美国之音英语教学，这里是科技报道!
United State officials are close to approving new requirements for enabling vehicles to communicate with each other. Officials hope the new technology will reduce the number of traffic accidents. Automobile manufactures may be required to equip all new cars with what are being called 'vehicle-to-vehicle' communication devices within the next 3 years.
美政府官员即将批准关于汽车之间相互通信的新规定。并希望这项新的技术能减少交通事故的发生。这就要求汽车生产商在未来的三年内将所有的新车上都配备所谓的“车与车”通信设备。
Vehicle-to-vehicle, or V2V, is a communication technology. It enables vehicles to share information about their speed and movement at a rate of 10 times a second. Cars will be able to identify possible dangers within about 300 meters. The cars will then warn their drivers or even take action to avoid in accident.
“车对车”或者简称V2V是一门通信技术。它使得车辆之间可以以每秒10次的频率分享各自的速度和移动信息。汽车在300米之内就能分辨可能存在的危险。然后汽车会警告驾驶员甚至自己采取行动避免发生事故。
The drivers will be able to see, hear and even feel the warning signals through shaking of the seat. The U.S. National Highway Traffic Safety Administration expects the new system to reduce the number of car accidents by as much as 80 percent.
驾驶员通过座椅的摇晃就可以看到，听到甚至感觉到危险信号。美国国家公路交通安全管理局期望通过这个新的系统降低差不多80%的交通事故。
Greg Winfree is with the U.S. Department of Transportation. He says the new technology will change the way people deal with traffic accidents.
Greg Winfree就职于美国交通运输部。他表示这门新的技术将改变人们处理交通事故的方式。
"The way to look at it is the first 50 years of transportation safety were focused on surviving crashes. We see the future as technology that avoids crashes overall," said Winfree.
Winfree说：“在应对交通事故的方式上，头50年的交通运输安全是聚焦于车祸幸存。我们认为未来是通过科技完全避免车祸。”
Critics admit that V2V technology is a major development, but they are concerned about possible conflicts with other wireless devices. They say those devices already operate in the wireless frequencies planned for V2V technology.
评论家们承认V2V技术是一项重大发展，但他们也担心这会与其他的无线设备发生冲突。他们表示那些设备已经在为车对车技术规划的无线频率上运行。
Scott Belcher is the chief operating officer of the group Intelligent Transportation Society of America.
Scott Belcher是美国智能交通协会的首席运营官。
"If somehow we are sharing this spectrum and there's interference and so a car that could have, we could have prevented the crash, we are not able to prevent the crash because someone else is using the spectrum," said Belcher.
Belcher说“如果我们以某种方式共享这一频率就会有干扰。这样我们原本可以防止车祸，却因为有人也在使用这一频率而无法防止车祸。”
Scott Belcher says people may also be concerned about their privacy. He worries about the possibility of using V2V technology to follow individual drivers and document their driving habits. Government agencies and private industry have already invested almost $1 billion in research.
Scott Belcher说人们可能也会担心他们的隐私。他担心有人可能会使用V2V技术跟踪个别驾驶员并记录他们的驾驶习惯。政府机构和私人的企业已经在此项研究上投资了大约10亿美元了!
U.S. officials expect the new technology will be required in American vehicles by early 2017. They believe it is the first step toward a better and safer transportation system.
美官员期待在2017年初此项新技术将装备在美国的车辆上，他们坚信这是朝着更好更安全交通系统迈出的第一步。
