Analysis of TRWP Particle Distribution in Urban and Suburban Landscapes, Connecting Real Road Measurements with Particle Distribution Simulation

This article deals with methods and measurements related to environmental pollution analysis of particle distribution in urban suburban landscapes. Therefore, an already-invented sampling method for tyre road wear particles (TRWP) was used capture online emission factors from the road. The collected were analysed according their size distribution, use as input simulations. simulation model a main traffic intersection, because high vehicle dynamic density start–stop manoeuvres. To compare results (particle mass (PM) number (PN)) real-world emissions, measuring points defined over time 8 h during day. Afterwards, terms shape, appearance chemical composition, identify place origin. As result investigation, showed good correlation dynamics, even though there lot background influences, e.g., resuspension dust. Air humidity also great influence on recorded measurements. In areas such heavy braking or accelerating, more brake could be found.
