Simulation of a collision between a vehicle and a bicycle

The ever-growing demand for transport and the need to transport both people and goods have led to an increase in the congestion of road transport networks. Subsequently, the main negative effect is an increase in the number of serious road accidents. Of the total number of serious road accidents, a significant increase was registered among cyclists: in 2022, 13.9 % of the total number of vehicles involved in road accidents, compared with 6.6 % in 2010. This article is based on a thorough analysis of kinematic and dynamic parameters in the event of a collision of a vehicle, a bicycle and a cyclist assembled. To study the type of collision between a vehicle and a bicycle, we conducted a comparative analysis with respect to the distance by which the cyclist is thrown after the collision, changes in the speed of the vehicle and bicycle, changes in speed in the area of the cyclist’s head, as well as changes in acceleration recorded on the vehicle, bicycle and in the area of the cyclist’s head. Therefore, we have modeled a collision of a vehicle with a bicycle for two different cases, i.e. a head-on collision of a vehicle with a bicycle from behind and a head-on collision of a vehicle with a bicycle from the front.
