Sports utility vehicles should carry health warnings, say experts

07.10.2005


Editorial: Sports utility vehicles and older pedestrians BMJ Volume 331, pp 787-8



Sports utility vehicles (SUVs) should carry health warnings to raise awareness of the increased risk to pedestrians compared with ordinary cars, argue researchers in this week’s BMJ.

They believe that this should form part of an integrated approach from public health, transportation and road safety agencies to address this growing threat.


Among road users, pedestrians are already a group at high risk, and older people are particularly vulnerable, write experts from Trinity College Dublin. People over 60 are more than four times as likely to die if injured by a car than younger people.

In Europe sales of SUVs have increased by 15% in the past year, while sales of standard cars have dropped by 4%. A recent US study found that, for the same collision speed, the likelihood of a pedestrian fatality is nearly doubled in the event of a collision with a large SUV compared with a passenger car. Other studies report higher rates (up to four times) of severe injury and death.

The increased risk from SUVs arises primarily from the geometry of the front end structure, explain the authors. Pedestrian injuries from cars are mainly leg fractures and knee injuries from the primary impact with the bumper and head injuries from the secondary impact with the bonnet or windscreen.

But because SUV bonnets are higher than those of cars, this results in more severe primary impact on the critical central body regions of the upper leg and pelvis, and a doubling of injuries to vulnerable regions such as the head, thorax, and abdomen.

The evidence clearly shows that SUVs represent a significantly greater hazard to pedestrians than ordinary cars – and those pedestrians are getting older and more vulnerable, say the authors.

Measures to address this threat should include changing crash investigation processes to identify SUVs in vehicle-pedestrian impact statistics, and displaying warning notices on SUVs to help inform consumers of the increased risks.

Addressing the hazards posed by SUVs to pedestrians is an emerging and real traffic safety challenge in the developed world, they conclude.

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Mapping the interaction of a single atom with a single photon may inform design of quantum devices

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
