Traffic emissions using IMMISem IMMISem.flyer.1s.en.doc/23.04.12 Dynamic emission inventories The creation and regular updating of emission inventories is a standard task in maintaining air quality. For that purpose IVU Umwelt developed a program system for dynamic emission inventories (EKatDyn) supporting the completion of this task in a user-oriented and effcient manner. The makes use of the GIS integrated model IMMISem to calculate emissions. Basic data to calculate emissions • emission factors for a selection of relevant road types or traffic conditions in the city (HBEFA) • motor vehicle fleets (HBEFA up to the prognosis year 2030) • a cold start model for different road properties or road functions, that can be used in any combination with traffic conditions • a model for the dynamic consideration of Stop&Go traffic Consideration of different effects • consideration of tire wear for soot emissions • consideration of resuspended dust, tire and break wear for emissions of PM10 and PM2.5 • effect of particle filter • driving bans for different types of vehicles and concepts (Environmental/Low emission zone) • effect of air conditioning in cars • individual emission factors • calculation of BaP / PAK emissions Street parameters • traffic condition and road function • Stop&Go fraction or of capacity or number of lanes of the road • road gradient • average daily traffic (MDT) • MDT fractions of motorcycles, heavy and light commercial motor vehicles as well as buses Input dialog of street relevant parameters Emission time series The hourly-emission-model IMMISem,h can be used to establish time series of traffic induced emissions based on detailed traffic data or time series. Detailed information to IMMISem are available at http://www.immis.de/. The software IMMISem 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.
