科技报道 - 可以预测交通状况的导航应用程序

From VOA Learning English, this is the Technology Report in Special English.


From New Delhi to Beijing, commuters spend a lot of time stuck in traffic. In the United States, Los Angeles and San Francisco tie for second place for having the worst traffic problems. Washington, D.C. is in first place with the worst traffic, according to the Texas A&M Transportation Institute.


In Los Angeles, drivers spend sixty-one hours every year stuck in traffic. These drivers know all too well how bad the traffic can be.


“It’s a prison of cars. There’s too many cars, you can’t move around a lot.”


“I get very frustrated. I try to listen to some music, maybe snap my fingers or something to try to pass the time.”


Professor Cyrus Shahabi also knows about traffic jams. He lives more than 65 kilometers from his office at the University of Southern California, in Los Angeles. He is always late even with the help of a navigation system.

Cyrus Shahabi教授也清楚交通拥堵情况。他住的地方离他在洛杉矶南加州大学的办公室超过了65公里。即使有导航系统的帮助他也总是迟到。

He and PhD student Ugur Demiryurek decided to develop an app for that. The ClearPath app claims to do what other navigation systems cannot. Professor Shahabi says his program uses historical data to predict traffic conditions even before the driver leaves the house.

他和博士生Ugur Demiryurek决定就此开发一个应用程序。这个名为ClearPath的应用程序声称可以做到其它导航系统无法做到的。Shahabi教授说,他的程序使用历史数据在司机离家之前就开始预测交通状况。

"What’s unique is that we utilize a lot of data that’s currently become available including traffic data, weather data, and we analyze that so that we can predict what’s going to happen in front of you when you leave home.”

ClearPath uses two and a half years worth of traffic data from 9,000 sensors on the roads of Los Angeles. It also collects information on accidents.


“Now you are driving and there’s an accident in front of you, but the accident is 20 minutes away. And you know from historical data that that accident would clear by the time you get there. We can take that into account and send you towards the accident because we think by the time you get there, there wouldn’t be any accident.”


Professor Shahabi says his system does more than just respond to current traffic conditions. With ClearPath, he says, a driver can enter what time he wants to leave on a specific time and date, and ClearPath will give the fastest route. It looks at the entire road network, including surface streets as well as highways, before the driver hits the road.


Ugur Demiryurek says they will launch the free ClearPath app for roads in Los Angeles in two months. In a year, he and Professor Shahabi hope to have ClearPath available nationwide and overseas once they can collect traffic data from other cities.

Ugur Demiryurek说,他们将在两个月内推出面向洛杉矶道路的免费ClearPath应用程序。一旦他们能够收集其它城市的交通数据,他和Shahabi教授希望在一年内让ClearPath在国内和海外面世。

“I thought always that L.A. had the worst traffic, but now I know that Shanghai, Beijing, Seoul, Tokyo, believe it or not, Singapore, Hong Kong definitely are examples that can immediately utilize this.”


Professor Shahabi hopes to license this new technology to companies that already have navigation systems, such as Google and Apple.
