Vehicle-Based Road Dust Emissions Measurements

TRAKER is a vehicle-based method for measuring road dust emissions. Particulate matter is sampled in front and behind a vehicle’s tire and the difference in PM concentration (TRAKER signal) is used to infer the airborne flux of particles from the roadway. Two independent tests indicated that the TRAKER signal increases as the cube of the speed for a given road dust loading. Simultaneous measure...

A new approach to model tyre/road contact

In the Structural Dynamics and Acoustics group at the University of Twente, we aim to develop a quantitative tyre/road noise model. An essential part of this model is an accurate contact algorithm which is fast enough to simulate tyre vibrations up to the acoustic frequencies. In this paper we present a contact algorithm, describing the contact between a tyre and a road surface, which has the p...
