New research could lead to a significant decrease in fatal road injuries to pedestrians and cyclists

30.09.2004


Research carried out by scientists at the University of Surrey could lead to a significant decrease in the number of pedestrians and cyclists killed each year on Europe’s roads. In-car systems have significantly improved safety for drivers and passengers, and the introduction of soft bumpers and pop-up bonnets has lowered the risk of injury to pedestrians and cyclists, but a system of new sensors currently being developed, could potentially lower the fatality rate even further.



Over 6000 pedestrians and cyclists (Vulnerable Road Users – VRUs) are killed annually on EU roads, this is approximately 25% of all road deaths. In the UK 71% of VRU fatalities occurred at impact speeds under 40mph and 85% of fatalities were injured by the front of the vehicle involved. Deploying external airbags at the front of vehicles could reduce these figures significantly, but a sensor system must be developed to ensure correct and safe deployment.

Scientists believe that a system combining new infrared thermal sensing technology with a high resolution radar could be the answer, since the combination distinguishes VRUs through body heat and not body shape. The system would be able to sense walking adults and children as well as wheelchair users and babies in buggies, as it is not reliant on recognising a pre-set ‘human’ shape but the body heat of the individual. This would then enable the radar system to track the subject and deploy a safety system just before impact. Trials have already taken place using a new. advanced ‘crash test dummy’, which not only has the usual physical properties of such dummies, but also has a human-like heat image.


Dr Eddie Moxey leader of the research at the University of Surrey comments: ‘While we have demonstrated that we can design a sensor system capable of detecting and reacting to a collision with a pedestrian, further development of the safety systems is required before such systems become a commercial reality. Automatically applying the vehicle’s brakes to slow the car down is likely to be best practical approach for the first commercial system. The use of airbags is likely to take a little longer, but at least we have made a start.’

Dr Nicola Christie, a leading researcher on child road traffic safety also based at the University said that ‘ road traffic accidents are a major cause of premature death across Europe. Any secondary safety measures, such as these could minimise the severity of injuries among pedestrian and bicyclist casualties and reduce the burden of injury to the individual and society as a whole’.

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,...
