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. [br] We know from the passage that a car can enter a special-purpose lane______.
选项
A、by smoothly merging with cars on the conventional lane
B、by way of a ramp with electronic control devices
C、through a specially guarded gate
D、after all trespassers are identified and removed
答案
B
解析
细节题。根据文章第二段第三、四、五句:“如果使用特殊目的的车道……一种方法是使用特殊的人口引道。当司机接近高速公路入口处时,安装在道边的电子装置会检测车辆的目的地并搞清是否有能工作良好的自动化装置。”故B与此符合,是正确答案。
