Conclusions
The paper demonstrates a dual approach for vulnerable road user safety enhancement.
The investigation into the role of virtual computer simulations and the computer-
detection technology regarding pedestrians and cyclist safety was presented. The
advanced devices were presented and their advantages as well limitations in terms of
VRU safety were weighed. Further, the Autonomous Emergency Braking System was
characterised and its Human-Machine Interface was depicted.
However, when the collision is unavoidable the passive safety systems embedded
in vehicles are to react. The passive safety technologies have enabled great progresses
in death and injury mitigation. Consequently, in order to study the kinematics
involved in cyclist accident the virtual simulation using mathematical dynamic model
(MADYMO) was commenced. It needs to be noted, that several previous studies
involved the reconstruction of pedestrian real-world accidents using multi-body
models. Conversely, cyclists have been the subject of less research attention.
The second type of the numerical analysis was not as computationally efficient as
the multibody test, yet in enabled the authors to have a better insight into vehicles
stiffness. The coupling method was a unique capability that allowed the MADYMO
dummy to be used in a co-simulation with an external, LS-DYNA solver. The virtual
machine-to-human simulation of multibody pedestrian dummy coupled with the FE
model of a vehicle front-end was showed in the study.
