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 California, in Los Angeles. He is always late even with the help of a navigation (导航) system.

He decided to develop a program 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 (独特的) 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 leave home.”

Professor Shahabi says his system does more than just answer 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, Seoul, Tokyo, believe it or not, Singapore, Hong Kong certainly are examples that can immediately use this.”Professor Shahabi hopes to share this new technology with companies that already have navigation systems, such as Google and Apple.

When a customer came into a Mexican restaurant in Georgia with an unusual request, a selfless waiter didn’t hesitate(犹豫) to help him out.

A disabled man with no hands who ordered a meal at Cinco cle Mayo Mexican Grill in Douglasville on Sunday afternoon hoped someone might be able to help him eat his lunch.

Server Alex Ruiz, 22, was more than happy to help as he sat opposite from the man and helped him enjoy his meal.

The heartwarming moment was captured in a photo by one of Ruiz’s workmates, Crystal Figueroa. She posted it on the restaurant’s Facebook page.

“He’s a great person,” Figuero, 24, whose father manages the restaurant, said.

“He’s always so nice, and the fact that he just came out of nowhere and helped a man he doesn’t even know have a meal says everything. That just shows the person that he is.

One of Figueroa’s friends, Reginald Widener, also witnessed the moment and posted the photo on his Facebook page.

“This seriously hit me right in the soul,” Widener wrote.

The waiters did not get the name of the man. He had never eaten in the restaurant before, according to Figueroa. But Ruiz jumped at the chance to help.
