Question

Later this year, Beijing will start the country’s first driverless(无人驾驶 ) subway trains. The Yanfang Line-connecting part of Fangshan district center-will be the first to try out driverless technology.

According to the experts(专家) in public transportation, the new trains will make the underground railway system(系统) better. They will have an upgraded(升级的)operating system. They will reach 80km per hour and carry more than 1,200 passengers.

The development of driverless technology is opening up in other areas of transport(交通工具). Driverless cars have been a dream for many people. And in the past few years, big car companies, including Volkswagen and Toyota, have made lots of studies while they are competing with other companies, such as Google.

But with not racks(轨道) to run on, how will driverless cars be safe? This technology is made up of many sensors(传感器) including radar and GPS. This gives the car an exact position in the world, as well as what’s around it. It also allows the car to see moving objects(目标), like other cars and people.

Pilot-free planes have also become a hot technology topic. Yet while these new kinds of technology are seen as better and safer, they do have problems. They cannot work at all without the help of computers. Just like humans, computers make mistakes-although less often. And like much of technology, it makes many workers lose their jobs. What will happen to the future bus drivers and pilots?
