquake greatly depends on urban planning factors. the effects of planning can be considered in the socio economic and physical aspects. urban planning may have a dominant role in various earthquake phases: at the time of earthquake; rescue, and emergency, as well as temporary and perman...
Understanding urban growth spatiotemporally is important for landscape and urban development planning. In this study, we examined the spatiotemporal pattern of urban growth of the Colombo Metropolitan Area (CMA)—Sri Lanka’s only metropolitan area—from 1992 to 2014 using remote sensing data and GIS techniques. First, we classified three land-use/cover maps of the CMA (i.e., for 1992, 2001, and 2...
today the image of a permanent skeletal space of cities affected by some forces or mechanisms is put in time with social-economic development and while imposes a new face and perspective to physical anatomy of cities, and prepares field to changes in content and social- economic structures of cities too. simultaneously with quitting villages in order to settle in cities by villagers, the phen...
Urban heat island (UHI) effects can strengthen heat waves and air pollution episodes. In this study, the dampening impact of urban trees on the UHI during an extreme heat wave in the Washington, D.C., and Baltimore, Maryland, metropolitan area is examined by incorporating trees, soil, and grass into the coupled Weather Research and Forecasting model and an urban canopy model (WRF-UCM). By param...
