The issue of noise emissions and immissions plays an important role in urban planning processes. You can use IMMI's full range of features for corresponding investigations: the import of GIS data sets, segmented calculation in the network, the creation of calculation lists for comparison of different variants or exposure analyses.
Probably the most challenging task is noise mapping according to the EU directive. IMMI has been and still is used successfully in numerous projects: whether for a city like Berlin, federal states like Bavaria or Baden-Württemberg, or for counties in the UK.
- In Germany, in accordance with the requirements of the noise mapping regulation (34. BImSchV) combined with §§ 47 a-f BImSchG and the calculation regulations VBUS, VBUSch, VBUI, VBUF and VBEB
- Throughout the EU according to national regulations
- As of 2019, according to CNOSSOS-EU with national implementation
The calculation of strategic noise maps for the noise indicators LDEN and LNight is carried out in 10 m increments and at a height of 4 m, separately for each type of noise. The exposure analysis for evaluation of the affected persons according to 34th BImSchV is realized by calculating facade levels. The performance features multicore, segmented calculation, and ACC – distributing the calculation in the network – are for the calculation of noise maps and facade levels on any number of computers ensuring short computing times.
- Data import etc. via: ArcGIS, QSI, DXF, ASCII
- Unlimited number of obstacles (buildings, walls)
- Support of large-size terrain models and simplifying functions
- Input of the building use (e.g. residential building, school, kindergarten, hospital, uninhabited), number of storeys, dwellings, inhabitants
- Automatic calculation in the network
- Numerous control functions for quality assurance
- Data export
- Evaluation functions: Create conflict maps, hotspot analysis, differential grids.
With noise action plans according to EU Environmental Noise Directive 2002/49/EC, cities and municipalities have a considerable influence on the reduction of road traffic noise. For noise action plans, we determine hot spots, develop reduction concepts in close collaboration with the planning committees, demonstrate the effectiveness of measures, plan quiet areas and provide support in reporting to the EU.
