The Forum of European Road Safety Research Organisations (FERSI) is organising the FERSI conference 2021 which will take place on 28-29 October 2021 in Hague, Netherlands. The conference focuses on the exchange of national and regional experiences with implementing evidence-based road safety measures, both positive and negative ones. There will be a specific focus on the road to successful implementation, including overcoming the barriers encountered along the way. The conference will allow for discussion of promising ways to facilitate the decision making and implementation process of proven (cost-)effective but politically sensitive road safety measures.
