KoFeMo

Combined Investigation of Particulate Matter and Mobility

Sponsor: BMV – Federal Ministry of Transport

Contact person: Guido Lehne, Tianyu Xu, Dimitri Ivanov

Summary of the overall project:

The research project ‘KoFeMo – Combined Investigation of Particulate Matter and Mobility’ is investigating how particulate matter pollution in cities changes spatially and temporally in an exemplary urban district and how this is related to traffic, weather and transregional influences. The focus is on emissions from brake and tyre wear, which occur in particular at heavily polluted traffic junctions. A networked, mobile measuring system is used for this purpose, which records particulate matter data horizontally and vertically at high frequency and transfers it to a database in near real time. The measurements are supplemented by DSGVO-compliant traffic recording (vehicle classes, traffic flow) and meteorological data. Based on this data, KoFeMo is developing a multi-scale simulation and AI framework that models and predicts particulate matter dynamics in the neighbourhood. The aim is to derive effective measures, such as intelligent traffic flow control and lower-emission driving profiles, and to make the quality-assured measurement and simulation data publicly available.

Goals and tasks of iPAT

• Distributed stationary, horizontal measurement of particulate matter concentration at intersections
• Mobile measurements of particulate matter concentration on vehicles for source characterization
• Development and simulation of coupled CFD-DEM simulations on a vehicle wheel scale for quantifying the transport, agglomeration and deposition of brake/tyre particles under varying environmental and operating parameters
• Derivation and transfer of scale-reduced models for integration into overall vehicle modelling
