In this paper we focus on a visualization tool for car crash simulations. By means of some examples we show how various data pre-processing features can facilitate the engineer’s work. For example, parts can be assembled, replaced, welded, bonded, or deformed. Data pre-processing within the visualization tool means that some modifications can be done directly on the finite element mesh which is...

Rollover is not the most common type of accident, but the consequences may be serious. Understanding of the injury mechanisms during the complex rollover movement is limited and requires further investigation. ln-depth investigations of 21 Volvo cars involved in rollover crashes were analysed with regards to cause and outcome. Detailed information was examined about the crash scenario, the road...

ABSTRACT This study aimed to use a simulated vehicle asses quantitatively the head and neck injuries of occupants, in frontal car crash, when driver has only one hand on steering wheel, such as while using cell phone driving. First, we conducted survey NHTSA reports real laboratory tests collisions involving sedans. The effects these Hybrid III 50th percentile male crash test dummy were measure...

Research was undertaken to determine vehicle size parameters influencing driver fatality odds, independent of mass, in two-vehicle collisions. Forty vehicle parameters were evaluated for 1,500 vehicle groupings. Logistic regression analyses show driver factors (belt use, age, drinking) collectively contribute more to fatality odds than vehicle factors, and that mass is the most important vehicu...

The focus of this paper is on a large-scale reliability based design optimization of a car body structure for crash safety. The application of multidisciplinary design optimization (MDO) to automotive vehicle structure design has been an interest topic over the past several years (Yang et al. 1994, Schramm et al. 1999). Sobieski et al. (2000) and Kodiyalam et al. (2001) reported a method with v...

This paper presents the first experiment managed as part of the Sciences and Technologies for Safety in Transport (ST2) program, a French national research project. In this program, human physical reactions are studied in order to adapt primary and secondary safety systems to driver behavior. The objective of the present study was to examine how car drivers modify their posture just prior to a ...

BACKGROUND One of the major causes of death among children younger than 15 years is vehicular injury. Car safety seats protect children in a crash if they are used correctly. The objective of this study was to assess the level of parental knowledge and their attitudes regarding car safety seats. METHODS The survey was conducted in May and June 2007 at Bakirkoy Dr. Sadi Konuk Research-Training...

Carshare systems are considered a promising solution for sustainable development of cities. To promote carsharing it is imperative to make them cost effective, which includes reduction in costs associated to crashes and insurance. To achieve this goal, it is important to characterize carshare users involved in crashes and understand factors that can explain at-fault and not-at fault drivers. Th...

Every year nearly 1.5 million people are dying in traffic collisions around the world, due to unexpected behavior of pedestrians while crossing road. To address this problem an augmentation function for predicting crash risk active pedestrian is proposed. The has several functions like pre-crash scenario, vehicle trajectory, and trajectory. In a Pre-Crash movement such as entering road boundary...

reviews in many countries indicate that drivers often talk on mobile (cell) phones. studies have been done on possible effects of concurrent mobile phone use on driving performance. previous studies have found that phone talking could impairs performance on simulated or instrumented driving tasks, using such measures as reaction time, following distance, and situational awareness. most of these...
