Abstract: Driving conditions have a large influence on particle generation from brake and tyre wear processes. Different driving conditions in experimental investigation of particle emissions from brake and tyre wear is one of the reasons why different - or even sometimes- contradictory conclusions are reported. In order to harmonize future studies on particles from brake and tyre wear and improve the comparability of the relative results, the definition of “normal” or “typical” driving patterns has been identified by PMP group as an important working item. The proposed approach is to use activity data collected in the framework of other projects in order to investigate typical acceleration / deceleration frequency distributions. The main objectives of this activity are to compare “typical/normal driving conditions” derived by existing datasets like the WLTP vehicle activity database with the industry standards, as well as to reach, if possible, a shared definition of normal, severe, extreme or infrequent conditions. This will narrow down the range of driving conditions to be taken into consideration as far as non-exhaust particle emissions are concerned and will improve the comparability of future studies. This report describes the results of a detailed analysis of the WLTP in-use database. The results are provided in this report and in dedicated ACCESS databases.
