“…PC Crash also allows to simulate movement dynamics and vehicle impacts. Work (Dima et al, 2014) shows reconstruction of a passenger car collision with a truck using this program and the consistence of results was satisfactory. In turn, work (Coufal et al, 2014) provides a comparison and simulation of accident circumstances with the results provided with the use of Virtual Crash for a small overlap.…”

Road accidents which cause personal and material losses are inseparably connected with development of motorization. Currently, experts who provide assessment of vehicle accidents use simulation programs. The results of the assessments have an impact on legal procedures in court cases. However, experts are often unaware of simplifications in modeling and the possibility of comparing simulation results with the use of different models. In this work, problems connected with generation of different results for the same event by a program are discussed. The results can be used by researchers, program designers and experts in practice.

“…The most commonly used are PC-Crash, Virtual Crash and V-SIM (http://www.dsd.at; http://www.vcrashusa.com; www.cyborgidea.com.pl). In the works (Dima et al, 2014;Semela et al, 2007) the accidents were analyzed with the aid of PC Crash and Virtual Crash. In these studies a good representation of the crash pattern was obtained.…”

In today's world, many road users are exposed to the risk of accident. The consequences of the potential crash depend not only on the collision speed, but also on the type of vehicle. The article shows the problems connected with choosing an appropriate collision detection model in the case of a collision of two incompatible vehicles. In addition, directions and values of acceleration of inertia during the crash have been determined and presented. The case study is a collision of a motor car with a combine-harvester in which the problem of incompatibility is particularly noticeable. Simulation calculations were performed using the V-SIM4 code. Experimental verification has demonstrated practical application of a collision detection volumetric model, which best represents the impact of such a vehicle. The article also includes information on how to use the collision detection model in the V-SIM4 code, which may be used by court judges, assessors and investigators, as verification of these collision computers codes for cars is unavailable in the literature. Therefore, the subject of the article is both cognitive and practical.

This study presents the results of both a computer simulation of a vehicle crash into a rigid barrier obtained with V-SIM4 software and an experimental crash test published by ADAC (Allgemeiner Deutscher Automobil-Club). The results were obtained using the same initial conditions, which provides an opportunity to compare results and evaluate the reliability of simulation results. Observed errors and adopted models are discussed. The sensitivity of the post-impact motion to the overlap and engaged gear was studied, which is a result of non-linear phenomena occurring during the crashes. Expert witnesses (accident reconstructionists) often face such problems. Consequently, the important factor of any accident reconstruction is the knowledge of the expert and the identification of pre-impact conditions, which are uncertain. This study also addresses practical issues related to traffic collision reconstruction, employment of CCTV (closed-circuit television) in crash reconstruction, and directions in which software should be improved. The following results are useful for collision experts.
