Highway deaths plunging as cars become safer

By Paul A. Eisenstein, msnbc.com contributor
If the numbers in a preliminary federal study hold true, U.S. highway deaths continued to plunge last year – when measured in terms of fatalities per 100 million miles driven - to the lowest level since the government began keeping records in 1921.

A number of factors have contributed to the decline, which has seen traffic deaths dip 25 percent just since 2005. These include better roads and signage and a crackdown on drunk drivers. But another significant factor is the continuing improvement in the safety of the vehicles we drive.

By using the latest in computer-aided design technology, manufacturers have learned how to shield motorists and passengers from the deadly forces of even the most serious crashes. Equally significant are the various high-tech safety devices that are finding their way into the industry’s newest models and which can help motorists avoid accidents in the first place.

“Our research shows that some of the newest forward collision avoidance systems, such as Volvo’s City Safety, are reducing collisions by as much as 20 percent to 30 percent,” said David Zuby, chief research officer for the Insurance Institute for Highway Safety.

The 2013 model year will see some of the most sophisticated systems yet developed – and in many cases technologies once limited to only the most expensive models are migrating down to even entry-level vehicles.

It’s been more than 40 years since federal regulations began mandating improvements in automotive safety, with the seat belt being one of the first devices written into law. In 2011, the National Highway Traffic Safety Administration added electronic stability control – which is designed to keep a car under control on slick surfaces or when it makes an overly aggressive maneuver – to the list. And the NHTSA may soon add rear back-up cameras to the list.

Credit ever faster microprocessors, along with the overall drop in the price of electronic hardware, for making it possible to mandate such technology. But where industry planners routinely resisted new federal regulations in decades past, these days manufacturers are likely to introduce new features – often as standard equipment – without pressure from the government.

“There’s an expectation on the part of customers for more and more safety equipment,” explained General Motors designer Bob Boniface.

The challenge these days, he said is to find a place to put all the various controls and sensors. The front ends of some of GM’s most advanced models. are “covered” with radar and laser sensors, he said, with many new models also introducing advanced video cameras as well.

The latest safety technology roughly divides into two separate categories: active and passive systems. Passive systems are those designed to reduce injuries if an accident occurs. An air bag is such a system. Expect to see some models, such as the 2013 Chevrolet Malibu, offer as many as 10 air bags. The new two-seat Scion iQ microcar is offering the first air bag designed to protect a passenger in the event the vehicle is struck from the rear.

Ford’s is expanding the use of its new inflatable rear seat belts, now found in several models, including the recently redesigned Explorer. According to just-retired Ford safety chief Sue Cischke, the devices are particularly well-suited for use by the very young and the very old because they can suffer internal injuries from the forces acting on standard seat belts in severe collisions.

The 2013 model year will also see a number of new applications of the most advanced active safety systems, which are designed to prevent accidents. A wide range of new mainstream products will add forward collision avoidance, blind-spot monitoring and active lane-keeping. The 2013 Ford Fusion will not only warn drivers that they are drifting out of their lanes but will also help steer the car back into the lane. If the system detects that the driver might also be drowsy, it will sound an alert warning the driver to pull over and rest.

Significantly, many of the most advanced technologies are migrating down-market. Cross-traffic alert was introduced only a few years ago on the redesigned BMW-7 Series. The system, which uses radar to monitor oncoming traffic as a driver backs out of a parking spot, will now be offered on a wide range of midline models, such as the 2013 Nissan Altima.

The redesigned midsized sedan also features blind-spot monitoring, lane departure warning and other systems as part of an optional technology package. The trick, explained Nissan product manager John Curl. was to use a single wide-angle rear camera instead of an assortment of much more expensive radar and sonar sensors.

Subaru will take a similar approach in 2013 with its new EyeSight system, technology it has been tweaking for almost a decade. The system uses a pair of stereoscopic cameras mounted on either side of the rear-view mirror to look out onto the road ahead. It’s a lower-cost alternative, the maker claimed, compared to the radar-based safety systems currently in use by luxury makers such as Mercedes-Benz and BMW.

According to IIHS research, the new technologies are paying off. The basic Mercedes forward collision warning system has reduced accident rates by approximately 6 percent. And the maker has introduced a more advanced version of what it calls Distronic, which can apply the brakes if it senses the driver is not reacting in time to a potential collision.

Cadillac is now working on a prototype system that could also steer a vehicle around an obstacle without a motorist’s involvement. And a number of makers – as well as tech giant Google – are working on fully autonomous vehicles that some proponents believe could be ready for sale before decade’s end.

The good news is that even the features now on the road are saving lives, but IIHS research chief Zuby stressed that because the typical American car remains in use for a decade or longer, it will be close to 2020 before most vehicles in the U.S. fleet have advanced technologies such as electronic stability control, let alone collision warning and blind spot detection.

On the other hand, he added, “As older vehicles retire and these technologies come into a broader segment of the fleet, we can expect to see the death rate continue to decline.”

Hybrids safer than conventional cars, research shows

Hybrids safer than conventional cars, research shows

Yuriko Nakao / Reuters



Prius hybrid vehicles are shown near a Toyota plant in central Japan.


If the fuel-saving benefits weren’t enough, now there’s another good reason for buying a hybrid vehicle instead of a conventional gas-only model.


Research by an affiliate of the Insurance Institute for Highway Safety shows hybrid vehicles are safer than their conventional counterparts when it comes to shielding their occupants from injuries in crashes.


On average, the odds of being injured in a crash are 25 percent lower for people in hybrids than people traveling in comparable non-hybrid vehicles, the research found.


“Weight is a big factor,” said Matt Moore, vice president of the Highway Loss Data Institute and an author of the report. “Hybrids on average are 10 percent heavier than their standard counterparts. This extra mass gives them an advantage in crashes that their conventional twins don’t have.”


Hybrid cars are heavier than cars that only use an internal combustion engine because they have large, heavy batteries and two engines. They save on fuel by storing the energy produced when braking and using it to power the vehicle at low speeds.


Moore points to other possible factors for the better safety record for hybrid vehicles, such as how, when and by whom hybrids are driven. Researchers said they included controls to account for these factors.


The study estimated the odds that a crash would result in injuries if people were riding in a hybrid vs. the conventional version of the same vehicle. The analysis used data from more than 25 hybrid-conventional vehicle pairs from the 2003-11 model years.


The study’s findings are good news for green-minded drivers who are also looking for safety in their cars. But it’s worth noting that hybrid vehicles still pose a risk to pedestrians.


At low speeds in densely built areas, hybrid cars and pure electric vehicles rely on electric propulsion. That makes them much quieter than gas-powered cars, posing a risk to pedestrians.


A 2009 report by the National Highway Traffic Safety Administration found a higher rate of pedestrian crashes for hybrids than for conventional gas-powered cars, especially when the vehicles were turning.

SUVs now safer in crash; small cars risky

SUV are driver now among the least likely in a car accident die according to new findings released Thursday by the Insurance Institute for highway safety (IIHS). Major retailers like Wal-Mart are thinking the country's most prominent retail giant, target and Wal-Mart small, smaller versions of their familiar mega stores test. Life Inc.: Beloved you your family enough, to work more? Many see in difficult times, night shift in a new Licht life Inc.: fathers have also occupation issues

The change is largely to the widespread availability of electronic stability control (ESC), which to prevent rollover. With the tendency to reduced roll over SUVs are safer than cars, to balance because their larger size and weight offer better protection in a crash, the IIHS said.

"The risk of rollover in SUVs used their size/weight advantage prevail, but that is no longer the case, thanks to ESC," said Anne McCartt, Senior Vice President of the Institute for research.

When driver death rates by vehicle style are considered, minivans deaths per million registered vehicles have the best results with a mortality rate of 25 riders, the insurance industry funded security group found. SUVs are not far behind with 28, and pickup trucks on average 52 driver deaths. Cars have a mortality rate of 56, but smaller cars with fare worse than larger, 4-door motor coaches show a mortality rate of 82, compared to 46 for very large 4-door vehicles.

The IIHS analysis driver death rates measured from 2006 to 2009, for the years 2005-8 model. A general death rate registered 48 deaths per million vehicles found during this period.

It is not only weight, which gives the advantage of SUVs. It is also the height of the vehicle and other factors. When compared to cars and SUV's of similar weight, the SUVs have lower death rates, which said IIHS.

Always safer, insurance group says small cars

DETROIT - small cars are safer than more models than ever that deserve top always crash tests from the insurance industry.

The Insurance Institute for highway safety Thursday, that 6 of the 13 small cars it last tested top safety picks are. Focus and Honda Civic and the 2011 include the 2012 Ford Hyundai Elantra, Nissan Juke Lexus CT 200 h and Toyota Prius.

If these cars are combined with other previously tested - including the electric Nissan leaf and Chevrolet deserves Volt - a total 22 the Institute top score.

This is a big change from model year 2006, when top safety rating, earned only three small cars even though this review was less strict than it is today. In 1997, when the Institute first small cars over a 40-mile per hour frontal test laid, none of the 11 earns a top rating.

"Every time we have introduced a new test automakers have intensified and improved designs,", David Zuby, the Institute said chief research officer. Zuby said that companies stronger materials and better design to use the power of crashes from manage.

A top safety pick, cars have the highest rating in frontal - earn - and back side-impact of crash tests and check roof. You need to prevent electronic stability control as an available option to rollover accidents.

The strength test of roof that simulates what would happen to the roof when the car rolled over, stumbled to several cars in this round of testing. The 2011 Honda CR-Z, Honda insight, Nissan versa, Nissan Sentra, Suzuki SX4 and Dodge Caliber has lower ratings for roof strength. Scion xD got a lower rating in the frontal crash test.

Zuby said that the Hyundai Elantra performance shows how much vehicle design has improved. In 2001, the Elantra received the lowest scores for frontal impact protection. Among his problems was the air bag deployed late. Until 2006 it was still bad, the lowest score in the side crash test, earn working although it side airbags. But the Elantra 2011, which went on sale a few months ago, aced every test and now has standard stability control.

Zuby warned that larger and heavier vehicles are inmates protect always better than small. He said, that is, why it is particularly important for manufacturers to make small cars such as crash-proof as possible.
