To study the environmental effects of the different stages of the traffic en-routing in Oslo East, a series of environmental studies is carried through. Some 3,600 person are interviewed and traffic, noise and air pollution levels are calculated. The reports shows that: The noise annoyance is considerably reduced after the traffic changes; The number of persons annoyed at a given level of noise in 1996 is much lower than in 1987. This 'area effect' is due to the many different environmental measures carried out in the area; Noise at work or on the way to work influences people's reactions to noise at home; The probability to report health symptoms increases with increasing noise level. |
