In this paper we analyse the profile of land use and population density with respect to the distance to the city centre for the European city. In addition to providing the radial population density and soil-sealing profiles for a large set of cities, we demonstrate a remarkable constancy of the profiles across city size. Our analysis combines the GMES/Copernicus Urban Atlas 2006 land use databa...

habitat associations of wild sheep, alborz red sheep (ovis orientalis gemelini x ovis orientalis arkali ), in khojir and sorkheh hesar national parks were studied over three seasons (spring, autumn and winter) in 2000. the position of observed maternal groups (including ewe with lamb) and male groups (including rams, barren ewes and juveniles) were determined on topographical maps during the fi...

Road traffic injuries and fatalities are increasing in Ghana. Police-collected crash and injury data for the period 1994-1998 were aggregated and analyzed using the MAAP5 accident analysis package developed by the Transport Research Laboratory, U.K. Published results of recent transport-related epidemiological and other surveys provided an additional data source. According to the 1994-1998 poli...

an urban map, the procedure composes the road-network by searching the roads from each intersection. Next, it In this paper, we propose an experimental method to modifies the road-network by interpreting the original urrecognize roads from an urban map on the basis of the ban map and the network simultaneously with heuristic road-network. The road-network is a conceptual graph knowledges about ...

Along with urbanization and decentralization, the sustainability of metropolitan areas is considered one of the most significant challenges worldwide. Transportation-related problems, such as congestion, GHG emissions, and excessive energy consumption, have been imposing tremendous pressure on the sustainability of metropolitan areas. As a noticeable component of urban form, local residential d...

in order to decrease the burden of cardiovascular disease (cvd), social determinants for cvd risk factors have been extensively studied in developed countries. however, few studies about them have been performed in low-middle-income countries. this study describes factors related to cvd risk factors in low-middle-income countries at a national level.data were assembled from international databa...

Designing and optimizing traffic behavior and animation is a challenging problem of interest to virtual environment content generation and to urban planning and design. While some traffic simulation methods have appeared in computer graphics, most related systems focus on the design of buildings, roads, or cities but without explicitly considering urban traffic. To our knowledge, our work provi...

Automatic road network extraction based on high resolution satellite image for urban planning holds great potential for significant reduction of database development/updating cost and turnaround time. Satellite remote sensing has been recognized worldwide as an effective technology for the monitoring and mapping the urban development. Two approaches for road network extraction for an urban regi...

Original scientific paper Planning of road transport infrastructure is a complex process. One of the major issues is determining the design elements of road infrastructure (road type and number of traffic lanes, cross-sectional profile, etc.). When designing roads, parameters from the international literature are used, containing values derived empirically from local data on traffic flow (mostl...
