“…Furthermore, this work reports data corroborated with experimental tests with dummies (adult size) and bodies. The second set of empirical data reported on [31,32,33,34] are related to a vehicle's experimental tests (high geometry)pedestrian frontal collisions. It was performed with child-sized dummies.…”

A Free access tool based on a pedestrian-vehicle collision model is presented. The model permitted the qualitative and quantitative description of the event's whole dynamic by segments called pre-collision, collision, and postcollision. Furthermore, it enabled the determination of the magnitude of the vehicle's initial speed before the collision with a pedestrian and the location of the point position of impact on the road where the accident occurred. The model's inputs are related to the evidence collected at the scene, which provides a checklist platform for supporting investigators' fieldwork. Additionally, the pre-collision segment permitted the investigators to develop an avoidability study that may contribute to road safety evaluation. The model was validated, comparing the results statistically with experimental cases developed with dummies, bodies, and reconstructed cases. It is shown that there is no significant difference, thus verifying its functionality. The tool is available as a mobile app in Spanish and English, allowing significant affordability to investigators from some low and middle-income countries.

“…• projectile models, where a pedestrian is assumed to be a point mass [146]; • empirical models, described by single-argument regression equations, which are based on statistical approximation of results of dummy experiments or real accident analyses [42,132,160]; • two-and three-segment 2D analytical models, which assume the pedestrian body to be made of stiff segments connected with a hinge joint [156,197]; • numerical models of an entire human body.…”

The review paper discusses numerical human body models of pedestrians. The background of current trends in physical and mathematical pedestrian research is presented. Development, validation and areas of application of pedestrian body models are described. The differences between multibody models and finite element models are presented. Accident-based and experimental approaches to validation of the models are discussed. As a novelty, this paper presents an overview of multibody models used in forensic investigations, discusses their usefulness, and differences between their design and the design of more advanced multibody and finite element models. Finally, the most recent trends in human body modelling are discussed, including open-source approaches to model distribution and replacement of physical tests by digital simulations.
