ICSC 2023 11th International Cycling Safety Conference, The Hague, the Netherlands

The International Cycling Safety Conference, hosted by SWOV on November 15 to 17, brought together almost 200 delegates from over 25 countries to bike through the Hague, experience workshops on bicycle streets and bicycle simulators, meet other people professionally interested in cycling safety, learn from each other and share knowledge. The extended abstracts for all presenters can be found in the Book of Abstracts. In addition, a special issue of Traffic Safety Research for ICSC 2023 is open to submission of full papers of all accepted abstracts until January 31.
