VOA慢速英語:如果車與車可以相互交談那么大部分交通事故就可以避免

[00:00.00]From VOA Learning English, [00:02.77]this is the Technology Report. [00:05.51]United State officials are close to approving [00:09.61]new requirements for enabling vehicles [00:13.14]to communicate with each other. [00:15.26]Officials hope the new technology [00:18.60]will reduce the number of traffic accidents. [00:22.59]Automobile manufactures may be required [00:26.75]to equip all new cars [00:29.08]with what are being called [00:31.24]'vehicle-to-vehicle' communication devices [00:34.14]within the next 3 years. [00:37.37]Vehicle-to-vehicle, or V2V, [00:41.23]is a communication technology. [00:44.17]It enables vehicles to share information [00:47.16]about their speed and movement at a rate of 10 times a second. [00:53.15]Cars will be able to identify possible dangers [00:56.88]within about 300 meters. [00:59.56]The cars will then warn their drivers [01:02.39]or even take action to avoid in accident. [01:06.08]The drivers will be able to see, [01:09.92]hear and even feel the warning signals [01:13.74]through shaking of the seat. [01:16.22]The U.S. National Highway Traffic Safety Administration [01:21.30]expects the new system to reduce the number of car accidents [01:26.24]by as much as 80 percent. [01:29.29]Greg Winfree is with the U.S. Department of Transportation. [01:34.77]He says the new technology will change the way [01:38.77]people deal with traffic accidents. [01:41.71]"The way to look at it is the first 50 years [01:43.71]of transportation safety were focused on surviving crashes. [01:48.29]We see the future as technology that avoids crashes overall," said Winfree. [01:53.08]Critics admit that V2V technology is a major development, [01:59.44]but they are concerned about possible conflicts [02:03.68]with other wireless devices. [02:06.24]They say those devices already operate [02:10.03]in the wireless frequencies planned for V2V technology. [02:15.41]Scott Belcher is the chief operating officer [02:19.26]of the group Intelligent Transportation Society of America. [02:23.92]"If somehow we are sharing this spectrum and there's interference [02:29.10]and so a car that could have, we could have prevented the crash, [02:33.54]we are not able to prevent the crash [02:35.43]because someone else is using the spectrum," said Belcher. [02:38.13]Scott Belcher says people may also be concerned about their privacy. [02:43.92]He worries about the possibility of using V2V technology [02:48.98]to follow individual drivers and document their driving habits. [02:54.55]Government agencies and private industry [02:58.63]have already invested almost $1 billion in research. [03:04.17]U.S. officials expect the new technology [03:08.36]will be required in American vehicles by early 2017. [03:13.90]They believe it is the first step [03:16.85]toward a better and safer transportation system. [03:21.14]And that's the VOA Learning English Technology Report.
