Some pessimistic experts feel that the automobile is bound to fall into disuse. They see a day in the not-too-distant future when all autos will be abandoned and allowed to rust. Other authorities, however, think the auto is here to stay. They hold that the car will remain a leading means of urban travel in the foreseeable future.
The motorcar will undoubtedly change significantly over the next 30 years. It would become smaller, safer, and more economical, and would not be powered by the gasoline engine. The car of the future would be far more pollution-free than present types.
Regardless of its power source, the auto in the future will still be the main problem in urban
traffic congestion
. One proposed solution to this problem is the automated highway system.
When the auto enters the highway system, a retractable arm will drop from the auto and make contact with a rail, which is similar to those powering subway trains electrically. Once attached to the rail, the car will become electrically powered from the system, and control of the vehicle will pass to a central computer. The computer will then monitor all of the car’ s movements.
The driver will use a phone to dial instructions about his destination into the system. The computer will calculate the best route, and reserve space for the car all the way to the correct exit from the highway. The driver will then be free to relax and wait for the buzzer that will warn him of his coming exit. It is estimated that an automated highway will be able to handle 10,000 vehicles per hour, compared with the 1,500 to 2,000 vehicles that can be carried by a present-day highway.
The underlined part in the third paragraph means______.
选项
A、traffic jams
B、traffic lights
C、traffic routes
D、traffic regulations
答案
A
解析
词义题。画线单词所在句子的意思是“汽车在未来仍是都市交通 的主要问题”。紧接着,第四段和第五段讲述了如何解决这个问题:将汽车接入自动化高速公路系统,由电脑终端控制,精确计算时间、里程以及交通状况,提升交通效率。由此可以推断出,画线单词的意思是“交通堵塞”,故选A。
