EU Noise mapping experiences and action planning for the Grand-Duchy of Luxembourg

摘要

For the Grand-Duchy of Luxembourg, EU-conformant noise mapping and noise exposure assessment has been performed for road, rail and aircraft noise. Initial GIS data required extensive refinement and merger with road traffic simulation data as well as rail traffic data provided by the rail authorities based on various sources of less common data formats. The data integration process, which resulted in a comprehensive state-wide model, utilized LimA macro technology. The major reasons and issues for refinement and the chosen solution will be presented. In support of action planning an automatized strategy for local mitigation schemes will be suggested. For the railway noise propagation a "word by word" interpretation of the standard was applied, which implied a mixed 2D/3D geometry interpretation. Results from this will be compared to a consistent 3D interpretation. For aircraft noise calculation ECAC Doc 29 was applied and data assembling as well as final results will be presented.
