Later next year, Beijing will start the country's first driverless (無人駕駛) subway trains. The Yanfang Line-connecting part of Fangshan district to the city center-will be the first to try out driverless technology.

The Beijing public transportation authority says the new trains will make the metro system better. They will have an upgraded (升級的 ) operating system. They will reach 80km per hour and carry more than l ,200 passengers.

The development of driverless technology is opening up in other areas of transport. Driverless cars have long been a dream for many. And in the past few years，innovation(創(chuàng)新) has speeded up. Big car companies，including Volkswagon and Toyota, are competing with other companies, such as Google.

But with no tracks(軌道)to run on，how will driverless cars be safe? The technology that is used is made up of many sensors (傳感器) ,including radar(雷達) 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，too，like other cars and people.

Pilot-free planes have also become a hot technology topic. Yet while these types of technology are seen as better and safer，they do have disadvantages. Automation(自動化) means these types of transport will heavily rely on computers. Just like humans，they make mistakes-although less often.

And like much1 of technology，it makes many workers lose their jobs. What will happen to the future bus drivers and pilots？
