The Handbook of Road Safety Measures summarizes results from empirical studies that have investigated safety effects of different types of road safety measures. As far as possible, results are summarized by meta-analysis. The present report contains the introductory part of the Handbook. A short version is published in the online version of the Handbook at tsh.toi.no. The report presents some background information, including a summary of vision zero, general information about crashes and crash risk in Norway and internationally and an overview of crash costs and cost-benefit analysis. It also contains an introduction to meta-analysis, including guidelines for systematic reviews and the basics of the most important statistical methods in log odds meta-analysis and analysis of potential biases.
