Ford develops airbags for seat belts

Inflatable seat belts will appear in the back seat of a new Ford Explorer four-by-four to be launched next autumn in the US, and if they prove to be popular the belts could be used in Britain.

They have a cylindrical air bag that stretches from the buckle to the shoulder and fits inside a pocket sewn into the belt. In a crash, the car sends a signal that releases the bag, which inflates more gently than air bags found in steering wheels or dashboards, making it safer for children.

Dr Srini Sundararajan, the Ford engineer who was chiefly responsible for developing the device, said “The top two life-saving devices today are the seat belt and the air bag. This combines them into one great feature”. The wider belt and airbags help  to spread the forces resulting from a crash across the occupant’s chest, reducing injury risk.

Clarence Ditlow, of the Centre for Auto Safety in the US, said the belts were particularly effective at protecting elderly people, especially from broken ribs.

Ford also carried out a significant amount of testing to make sure the bags would protect children, even if they were sleeping and their heads drooping.

Crash me if you can

Richard Blackburn of the Sydney Morning Herald discusses forthcoming automotive technologies that may bring us closer to "the world's first uncrashable cars". Some of the advanced technologies available now or soon should help drivers to remain stability, stay in lane, avoid low-speed rear-end collisions. Looking further ahead, your car could tell you whether it's safe to overtake or whether you're approaching a corner too fast, help you decide if you have enough time to get across an intersection before the oncoming traffic arrives. You car could even drive itself in a “platoon” formation on the freeway, and automatically avoid pedestrians.

Toyota's product planning manager, Peter Evans, is cautious about predicting dramatic reductions in the road toll in the next decade: you can build an intelligent car but developing intelligent roads and drivers is more of a challenge. "It's that old saying about the nut behind the wheel being the most unreliable part of the car," he says.

The SMH points to intelligent speed adaptation technology being considered by the New South Wales Government in Australia. The technology relies on satellite-linked devices which can read road signs and alert the driver if he or she is speeding. The technology has the potential to actively decrease the flow of fuel to the engine if a car is speeding. Unlike some of the devices being used in the NSW Government trial, a BMW system provides information only. It doesn't intervene to slow the car down. The responsibility for that remains with the driver. 

Meanwhile in Japan, car companies including Toyota and Nissan are working with the Government to develop intelligent freeways. Toyota is about to debut technology that will feed real-time traffic information from roadside sensors into a car's cabin. The technology has the potential to stop minor collisions becoming deadly pile-ups.

Pedestrian friendly cars within sight

According to the Sydney Morning Herald, hundreds of lives could be saved if new pedestrian avoidance technology filters its way in to mainstream cars in the near future. Volvo will soon introduce a car that can automatically apply maximum braking to avoid hitting a pedestrian or reduce injuries. The “Collision Warning with Full Auto Brake and Pedestrian Detection” will arrive in the new S60 in 2010. 

Using a radar and a camera, it can react within 50ms, avoid an impact below 25km/h and reduce speed by 25km/h (at higher speeds). Volvo says its system, also being developed by Audi and Mercedes-Benz, has the potential to reduce injury risk to pedestrians by 83 per cent. 

Software was ‘trained’ after analysing 530,000 kilometres of real world driving to recognise people of all shapes and sizes in thousands of scenarios and even take in to account prams and special clothes. Applying the brakes before a collision is intended to help account for the inattention, which Volvo says contributes to 93 per cent of crashes. “In 47 per cent of crashes the driver doesn’t do anything [brake or steer] before the collision”, said Volvo manager of active safety functions Jonas Tisell.

The SMH warns the hundreds of thousands of kangaroos killed on Australian roads each year not to get too excited. Tisell noted that “The next step is handling animals. But the difficulty with animals is that they are shaped by evolution not to be seen.” Pedestrians will still need their wits about them too. The system may not detect a person stepping out from behind a bus or truck and is unable to detect pedestrians at night. The system is as an iterative step in safety improvement.

The Volvo pedestrian detection system is part of a trend towards crash avoidance rather than vehicle occupant protection. Mercedes-Benz is working on an innovative anchor-like metal and rubber-faced airbag that deploys beneath the car on to the road surface when it detects a collision is imminent.

Human factors 'emerge as trend' in air crashes

Reuters report that Bill Voss, president of the U.S.-based Flight Safety Foundation, has stated that "human factors are emerging as a worrisome trend in global air crashes and other incidents as fatigue, complex flight systems, inconsistent training and regulation pose new challenges to airlines". Voss reportedly told industry and government officials that 2009 could be the worst year in a decade for major commercial aviation accidents. There have been 12 crashes this year through June and carriers globally are on pace to equal the 10-year high of 24 crashes in 1999, according to safety foundation figures. "We've seen an increase in loss of control," Voss said of reported in-flight mishaps linked to turbulence or other unexpected situations that usually do not result in crashes. "We're back in the human factors business," according to Voss. Source: Reuters, 30 June 2009. tinyurl.com/nb255j

Washington Metro crash highlights automation paradox

A collision on the Washington Metro on 22 June killed nine people and injured 76. According to The Washington Post, early indications suggest a computer system may have malfunctioned, and various accounts have raised questions about whether the driver of the speeding train applied the brakes in time. Investigations often focus attention on discrete aspects of machine or human error, whereas the real problem tends to lie in the relationship between humans and their automated systems. "It is easy to focus on the last act that may or may not have prevented the collision," said John D. Lee, professor of industrial and systems engineering at the University of Wisconsin. "But you can trace the accident back to purchasing decisions, maintenance decisions and track layout. To lay the blame on the end result of when and how quickly someone activated the brake may not help with improving safety." Lee pointed out that making automated systems safer leads to a paradox at the heart of all human-machine interactions: "The better you make the automation, the more difficult it is to guard against these catastrophic failures in the future, because the automation becomes more and more powerful, and you rely on it more and more." John Lee is joined by Greg Jamieson and Raja Parasuraman later in the article to acknowledge the consensus that automated systems should be designed to enhance human performance rather than to supplant operators or make them complacent.

Intensive care errors ‘frequent’

Errors in the administration of injected medication occur frequently in intensive care units, a study of 113 units across 27 countries suggests. Over a 24-hour period, 441 patients out of 1,300 were subject to errors, and seven suffered permanent harm. Nearly half of the affected patients suffered more than one mistake. The most frequent errors related to the wrong time of administration and missing doses. Stress, tiredness, recent changes in the drug’s name, poor communication, and protocol violations were cited as contributing factors. Lead researcher Dr Andreas Valentin recommended error reporting systems and routine checks at shift changes. The Intensive Care Society said many units had developed patient safety training programmes, including measures to learn from ‘near misses’. Work was also under way to standardise concentrations of some drugs for critically ill patients, refine the use of antibiotics and minimise the risk of adverse drug reactions.

How to survive a plane crash

Two experts offer some tips. Ed Calea, Professor of mathematical modelling at the University of Greenwich in London: keep your footwear on during climb and descent; sit close to an exit; sit by the aisle; seat your family together; practise releasing your seat belt; know where the exit is; and practise the brace position. According to Amanda Ripley, author of 'The Unthinkable: Who Survives When Disaster Strikes – And Why': take the lead - don't just sit there; listen to the safety briefing; near the exit, take responsibility and prepare to throw the exit door out; educate yourself on why the safety procedures are life-saving; and realise accidents are survivable, and that what you do can make the difference - an active, engaged, confident outlook about your role in the situation is very powerful.

Aviation safety still on course

The Turkish Airlines crash is thankfully a rare occurrence in Europe. The European Aviation and Safety Agency report three in 2007, and six in 2006, with a decade average of six fatal air accidents per year, against a trend of increasing traffic. Only five per cent of worldwide fatal air accidents involved European carriers last year. "Take a million flights and the likelihood of being involved in a fatal accident anywhere in the world is still just 0.79 per cent." Source: Times. http://tinyurl.com/d67tp6

Safety issues cause one-third of deaths in Britain’s military

Ministry of Defence figures obtained by The Independent on Sunday reportedly reveal that nearly 800 service personnel have been killed over 10 years in accidents ranging from car crashes to electric shocks. According to IoS, MoD figures reveal that 201 members of the armed forces died in 2007. Eighty of these deaths were caused by accidents, 50 of them in land transport accidents. The Corporate Manslaughter and Corporate Homicide Act 2007 removes the MoD’s Crown immunity in health and safety matters, leaving senior defence officials open to the same risk of prosecution as employers in the private and public sectors.
