Environmental consequences of traffic re-routing in Oslo East. Summary of studies 1987-1996

Authors: Marika Kolbenstvedt
Report nr: 405/1998
ISBN: 82-480-0064-8
Language: Norwegian

The report presents results form a series of environmental surveys of the traffic re-routing in Oslo East, especially the Vålereng- and Ekebergtunnels, opened in 1989 and 1995 respectively. Some 3.600 persons are interviewed and traffic, noise and pollution levels are calculated. People's reactions are analysed in relation to the level they were exposed to each year. The traffic environmental load, and accordingly, people's troubles from traffic is considerably redused from 1987 to 1996. Together with environmental measures in the existing streets, the new tunnels have resulted in improvements of the whole area. Some 3.000 fewer persons are troubled by traffic and the nuisance at a given level of traffic and noise is lower today than in 1987. The most manifest improvements were along those stretches where the E6 artery previously traversed the district. But at the same time some areas have experienced a worsening of the situation, especially areas close to the tunnel entrances. The future challenge is to utilise the potential which traffic changes give for supplementary envi-ronmental measures in the district.
