ICTCT (International Co-operation on Theories and Concepts in Traffic safety) is an international association aiming since 1988 at building up and sharing scientific knowledge on road safety, with a particular interest for methods that do not only rely on crash data but also on non-crash events. It organizes conferences, courses and opportunities for knowledge transfer, all directed to a worldwide professional audience. ICTCT approaches safety as an integral part of the wider road traffic system, envisaging all transport modes with a specific emphasis on vulnerable road users.
