Post-implementation study of the Ekeberg tunnel. Sampling procedures, questionnaire, descriptive statistics and overall frequencies

In November 1996 1097 persons from 14 subareas in the town areas of Ekeberg and Old Oslo were asked about their opinion on neighbourhood quality and road traffic. Objective measures of road traffic, noise and pollution at the respondent’s home address have also been established. The study looks into the effects of major road projects in eastern Oslo. In this primary report we describe the sampling procedures and non-response, the questionnaire and simple descriptive statistics and frequencies.
