system is ultimately adopted. (47) 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 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.
(48) As the driver approached the point of entry for the
highway, devices installed on the roadside would electronically check the
vehicle to determine it 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. (49) 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. (50)
. A. An alternative technique could employ
conventional lanes, which would be shared by automated and regular
vehicles. B. Vehicles traveling on it are assigned
different lanes according to their destinations. C. 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.
D. What might driving on an automated highway be like
E. One method would use a special onramp(入口引道). F.
Two distinct types are on the drawing board.
