In this paper four pedestrian models will be presented: three 2-dimensional models with 2, 5 and 7-segments respectively and one 3-dimensional model with 15 segments. All these models were formulated with the general Crash Victim Simulation package MADYMO. Model results will be compared with the experimental results of a Part 572 dummy impacted lateral at two velocities (30 and 40 km/h). The reliability of the models with respect to their complexity will be discussed. Special attention will be given to the mathematical representation of the contact between the pedestrian and sharp vehicle edges and the visualization of the complex 3-dimensional pedestrian motions with a recently developed 3D-Graphics Package.read more

Pedestrian crash reconstruction using multi-body modeling with geometrically detailed, validated vehicle models and advanced pedestrian injury criteria
L Van Rooij,Kavi Bhalla,Mark Meissner,J. Ivarsson,Jeffrey Richard Crandall,Douglas Longhitano,Yukou Takahashi,Yasuhiro Dokko,Yuuji Kikuchi +8 more
TL;DR: In this article, the authors developed a method for studying pedestrian to car impacts through detailed multi-body modelling of various pedestrian anthropometries and vehicle types, which can distinguish the injury severity for various body parts at impact locations on the vehicle.

A Study of Influences of Vehicle Speed and Front Structure on Pedestrian Impact Responses Using Mathematical Models
TL;DR: In this article, a validated pedestrian multibody model was used to investigate the influences of impact speed and vehicle front structure on the pedestrian dynamic responses in vehicle collisions, and the possible benefits from speed control in urban area were assessed, and a feasible speed limit was proposed to reduce the risks of pedestrian injuries.

Vehicle-pedestrian collisions: Validated models for pedestrian impact and projection
TL;DR: In this paper, two models are presented for pedestrian forward and wrap projection impacts, which are predicated on separating the total projection distance into the individual projection distances occurring during three principal phases of the collision.

Computer Simulation of Impact Response of the Human Knee Joint in Car-Pedestrian Accidents
Jikuang Yang,Janusz Kajzer +1 more
TL;DR: Analysis of results from previous mathematical simulations of pedestrian impacts shows that a standard description of the pedestrian model used in the MADYMO is not comparable with simulations performed with biological materials, so a 3D pedestrian knee joint model was developed to achieve a better correlation with the results of previous cadaver experiments.
