The dangers of drowsy（昏昏欲睡） driving have been widely known. Now several companies have developed face-tracking technology that can tell when drivers become dangerously sleepy.

Here is how it might work. A camera in your car monitors your facial expression, compares it to a database of expressions and determines if you are likely sleepy or distracted. The car then alerts you to pay attention or pull over.

Affectiva has developed emotion recognition technology that aims to detect when people are just starting to get tired. The idea is to catch the warning signs before drowsiness really strikes. “Actually, when someone is drowsy, that is too late.” Gabi, vice president of Affectiva said. “What if you can see trends in someone’s face about five minutes before they become sleepy?” Affectiva’s program can recognize seven different emotions and 15 facial expressions. Its standards were developed by sifting （筛选） through a database of 4 million faces from 75 countries, said Zijderveld. She suggested that carmakers could coordinate （协调）the program’s facial recognition data with oral reminders, such as sound warnings, or （nonverbal）alerts, like a change of temperature and vibrations （continuous slight shaking movements）.

Eyeris is another company working in facial analytics. Modar Alaoui, the company’s CEO, said that its software detects “eye openness” in addition to other facial indicators. The software can also read head position, which may indicate when someone begins to nod off.

These technologies aren’t the first attempt to fight drowsiness behind the wheel. Inventors came up with the similar device “sleeper beeper” to prevent sleep in cars back in 1983. The sleeper beeper was attached to a driver’s ear and would issue a noisy warning when the driver’s head nodded past a certain point. But the latest software would intervene （干涉） earlier and more effectively.

1.The camera in the car can determine if a driver is ________.

A. cold-blooded B. near-sighted

C. bad-tempered D. absent-minded

2.When will drivers be reminded to pay attention or pull over by the face-tracking technology?

A. When they are just beginning to get tired.

B. Five minutes after they become sleepy.

C. When they are really tired.

D. When they are drowsy.

3.It is most likely that the “sleeper beeper” would send out a warning by ________.

A. shaking slightly B. making noise

C. flashing brilliantly D. changing temperature

4.What is the main idea of the text?

A. The dangers of drowsy driving have been widely known.

B. Inventors have tried out the similar device “sleeper beeper”.

C. Several companies have found some ways to fight drowisness behind the wheel.

D. Face-tracking technology for drowsy driving has been developed by several companies.

Controlling traffic is a complex and high cost problem in many developed countries. It becomes more difficult and costly with the ever-increasing number of cars on the roads. But scientists and students at the CATT, at the University of Maryland are working to solve this problem. They are using simulation(模拟) technologies to help government and private business control and react to 　　 changing traffic conditions.

The online economics magazine Forbes.com says traffic congestion(拥挤) cost Americans $ 124 billion in 2014 and that number could rise to $ 186 billion by 2030.

But scientists at the CATT lab are trying to reduce those costs. They are developing a system that helps traffic managers, planners, emergency workers and businesses plan and react better. Michael Pack is CATT director. He says the system is important to help emergency workers, or first responders. reach an accident area faster.

The CATT Lab collects information from many sources, including roadside devices, GPS (global positioning system) equipment and wireless phones.

About 60 students and 30 software developers observe traffic flow and manage the computer servers at all times. They also work to develop software and applications that can help traffic run smoother and safer, Some of them turn the information gathered into so-called "visualizations". These visual representations help emergency workers better understand what is happening.

The center shares its findings with firefighters, police. Transportation departments and the military. They also share information with universities and transportation company.The technology company Google uses the data for its traffic-related websites. Michael Pack says, the information is then shared with anyone who wants to help traffic run more smoothly.

Mr. Pack says the goal is to help develop an intelligent system of road signals that will communicate with each other and with vehicles on the road.
