An integrated urban systems model with GIS
The ceaselessly increasing number of trips on urban highways and major arterial roads have caused serious congestion and air pollution problems. Thus many transportation agencies have persevered in their efforts not only to alleviate such problems, but also to minimize social costs. However, the complex nature of such problems has strongly hindered transportation agencies’ ability to consider a...
متن کاملAn Integrated System for Urban Model Generation
Many tasks in the context of urban planning presume 3D city models, where buildings are represented separately from the terrain surface e.g. by 3D boundary representations. One of the most promising approaches to solve the challenging task of automatic 3D city model acquisition is the integration of multiple data sources to benefit from the complementary types of information. In our approach he...

متن کاملMAGUS: modelling access with GIS in urban systems
The project aims to develop, test and apply a Geographical Information System (GIS) for modelling access for wheelchair users in urban areas. The principal focus is to provide a GIS system that will work as a decision support and mapping tool for urban planners. In addition, the system has been designed to encompass future developments, including use as a guidance device to help wheelchair user...
متن کاملModel connectors for integrated simulations of urban wastewater systems
In order to perform simulations of the integrated wastewater system, state variables of sub-system models (sewer, activated sludge, river) must be translated from one model to the other. A connector between ASM1 (Henze et al. 2000) and RWQM1 (Shanahan et al. 2001) is described in this paper to introduce the general approach developed to overcome this necessity. Inherent features of this connect...
