In 2008, the Danish Technological Institute was given accreditation to perform emission measurements on busses in city areas – this reduces air pollution in the cities.
Measurements are made of the small ’cloud’ emitted by the busses when the driver steps on the gas and moves away from the bus stop.
The Danish Technological Institute has formulated the environmental requirements for the measurements together with Trafikselskabet Movia. The traffic companies in Odense, Aalborg and Aarhus have implemented the environmental requirements from Trafikselskabet Movia.
The emission measurements show a need to improve the maintenance of particle filters. The Danish Technological Institute is therefore focusing on making the bus garages involved observe the suppliers’ maintenance instructions for the particle filters.
