In order to identify vehicles and traffic situations that have a negative impact on the environment, it is important to be able to measure emissions from individual vehicles in traffic. In this study an attempt is made to measure gases, particles and noise emitted from single vehicles in normal traffic. An apparatus for Fuel Efficiency Automobile Test (FEAT), by which emissions of NO, CO, HC and CO2 are measured, was combined with particle instruments for both total and size-distribution measurements, as well as noise measurements. The sampling of particles was done utilising a tube system for sampling on the road together with a dilution system. The noise measurements were done with two microphones at different heights. The measurements show that it is feasible to study regulated emissions, particle emissions and noise emissions from individual vehicles in normal traffic. Noise data was collected from ca 200 individual vehicles during the measurement campaign and the emissions of some of the vehicles were evaluated. The measurements were manually supervised and the evaluations mainly made by hand.
