This paper describes the VEDYAC (VEhicle DYnamics And Crash) computer program for simulating collisions between cars and cyclists. In doing so, this model is divided into the following submodels: (1) the VEDYAC dummy model; (2) the VEDYAC bicycle model; (3) the VEDYAC vehicle front model; and (4) the VEDYAC road model. The paper also describes the interactions between these submodels. Finally, the paper presents the VEDYAC2 model which is a new version of VEDYAC. VEDYAC2 was developed for simulating side collisions of cars against cyclists. This program was verified using the results of a number of TNO Road Vehicles Research Institute's experimental simulations.
