Methodology

All of the research summaries presented on the Road Safety Observatory has been produced following the same general methodology, although individual papers may have used additional approaches, in which case this is described in the individual research review.

The research reviews were limited to:

  • Evidence published by the Department for Transport and its contractors
  • Evidence identified from an internet search using search terms relevant to the particular topic
  • Evidence identified from the websites and research databases listed below.
  • Research published within the last 15 years, except where seminal pieces of work were conducted previous to this.

Important Notes

The reviews of evidence on this site have been commissioned by the Road Safety Observatory Programme Board and reviewed by an independent Evidence Review Panel before publication. The reviews are neither systematic nor fully comprehensive. They represent a summary of the best evidence readily available to the research community, and will be kept under review and amended as required, for example, as new evidence emerges.

The Programme Board is not liable for the content of the reviews. The reviews are intended to be free from bias and independent of Government policies and the policies of the individual organisations on the Programme Board. Therefore, they may not always represent the views of all the individual organisations that comprise the Programme Board.
