What might driving on an automated highway be like? The answer depends on what kind of system is ultimately adopted. Two distinct types are on the drawing board. The first is a special-purpose lane system, in which certain lanes are reserved for automated vehicles. The second is a mixed traffic system; fully automated vehicles would share the road with partially automated or manual driven cars. A special-purpose lane system would require more extensive physical modifications to existing highways, but it promises the greatest gains in freeway (高速公路) capacity.
Under either scheme, the driver would specify the desired destination, furnishing this information to a computer in the car at the beginning of the trip or perhaps just before reaching the automated highway. If a mixed traffic system way was in place, automated driving could begin whenever the driver was on suitably equipped roads. If special-purpose lanes were available, the car could enter them and join existing traffic in two different ways. One method would use a special onramp (入口引道). As the driver approached the point of entry for the highway, devices installed on the roadside would electronically check the vehicle to determine its destination and to ascertain that it had the proper automation equipment in good working order. Assuming it passed such tests, the driver would then be guided through a gate and toward an automated lane. In this case, the transition from manual to automated control would take place on the entrance ramp. An alternative technique could employ conventional lanes, which would be shared by automated and regular vehicles. The driver would steer onto the highway and move in normal fashion to a "transition" lane. The vehicle would then shift under computer control onto a lane reserved for automated traffic. [The limitation of these lanes to automated traffic would, presumably, be well respected, because all trespassers (非法进入者) could be swiftly identified by authorities. ]
Either approach to joining a lane of automated traffic would harmonize the movement of newly entering vehicles with those already traveling. Automatic control here should allow for smooth merging without the usual uncertainties and potential for accidents. And once a vehicle had settled into automated travel, the driver would be free to release the wheel, open the morning paper or just relax.
Which of the following is true about driving on an automated highway?
选项
A、Vehicles traveling on it are assigned different lanes according to their destinations.
B、A car can join existing traffic any time in a mixed lane system.
C、The driver should inform his car computer of his destination before driving onto it.
D、The driver should share the automated lane with those of regular vehicles.
答案
C
解析
是非题。根据第二段第一句:Under either scheme,the driver would specify the desired destination,furnishing this information to a computer in the car at the beginning of the trip or perhaps just before reaching the automated highway.不论采用哪种设计,司机都需要在其开始行驶时或在到达自动化高速公路前确定要去的目的地,把这个信息输入车上的计算机。故C是正确答案。选项B与文章内容相悖,因为原文第二段第二句是on suitably equipped roads而不是existing traffic。选项D提到的情况只适用于第二种设计方案,即混合式交通系统。故A、B、D均不是正确答案。
