IMMISluft models traffic induced emissions and concentrations in city street canyons (additional load). It is based on the CPB model for street canyons and a box model for open building structures IMMISluft.flyer.1s.en.doc/23.04.12 Traffic induced air pollution using IMMISluft Validation • Diegmann, V., Mahlau, A.

Pollutants IMMISluft calculates annual values and 98%-percentiles of CO, CO2, NOx, NO, NO2, SO2, particulate matter (PM10), soot, HC, benzene, toluol, xylol, CH4, NH3, N2O, Benzo(A)pyren, PAK. EU directives characteristics • statistical characteristics of NO2 derived from NOx • exceeding probability of hourly limit value of NO2 • number of days with a daily PM10 mean value above 35 µg/m³ • 90,4%-percentile of PM10 daily mean value • highest sliding 8-hours mean value of CO Basic data of air pollution modeling • traffic data • background concentration e. g. using IMMISnet • meteorological data • geometry data of street canyon • start and end coordinates of street segment Schematic 3D-Representation of street canyons Emission modelling • modeling kernel of IMMISem based on Handbook emission factors for road transport (HBEfa) and VDI 3782 Sheet 7 • import of emission data • several methods for calculating resuspended dust and wear emissions Features • scaling of wind speed • customized meteorologies • several methods for deriving NO2-characteristics Interfaces • input data and results are stored in a Standard Dbase file; easy editing in Microsoft EXCEL • shape file und MIF export • LimA, Soundplan (noise) • VISUM (traffic modelling) Detailed information to IMMISluft are available at http://www.immis.de/. The software IMMISluft is available for Windows and as an Extension for ArcGIS®. IVU Umwelt offers expertise, studies and con-sulting using IMMIS, including data acquisition and preparation, graphical and numerical data representation and documentation, and impact analysis of measures to be taken.
