![How autonomous vehicles work
Autonomous vehicles, otherwise known as uninhabited autonomous vehicles (UAV), autopilot
vehicles, driverless cars, auto-drive cars, or automated/autonomously guided vehicles (AGV),
are regarded as intelligent machines. Alan Turing in his classic 1950 paper, Computing
Machinery and Intelligence , asked “Can Machines Think?”. Of course, this begs the question
of what it means to think. Yet, if we set apart mental activity not done by humans and by an
artificial device but upon which we rely to take action that normally would follow from our
own thoughts, then we have at least some elements of artificial thinking. Recall (memory),
computation, and pattern recognition are activities that can be done better with computers
than by humans, and we traditionally have regarded these as thinking. Navigating a car can
be done entirely by a human thinking but often better by a computer, simply because of the
precision.
A system of systems – design goals
No one component of a system that drives such a vehicle is responsible but a collection of
components.
Since the 1950s rapid
development of
“intelligent systems”
has occurred, including
tire monitoring, human-
machine interfaces,
assisted steering, brake
management,
navigation, and now
semi-autonomous and

Numerous and different
systems have been deployed, giving drivers directions through the global positioning system
(GPS) as to the best routes both audibly and by text [2].

Transit and Highways 2006 (PATH) demonstrated that a row of cars could be driven
automatically down the highway at normal

system work optimally. Drivers may have the choice to override the recommendations of a
car's computer, but such could cause grave complications the integrated system might not be
able to handle, as the change in one component, a car, may well affect how the others will
navigate. Perhaps research from swarm theory will be able to guide us, but at this stage, an
integrated transit control system operates not unlike a packet of information being routed
over a communications network by sophisticated management software or like a power grid,
where one disruption can cause the whole network to go down. How much independence a
driver should have will have to be assessed in such contexts. People may perforce have less
of a choice about being in total charge about where and when they will navigate. We see the
emergence of mesh networks, where cars communicate with each other, much in the same
way people do by walking in crowded spaces, keeping spaced by selecting the most
appropriate routes. For traffic management, it may be a matter of necessity to have a person
entering a crowded area being switched to a network and driven according to the needs
computed by the traffic management software. Such is not much different than an air traffic
control system, where each airliner lands in turn, given the configuration of airport traffic.

How autonomous vehicles work
Autonomous vehicles use various sensors like lasers, radar and cameras combined with systems for navigation, assisted steering, brake management and more to drive without human input. They require coordination between components and other autonomous vehicles to function optimally as part of a larger integrated transportation system. Research is ongoing to develop the necessary technologies and address challenges involving independent decision making versus coordination within the overall system.
