Measurement of emission in real traffic

Measurement of emission in real traffic

Měření emisí v reálném provozu

Air pollution is caused by a number of sources, including road transport. In order to determine the contribution of transport to production of pollutants, the real driving emission measurements are the most suitable. In contrast to homologation measurements, which determine emission factors of new vehicles, for the knowledge of the real impact on the environment it is necessary to monitor production of pollutants by vehicles operated short-term to long-term, when gradual deterioration, related to the period and way of use, is reflected in the emission production.

The department activities focus on measuring limited and non-limited pollutant real driving emissions. Measurements in real conditions are also preferred by EU bodies, which call to research institutions with a requirement to intensive data collection. Particularly in case of non-limited pollutants, it is still little explored issue encountering insufficient data and knowledge base. In the field of the method determination of emission factors of these substances with the use of data from real driving emission measurements, it allows their classification into different types of traffic (e.g. urban, rural, motorway). For this reason, a unique mobile device is used, developed in cooperation with Transport Research Centre and company SEKO Brno, s.r.o.

The measurement results can be used for production of conception materials in the field of clean mobility and sustainable transport, designs, setting and evaluation of economic and fiscal tools in road transport. The use of measured data helps to complement activity data served to processing emission inventory in the Czech Republic, which are reported at the international level. The measurement device offers a wide range of uses for research and development activities; see mobile laboratory offer.
