The possibilities of using an outline crash sketch in modelling and simulation of accidents

The paper underpins the reconstruction and analysis of a vehicle - motorcycle-biker-assembly collision type by means of a graphical method. The virtual modeling of the traffic accident reconstruction was achieved by complying the traces and the distances identified; hence it was imported and developed the accident scene sketch. Following the numerical processing of the simulation, the vehicles speed during the pre-collision, collision and post-collision phases was determined in graphical form, generating speed and space variation diagrams.This work is published under NOCC (the "Licence").

MODELING AND ANALYSIS OF KNEE - DASHBOARD IMPACT IN FRONTAL COLLISION

During the frontal collision of a vehicle, be it with another vehicle or with a fixed or mobile obstacle, one of the most frequent injuries suffered by the driver of the vehicle occurs in the knee joint. Thus, the present paper aims at investigating the knee to dashboard contact during a frontal collision. Admittedly, the first stage of our investigation underpinned the design of a model to encompass the dummy and the main interior elements of the vehicle. Subsequently, the main types of contacts provided by the LS-DYNA software have been analysed. In order to establish the optimal modelling variant of the impact between the knee and the dashboard various simulations have been carried out while applying different methods to define the contact. The results obtained following the simulations have been then compared to the results provided by the specialized literature

Perception of 3D Virtual Road Markings - Based on Estimation of Vehicle Speed

Excessive speed and poor drivers' perception are the causes of a large number of traffic accidents. Analysis of the influence of geometry in drivers' behavior has been widely performed by different researchers. One way to improve road safety is to provide adequate visibility in order to help drivers adopt adequate behaviors. When the budget is not sufficient for expensive traffic solutions, innovative but simple solutions can be implemented. In this study, the experiment was performed to explore how drivers' perception and behavior are influenced by two virtual 3D shapes' projections - a 3D alternative crosswalk pattern and speed bumps consisted of triangular prisms. The results show statistically significant differences between drivers' willingness to reduce vehicle speed as a response to the two types of road markings: the first one with the square shape base (rectangular prism) and the second one with triangular shape base (triangular prism)
