Question

      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. "There're too many cars, and you can't move around a lot. "

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

      He decided to develop a programme called ClearPath for that. He says his program uses historical data to predict traffic conditions even before the driver leaves the house.

        " What's unique is that we  use  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. "

      Professor Shahabi says his system does more than just respond to current traffic conditions. With ClearPath,he says,a driver can decide what time he wants to leave, 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. Professor Shahabi hopes to have  ClearPath available nationwide and overseas once they can collect traffic data  from other cities.

     "I always thought that Los Angeles had the worst traffic, but now I know that Shanghai,Beijing,SeouI,Tokyo, believe it or not, Singapore, Hong Kong certainly are examples that canimmediately use this. "

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