Stopper: a Ford Taurus is only a few seconds away from crossing the intersection, and suddenly a red light rings on the windshield, warning that another car is approaching quickly at the intersection.
The brakes were quick, and the driver stopped, just as the second car passed a red light and crossed Ford's driveway, the car was previously invisible behind a parked large truck.
The presentation at a recent Transport Conference was a glimpse of the future of car safety: talking to each other and warning drivers of cars that are about to collide.
Later this summer, the government will launch a one-year
In the city of Ontario, Michigan, nearly 3,000 vehicles, trucks and buses using volunteer drivers took part in the world Test.
These vehicles will be equipped with continuous communication on the wireless network, exchanging 10 times per second information about location, direction and speed with other similarly equipped vehicles within about 1,000 feet kilometers.
The computer analyzes the information and sends a danger warning to the driver, usually before they see another car.
On the road today, the Taurus in the demonstration may not --boned’’ —
Was hit by another car.
In 2010, more than 7,800 fatal cross-accidents occurred on American roads. Called vehicle-to-
Vehicle communication, or v2 v, a more advanced version of the system can control the car and prevent accidents by braking when the driver responds too slowly to the warning.
"V2 v" is our next evolutionary step, says David striclandand . . . . . . First of all, make sure that accidents will never happen, and frankly, this is the best security scenario that all of us would like, the director of the National Highway Traffic Safety Administration.
The V2V technology has the potential to help most crashes that have nothing to do with alcohol or drugs, says sitranland.
However, this depends largely on the driver's response to the warning, which is one of the reasons for the Anna Fort test.
Overall, more than 32,000 people died in traffic accidents last year.
In addition to warning the car to run a red light or a parking sign, "connected cars" can also let the driver know if they don't have time to turn left because of oncoming traffic.
When two people were driving
In the driveway, due to the oncoming car, the system will issue a warning when passing --
Even the driver can't see the vehicles around the corners.
In the case of heavy traffic, if a car in front of a few cars has been forced to brake even before the vehicle directly brakes, the system will issue an alarm.
When the driver is in danger of the rear, the system will remind themSlow down. moving car.
If states and communities decide to equip their transportation infrastructure with similar technology, it is also possible for connected cars to exchange information with traffic lights, signs and roads.
This information will be passed on to the traffic management center to keep them away from congestion, accidents or obstacles.
For example, if a car is reported to turn in a position on the road, this may indicate that there are large potholes or obstacles.
A steady stream of vehicles --to-
For example, infrastructure or v2 I information can give traffic managers a better understanding of traffic flow than they do now, so that traffic signals have a better time to keep cars moving.
Accordingly, the car may receive a traffic warning
Ups and rerouting directions ahead.
NHTSA has been working on the technology with eight automakers for the past decade: Ford, GM, Honda, Hyundai-Kia, Mercedes-
Mercedes, Nissan, Toyota and Volkswagen.
"We think this is indeed the future of traffic safety, and it will have a huge impact on our way of life," said Scott Belcher, president of the American Institute of intelligent transportation, the society promotes technical solutions to traffic problems.
Rob Strasberg, vice president of safety at the Automotive Manufacturers Alliance, said the technology is already available.
The government needs to set standards for all automakers to use compatible technologies, he said.
NHTSA officials said that since V2V relies on wireless technology to ensure that the security system is reliable and that it cannot be hacked is another concern.
Unless there are enough cars on the road to talk to each other and do not know where this is, the safety advantage of electric vehicles will not be fully realized.
When the government sets standards and automakers can respond, it may take 10 years for the technology to be widely used in new cars.
It will take about 30 years for a new technology to enter the entire automotive market.
Creating consumer demand for the technology is likely to speed up the rollout, strashangger said.
There is already a need for information about traffic links.
Drivers can download ups and reroute to their smartphones, he said.
Automakers don't like the government asking them to add technology to their cars, but that may be needed, says Clarence dietlow, executive director of the consumer group car safety center.
"If you have this technology and the price has fallen a lot, use it," he said . ".
"Unless you authorize it, you will not put it into the market as soon as possible and will not save as many lives as you can.
"Some of the safety technologies of electric vehicles are already available on the car, although they are mainly provided at a higher level --end models.
For example, a lane departure system warns drivers when their vehicle accidentally deviates from the lane, and some can drive the car back automatically.
The blind spot system warns vehicles in adjacent lanes, and some can avoid danger.
The forward collision warning system reminds the driver that a collision is imminent, and some systems will brake automatically if the driver does not respond.
Adaptive cruise control automatically adjusts the speed and maintains a set distance from the car ahead on the same lane.
Adaptive headlights change their goals with the steering wheel.
Parking sensors and rear
The installed camera can help the driver Park in parallel without scraping paint, bumping a Fender or hitting a pedestrian.
A key difference is that most of the current technologies rely on radar or laser sensors to "see" other vehicles nearby.
They can't warn drivers of cars they can't see, such as cars that run red lights in the intersection demo, or oncoming cars that bypass the road.
Currently available technologies and future V2V systems can effectively form an autopilot for the road.
Strasberg said: "Long
The term trajectory of these technologies is to drive their own vehicles --
