Abstract
Urban development and densification cause noise problems that can have a negative impact on human health. In 2002, the European Union (EU) stated the European Noise Directive (END) with the purpose to evaluate environmental noise levels (including the sources road, railway, and air traffic) in the member states every 5 years. To make the result of the evaluations comparable between countries, the CNOSSOS-EU model has been provided as a noise simulation standard.
Noise simulations require information about noise sources and propagation conditions. For this geographic information is required such as 3D city models and road databases. In Sweden there is an ongoing work to standardize 3D city models denoted as the 3CIM model. This thesis... (More)

In Sweden there is an ongoing work to standardize 3D city models denoted as the 3CIM model. This thesis aims to evaluate the capability of 3CIM to be used as input data in road traffic noise simulations in accordance to the END-directive. To make the original data readable in the SoundPLAN noise simulation software, the 3CIM and road datasets, together with a height model (DEM) was tailored in FME to generate the input data. By mapping attributes, the input data was imported to SoundPLAN. The noise simulation output consisted of a map presenting noise levels on the façade were as well as noise level tables for noise sources and receivers.
The thesis discusses the limitation of the current 3CIM and road datasets as input data for noise simulations as well as the problems that may occur when performing noise simulations in SoundPLAN. Finally, it provides possible solutions to improve the input data, and solve the programming running problems. (Less)
Popular Abstract
With the ongoing urbanization in recent years, more traffic noise affects human health, especially in urban areas. The noise causes a series of health problems such as sleep disturbance, distraction, and depression. It is necessary to get knowledge about urban noise to avoid its negative effects. Due to that measuring noise levels is resource-demanding and time-consuming, the governments in many countries (e.g. German, Netherlands) decided to use noise simulation models to evaluate urban noise levels. To make the simulation results from different countries harmonized and comparable, European Noise Directive (END) developed the CNOSSOS-EU model. All European Union (EU) member states are supposed to use the CNOSSOS-EU model and submit the... (More)
With the ongoing urbanization in recent years, more traffic noise affects human health, especially in urban areas. The noise causes a series of health problems such as sleep disturbance, distraction, and depression. It is necessary to get knowledge about urban noise to avoid its negative effects. Due to that measuring noise levels is resource-demanding and time-consuming, the governments in many countries (e.g. German, Netherlands) decided to use noise simulation models to evaluate urban noise levels. To make the simulation results from different countries harmonized and comparable, European Noise Directive (END) developed the CNOSSOS-EU model. All European Union (EU) member states are supposed to use the CNOSSOS-EU model and submit the evaluation results in every 5 years. Since Sweden has been involving the END’s project, it needs to use the national 3D city model 3CIM as the input data and then perform the noise simulations based on the CNOSSOS-EU model. However, the 3CIM as a national specification may be unable to be imported to the noise simulation software that supports the CNOSSOS-EU model directly.
This thesis aims to evaluate the capability of 3CIM to be used as input data in road traffic noise simulations in accordance to the END-directive. To make the original data readable in the SoundPLAN noise simulation software, the 3CIM and road datasets, together with a digital elevation model (DEM) was tailored in the Feature Manipulation Engine (FME) to generate the input data. By mapping attributes, the input data was imported to SoundPLAN. The noise simulation results were output as a façade noise map and noise statistic tables.
The thesis discusses the limitation of the current 3CIM and road datasets as input data for noise simulations as well as the problems that may occur when performing noise simulations in SoundPLAN. Finally, it provides possible solutions to improve the input data and solve the programming running problems. (Less)
