AboutÂ
More than two weeks have passed since my last post. The reason for not publishing something new was a conference, in which I had to participate and present a part of my research work. The conference was TRA 2014 and took place in Paris. I spent almost the entire previous week there. In the paragraphs below, you will find a text version of one of the papers that I presented there. If you like, you can download the original poster version in PDF format. I hope that you will find it interesting. Maybe within the week, I will publish another poster from the TRA conference.
Â
Introduction
- Improvement, determination, and harmonization of road transport exhaust PM emission factors (EF). Several other compounds are included (34 compounds in total).
- Vehicles/Technologies: all vehicles / all technologies (pro-Euro – Euro 7).
Â
Method
- COPERT 4 and a combined methodology (literature review plus COPERT 4).
- EFs correspond to urban, rural and highway conditions. For pre-Euro – Euro 5 technologies two different urban conditions (peak and off-peak).
- For technologies, pre-Euro and Euro1 – Euro 4 (PCs and LDVs), Euro I – Euro IV (HDVs, Buses, and Coaches) and Euro 1 – Euro 2 (Mopeds and Motorcycles), the database includes EFs for the EU-27 and each country member separately.
- For the newest technologies, only one EF for each pollutant for all EU-27 countries (it does not take into account the share of vehicles cars in different countries, the driving conditions or climatic conditions).

Road transport PM results
Passenger Cars and Light-Duty Vehicles



Heavy-Duty Vehicles, Buses, and Coaches


Â
Conclusions
- A database of road transport EFs was developed based on COPERT 4 and a detailed survey of the available literature.
- Although increased accuracy may be achieved by a more detailed procedure with COPERT (when the appropriate information and data be available), significant differences are not expected given the evolution of vehicle, fuel, aftertreatment, etc, technology.
