Google 緊急通報時に位置情報をより速く正確に通知できる技術をテスト



Googleが2017年12月から2018年1月にかけて、米国内で緊急通報時における同社の位置情報提供技術をテストしました。West Corp.社およびRapidSOS.社と合同で実施しました。テキサス州、テネシー州、フロリダ州内の50のコールセンターおよび240万人の人々が対象。

Wall Street Journalによれば救急措置までの時間が1分短縮されると、1年に約10,000人多くの命を救えるそうです。また、位置情報伝達技術が改善されれば、救助を必要とする人物が英語を話せなかったり、パニックで話せなかったりする場合に、救助隊員の助けになるとのこと。




Google conducts test to help 911 accurately locate callers |

Android phones may soon send more precise location info to 911 dispatchers |






As The Wall Street Journal notes, saving a minute in response times can save up to 10,000 lives a year. Improved location data can also help dispatchers in instances where the caller might not speak English, or in a state of panic, gives the wrong address. “We can validate what the caller is saying,” says Bob Finney III, director of communications for the Collier County Sheriff’s Office in South Florida. “We’ve never been able to do that because it’s never been good enough.”


Google’s location technology is currently available in 14 countries, and the company has said it hopes to bring it to the US this year.

When you call 911 from a cellphone, your location is typically sent to the call taker by a wireless carrier. But that information isn’t always so accurate. Well Google might have a better way of going about it and it tested its system across a few states in December and January, the Wall Street Journal reports. In the states where the tests took place, Google sent location data from a random selection of 911 callers using Android phones straight to the people taking those calls. The test included 50 call centers that cover around 2.4 million people in Texas, Tennessee and Florida, and early reports of the results suggest the system is promising.

One company involved in the test told the Wall Street Journal that for over 80 percent of the 911 calls where Google’s system was used, the tech giant’s location data were more accurate than what wireless carriers provided. The company, RapidSOS, also said that while carrier data location estimates had, on average, a radius of around 522 feet, Google’s data gave estimates with radii around 121 feet. Google’s data also arrived more quickly than carrier data typically did.

This isn’t the first instance where Google has put its location data to use during emergency calls. Last year, the company updated its Phone app so that your location — including your address, a map and latitude and longitude coordinates — are automatically displayed when you call 911.

Google, RapidSOS and another company involved in the trial, West Corp., will reportedly discuss the results of the test at a 911 industry conference this week and Google says it hopes to implement the technology across the US later this year.

Update: An earlier version of this post said Google worked with 50,911 centers, not 50 911 call centers. Our apologies.
