Whiplash injuries as a result of rear impact are among the most common injuries in traffic accidents. This is why whiplash injuries have reached a high priority in the research area. In this study, the effects of head restraint position and impact pulse to the whiplash injury have been analyzed by performing whiplash tests using the sled test facility of METU-BILTIR Center Vehicle Safety Unit. Although there are many whiplash test protocols, the test sample has been prepared according to the most recent one, Euro NCAP Whiplash Test Protocol. Three different head restraint positions and three different impact pulses with different severities, totally nine tests have been performed. The tests are performed with a three point generic seat belt and an instrumented Hybrid III 50th percentile male adult crash test dummy is used as the occupant in driver seat of a light commercial vehicle. High speed cameras, sensors on the crash test dummy and a data acquisition system are used to take the test data. This test data has been analyzed and presented according to the defined whiplash assessment criteria and the performance scores of the particular seat for each test have been determined using the whiplash assessment criteria values according to the Euro NCAP Test Protocols.

Neck injuries frequently seen in low-speed rear-end collisions are referred to as whiplash injuries. Most of the proposed anti-whiplash systems in the literature rely on reducing the backset. A relatively new and promising alternative concept is a slideable seat. This study aimed to parametrically analyze an anti-whiplash vehicle seat that can slide backward against a horizontal suspension arrangement composed of a spring and a damper in response to a rear-end collision, and to investigate the effects of th...
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...
Design and simulation of an ABS for an integrated active safety system for road vehicles
Şahin, Murat; Ünlüsoy, Yavuz Samim; Department of Mechanical Engineering (2007)
Active safety systems for road vehicles have been improved considerably in recent years along with technological advances and the increasing demand for road safety. In the development route of active safety systems which started with introduction of digital controlled ABS in the late seventies, vehicle stability control systems have been developed which today, with an integration approach, incorporate ABS and other previously developed active safety technologies. ABS, as a main part of this new structure, s...
Experimental and numerical investigation of comparability of whiplash sled test results
ÖZDEMİR, MUSTAFA; İDER, SITKI KEMAL; Gökler, Mustafa İlhan (2016-02-01)
Whiplash-associated neck injuries represent an important health and socioeconomic problem attracting more and more attention of the vehicle safety community. Sled tests are conducted for the dynamic whiplash assessment of seats. However, reproducibility of the initial backset distances and of the sled pulses in every test plays an important role on the comparability of these results. In this study, in order to investigate these aspects, three different driver seat types are considered with three identical a...
A comparison of roadside design approaches in terms of road safety to improve Turkish roadside safety standards
Betus, Yakup; Tüydeş Yaman, Hediye; Department of Civil Engineering (2022-5-31)
When an errant vehicle runs off the road, crashing into objects/ reaching places in the vicinity creates “run-off-road (ROR)” accidents, which may result in severe injuries or fatalities. Roadside designs with proper Road Restraint Systems (RRS) ideally should cause neither hazards to the third parties nor threats to the vehicle users. The major components of the RRSs are the Vehicle Restraint Systems (VRS), including the safety barriers (i.e., guardrails) designed to i) either stop the errant vehicle fully...
