International Co-operation on Theories and Concepts in Traffic safety (ICTCT) 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 does so by organizing 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.
Transport & Roads has played an important role in ICTCT since its very beginning in the late 1970s. Several ICTCT conferences has been hosted in Lund, while the department has been constantly represented in the Steering Committee of the association.
