In 2015, the European Commission published a report on technology and measures for road user safety. This report provided initial feasibility, cost and benefit information for over 50 candidate safety measures that could be implemented as part of the amendment to the General Safety Regulation and the Pedestrian Safety Regulation.

The 2017 study reviews in more detail the 24 candidate measures selected by the Commission for potential inclusion in the regulations, and updates the information presented in the 2015 study with recent data. It also examines in greater detail the robustness of the available evidence for inclusion as input in further impact assessments or cost-benefit studies.
