Crash prevention could be a DREAM

01.11.2007
Driving while under the influence of alcohol or drugs, or at speeds significantly above the speed limit are widely considered to be the main causes of serious accidents involving a single vehicle.

However, a new in-depth on-scene study in Sweden reveals that driver fatigue, slippery roads, and inexperience could be just as important and should be factored into the design of new vehicle safety features, according to researchers writing in the International Journal of Vehicle Safety.

Jesper Sandin and Mikael Ljung of the Vehicle Safety Division, at Chalmers University of Technology, in Sweden, used the Driving Reliability and Error Analysis Method (DREAM) to dissect the cause and effect of 38 single vehicle crashes that occurred in Gothenburg. They found that the crashes could be grouped into four scenarios.

In the first scenario, vehicles drifted off road or into the oncoming traffic lane due to driver fatigue, sleepiness or distraction. In the second scenario, a loss of traction caused by an undetected slippery surface caused even experienced drivers to lose control in bends, the researchers explain.

They also found that loss of control in driving around a bend was a factor in the third scenario, but this was due partly to the vehicle's high speed. In this scenario, drivers overestimated their driving skills or had limited experience of the vehicle or the bend and so lost control. In the final scenario, panicked drivers lost control of their vehicle as they tried to steer themselves out of trouble and failed through excessive over steering.

Vehicle safety has improved considerably in recent decades with the development of driver and passenger air-bags, side-impact protection devices, wheel antilocking systems, and traction control for improved cornering. However, single vehicle crashes are very unpredictable with incidence of vehicle rollover and collision with solid objects on the roadside leading to significant injury and fatalities.

"Our study demonstrates a methodology that can be used to explain how a combination of factors may increase the risk of single vehicle crashes," the researchers explain. Such an analysis could allow vehicle manufacturers to design new features that can compensate for the causes described in each of the four crash scenarios. The development of sensors for crash prevention and detection and the activation of safety measures such as airbags and pre-tensioning systems could now take into account the many unpredictable factors involved in single vehicle crashes.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
