The report consists of four parts. Part 1 estimates effects of campaigns on road accidents, fatal accidents and serious injury accidents by means of meta-analysis. Effect of campaigns in the campaign period is ca 9% reduction in the number of accidents (p<0.05). Effect of campaigns in the after-period is a reduction of ca 15% (p<0.05). Mass-media campaigns (TV, radio and newspapers only) have no effect on the number of accidents. Police enforcement, length < 200 days and personal influence contribute significantly in explaining the effects on accidents. Part 2 uses meta-analysis in estimating effects of campaigns on other behavioural areas than road traffic, for example sex behaviour/HIV-protection, diet and physical activity, at home- and leisure-time accidents etc. Part 3 addresses six Swedish campaigns and discusses evaluation requirements, the objectives of the information activity as part of the concerns of the Swedish Road Administration, and as an element in larger measure packages, and part 3 also suggests proposals for improvement. Part 4 appraises and estimates cost-effectiveness and benefit-cost aspects regarding six of the Swedish Road Administration’s campaigns.
