- KonferenzbeitragFloating Car Data as Data Source for Modelling of Air and Noise Pollution in Regions with High Traffic Density(Environmental Communication in the Information Society - Proceedings of the 16th Conference, 2002) Nowotny, Bernhard; Maurer, Peter; Schechtner, Katja; Winiwarter, Wilfried; Zajicek, JürgenAs air and noise pollution models depend on real-time traffic data, the integration of traffic information (air and noise emissions) has been recognised as an important step in urban areas. As the equipment of fixed measurement stations for traffic, air pollution and noise detection is limited by financial constraints information from cars equipped with sensors (Floating Cars) supplements information from these sources. The position and the speed of cars are acquired by satellite navigation in combination with mobile communication, cellular phone tracking systems and long wave positioning. Further knowledge of the relation among traffic-related parameters is used to estimate traffic flow in the road network. Based on the estimations available models for traffic-related air and noise emissions can be applied to calculate emission inventories with an improved spatial and temporal resolution. So the development of methods for the detection, storage and interpretation of Floating Car data has the potential of improving the information basis for modelling of the traffic situation, air and noise pollution in regions with high traffic density.
- KonferenzbeitragMultiple Dependencies and Scenario Management in Emission Inventories(The Information Society and Enlargement of the European Union, 2003) Humer, Heinrich; Winiwarter, Wilfried; Schimak, GeraldAssessment of emissions of air pollutants consists of very simple calculations. However, difficulties arise by combining very different sources of input data in a sophisticated structure and to keep these data well organized. We show in this paper an approach to support air quality experts in preparing these input data, to evaluate combinations of abatement options by managing data groups and scenarios, and to provide a quality maintenance tool to the expert group which allows to evaluate and to document all data and algorithms also for a long term observation. The framework of this development was an application service providing (ASP) concept, as several users (e.g., from different Austrian provinces) should be able to share calculation algorithms as well as maintenance of server and database platform.
