Transcript

1. Modelling Noise in 3D: eNoiseADE 3D4EM Meeting June 21, 2017 Kavisha TU Delft 1
2. 2 3dgeoinfo 2017
3. Key points 3 1. Automate the process of data creation for noise simulation 2. Storage and representation of the results of noise simulation (CityGML) Standardize the 3D input and output data for noise simulation
4. Noise standards in NL 4 1. Industrielawaai IL (Industrial Noise) 2. Wegverkeerslawaai RMW 2012 (Road Traffic Noise) 3. Railverkeerslawaai RMR 2012 (Rail Traffic Noise)
5. Inputs for IL & RMW-2012 5
6. Noise data modelling 6 Software: Geomilieu Input data: BGT & AHN3 (NWB??) Output: CityGML eNoise ADE (Industrial and road noise)
7. 7 IL
8. 8 RMW-2012
9. 9 = receiver points along the building facade ⇠ 3m ⇠ 6m ⇠ 9m ⇠ 12m Ground level = points in a 10mX10m grid at 4m height (prescribed by END) Automatic generation of Receiver points
10. CityGML Noise ADE 10 1. Road traffic and railways noise 2. No support for industrial noise 3. No info about noise barriers 4. No distinction in the speeds of vehicles 5. No noise data for wide frequency range.
11. CityGML Noise ADE 11
12. eNoise ADE 12
13. eNoise ADE 13 For buildings • reflection values (octave band) • receiver height (1..6) • receiving facade • noise levels (D/E/N)(octave band)
14. 14 CityGML Noise ADE
15. eNoise ADE 15
16. eNoise ADE 16 For light & heavy vehicles • speed (D/E/N) • traffic flow (D/E/N) • intensity (D/E/N)
17. eNoise ADE 17 For noise barriers • name, id ,desc. (GML) • reflectance values (octave bands)
18. eNoise ADE 18 For industrial sources • operating hours (D/E/N) • emission values (octave band)
19. eNoise ADE 19
20. Now? 20 1. Paper on terrain ADE (ongoing) 2. Implementing the rest of the noise model (ongoing) 3. Terrain LODs (just started) 4. Flood modeling (?? need to talk about it!)
