Autonomous technology has the potential to substantially influence safety, congestion, energy use and ultimately land use.
Conventional driving does not only entail costs for the driver
(e.g. fuel, depreciation, insurance), but also significant external costs,
or “negative externalities” in other people. For example, each additional controller increases congestion for all other controllers and increases the possibility of another driver having an accident. These externalities
they were estimated at around 13 cents per mile. If a hypothetical driver drives 10,000 miles, he charges $ 1,300

possibility of substantially reducing the costs incurred by the driver e

There have been over 5.3 million road traffic accidents in the United States
States in 2011, causing over 2.2 million injuries and 32,000
dead, in addition to billions of dollars in private and social costs. Globally, the figures are much higher.
AV technology can drastically reduce the frequency of accidents.

Effect on mobility
AV technology will also increase the mobility of those who are currently
unable or unwilling to drive. Level 4 AV technology, when the Autonomous vehicle does not require a human driver, would allow transportation of
the blind, the disabled or those too young to drive. The advantages for these
the groups would include independence, reduction of social isolation and
access to essential services. Currently, some of these services are provided by public transport agencies or paratransit, but each of these alternatives has significant disadvantages. Mass transportation generally requires a fixed service

services are expensive because they require a trained and salaried human
driver. Since these costs are generally borne by the taxpayers, in replacement

Effect on traffic congestion and its costs
Level 3 or higher AV technology is likely to decrease substantially
The cost of congestion, borne by the occupants of the Autonomous vehicles

individual AV operators. On the other hand, reductions or increases
In the same congestion there are externalities that will affect all road users.
A reduction in the cost of driving can lead to an increase in the overall Autonomous vehicle

technology can also allow higher performance on roads because

Therefore, the overall effect of AV technology on congestion is uncertain.
As noted above, AV technology of level 3 or higher will likely decline

It could cause people to locate further away from the urban core. Just like him
The emergence of the car led to the emergence of suburbs and suburbs, therefore
The introduction of AV could lead to a more dispersed low density

Effect on energy and emissions
The overall effect of AV technology on energy use and pollution is
uncertain, but it seems likely that both will decrease.
First, AV technology can improve fuel economy by improving it
4–10 percent when accelerating and decelerating more evenly than
A human driver. Further improvements could be achieved by reducing
distance between vehicles and greater road capacity. A platoon
of close AVs that stop or slow down less often look like

actual speeds (improved travel time). Over time, such as the frequency of

would further increase fuel economy
While the futurists have imagined vehicles that drive themselves
decades, research in AV technology can be divided into three phases.
From 1980 to 2003, university research centers
worked on two visions of vehicle automation. The former were automated
road systems where relatively “stupid” vehicles depended on the road
infrastructure to guide them. Other groups worked in AV
It does not require special routes.
Current state of technology
Fully autonomous Google vehicles have enhanced more
500,000 miles without an accident attributable to automation.
Advanced sensors to gather information about the world, more and more
sophisticated algorithms to process sensor data and control the vehicle,
and the computational power to perform them in real time has made this possible
Level of development
In general, robotic systems, including AV, use a “sense of action plan”
design. To detect the environment, AVs use a combination of
sensors, including lidar (light and range detection), radar, cameras,
ultrasound and infrared. A combination of sensors can complement each other and compensate for any weaknesses in any type of
sensor. While robotic systems are very good at collecting data
the environment, making sense of that data is probably the most difficult part of developing an ultra reliable AV.
Role of telematics and communications
The transfer of data to and from moving vehicles should perform a
Important role in AV development in various ways. First, vehicles can use cloud-based resources. For example, AVs can use continuously updated “maps” which are based in part on sensor data from other vehicles. Likewise, if a vehicle’s sensors didn’t work properly, it could be
able to rely in part on the sensors of another vehicle. Second, the federal

Sophisticated infotainment content can occupy the occupants
when it is no longer necessary to drive full time and that this content
can increase the demand for AV technology.
Rules and Regulations
Government regulations and technical standards are political tools used to deal with safety, health, the environment and other public aspects.
Concerns regulations are mandatory requirements developed by policy makers that are specified by law and that the government can apply. The standards, on the contrary, are engineering criteria developed by
technology community that specifies how a product should be designed
or how it should work.
Both standards and regulations will play important roles in
emergency and development of AV technology.
NHTSA is the primary federal security regulator, and generally
promulgates the federal motor vehicle safety standards (FMVSS) that they specify
performance standards for a wide range of safety components, including
Specific crash test performance. NHTSA can also issue withdrawals and influence the market through its new car evaluation program. However, it has no jurisdiction over the operation of cars, vehicle actions
owners, maintenance, repairs or modifications that vehicle owners can make.
Voluntary standards can also play an important role in

methods with which vehicles operate.
Potential effects on traffic congestion costs
Contrary to the remaining uncertainty about the effects of VA on
traffic congestion technology seems almost certain to offer significant results
benefits in terms of reducing costs associated with traffic congestion,
in particular with regards to levels 3 and 4 of automation.
Traffic congestion imposes a variety of social costs, including
waste of time, excessive fuel consumption, greater local air emission
pollutants and greenhouse gases, driver stress, decreased quality of
reduced life and economic efficiency. While many of these costs are
difficult to quantify, it is clear that the total costs associated with congestion are significant.
