The report describes results from a five year research program on road traffic and environmental annoyances. The analyses utilize a data base comprising 17 community surveys and 19000 respondents. The program has contributed to the establishment of national exposure-effect curves for road traffic noise, exhaust/-smell, dust/dirt and vibrations in dwellings. It also contributed to three standards NS 8176, NT ACOU 106 and ISO TS 1666:2003 on vibrations, and the assessment of people's reactions to vibration and noise. A model for the combined effects of noise at the dwelling and in the neighborhood and local air pollution on environmental annoyances has been developed. Measures improving the situation at a dwelling, along a street or for a whole city area, affect different parts of the model. The efficacy of these different types of measures is therefore different from what one would expect from partial single exposure single reaction models. Improvement strategies in multi-exposed areas should differ from those applied to a single exposure area. |
