Overview
AUTOMATED
VEHICLES will look similar to conventional manually-operated
vehicles, and with a few exceptions, will be dual mode — designed
to be driven on both conventional roads and
automated roadways. ATS vehicles can be owned privately,
like any other automobile, or leasesd on a per-trp basis.
At
right, shown to scale, are 12 types of vehicles
current automobile manufacturers might be expected to build for
the Automated
Transport
System infrastructure (larger images with descriptions follow
below). All ATS automobiles will have sensors, actuators
and computer systems to fully automate control of the vehicle, as well as controls
to allow driving on existing conventional roads.
To
maximize carrying capacity of the automated roadway and increase
fuel economy, vehicles can
form a cluster. That is, they can
travel bumper to bumper.
For this reason, and to meet other system characteristics,
ATS automobiles
will have fixed-height front dolphin-nose bumpers, concave
rear bumpers
and will
be built along a central backbone (an "I" chassis)
rather
than the conventional "H" chassis, as shown below [details
in the Intermediate
Section.]

One
and two-passenger vehicles
The vehicles shown above are for single passengers (four feet wide)
or two passengers (six feet wide) and weigh
as little as 1,000 pounds. They
could
easily achieve 50 miles per gallon or more with a conventional gasoline engine,
even at sustained high speeds.
Most
cars on our roads today have only one occupant. In fact over
90 percent of miles driven are by single-passenger
vehicles that weigh anywhere from 2,500 pounds to 5,000 pounds.
Moving all this unnecessary weight requires millions of barrels
of gasoline each day. One of the goals of the Automated Transport
System is to reduce the ratio of vehicle weight to occupant weight.
The
single-passenger vehicles shown here can
be owned privately just as any other automobile. But
if a commuter wanted to use one for going to and from work, it
could also be
rented on
a per-trip basis, like a taxi, and cost the passenger something
like 35¢ per mile.
