Sharing Road Safety: Developing an International Framework for Crash Modification Functions

This is a summary of the Sharing Road Safety report developed by a group of international experts representing 18 countries, under the aegis of the Research Centre of the International Transport Forum at the Organisation for Economic Co-operation and Development (OECD). Road safety policy is increasingly dependent on sound indicators of the effectiveness of interventions. Crash modification factors and crash modification functions (CMFs) are indicators that quantify the crash reductions that result from interventions. The purpose of this report is to emphasize the importance of sharing knowledge on the effectiveness of interventions and disseminating the results internationally. This summary document comprises the key messages and recommendations, as well as the table of contents of the full report, together with details of the experts who contributed to the work.
