Accidents are one of the main reasons of death for people across the globe, among which automobile accidents are a major portion resulting in fatalities and various injuries. Crashworthiness is an engineering concept that is used to analyse the ability of vehicle structure to cover and protect passengers in the case of an accident or impact. Crashworthiness aims to affect the design of the structure of the vehicle so that it absorbs as much energy as it can which is sustained from an impact by plastically deforming in a controllable behaviour. The remaining amount of the impact energy can then be handled by the restraint system to protect the occupants from the consequences of the secondary impact in the vehicle. The current trend in automobile design and manufacturing is to increase the number of lightweight and recycled components that forms the vehicle. In this way, an effort towards sustainable manufacturing and reducing carbon footprint is made. However, using unconventional materials might affect the strength and energy absorption capabilities of the automobile chassis and body that may induce a change in the crashworthiness of the vehicle. This study aims to bring insight into the effects of lightweight and recycled bumper beam system in vehicle crashworthiness through computational modelling. In addition, investigations of crashworthiness of different modifications that are made on the system geometry are carried out. Various finite element models embodying lightweight and recycled bumper beam systems are generated and simulated to evaluate several design choices and modifications.

Examination of the Relationship between the Vehicle Segment Used and Human Factors in Driving.
Azık, Derya; Yüzer Günay, Emel; Yüce, Ayşe Nur; Öz, Bahar (2019-07-05)
Road traffic accidents are important health problems globally and each year approximately 1.3 million people lose their lives and 50 million people get severely injured on the world’s roads as a result of these accidents (WHO,2015). In order to control road traffic accidents, a growing body of the literature investigates risks factors that could be broadly categorized as human, vehicle and environmental related factors (Shinar, 2007). However, while there are many studies that separately investigate these b...
Examining the approaches of OHS professionals to the reasons for falls from height
Akarsu, Deniz; Özkan, Türker; Department of Occupational Health and Safety (2019)
Except motor vehicles accidents, the death rate on occupational accidents which occur falling from high places or into depths, is higher than any other accidents. According to the importance of the topic, in the study, examining the approaches of OHS professionals to the reasons and effects of occupational accidents which occur as falling from heights is aimed. For this, 100 accident inspection reports from Labor Inspection Board were surveyed. Accident reasons were derived from those reports. Those reasons...
An approach to investigate relationship between speed and safety on urban arterials
Ardiç Eminağa, Zerrin; Akyılmaz, M. Özdemir; Department of Civil Engineering (2008)
Traffic safety is an important problem in today’s world with increasing number of fatalities and injuries in traffic accidents. For the solution of this problem, determination of accident prone locations on a network and reasons behind is an essential step, which is studied to some extend via different traffic accident analyses in the literature. While major factors affecting accident risk, such as speed, congestion, infrastructural aspects are known, it is still very difficult to figure out the interaction...
On Vehicle Aggressive Driving Behavior Detection Using Visual Information
Kumtepe, Omurcan; Akar, Gözde; Yuncu, Enes (2015-05-19)
Most of the traffic accidents are caused by human related factors. One of the most important human related factor in terms of traffic accident risk is aggressive driving behavior. Although driver aggressiveness is related with psychological reasons, it can be detected by observation of driving behavior using different sensing devices. This work presents a driver aggressiveness detection method exploiting the visual data obtained by on vehicle camera. The proposed method uses this visual data in order to ext...
Development of an expert system for the quantification of fault rates in traffic accidents
Cangul, Eren; Birgönül, Mustafa Talat; Department of Civil Engineering (2010)
Traffic accidents which damage the safety of human beings are one of the most important problems due to their material losses and effects to human health. Although continuous improvements are made by the governments; losses of traffic accidents are still a significant issue all over the world. The usual studies realized so far are generally related with the accident prevention models. However, there has not been much research done concerning the situation after the traffic accidents happen. After occurrence...
