An automated highway system (AHS) or Smart Road is a proposed intelligent transportation system technology designed to provide for driverless cars on specific rights-of-way. It is most often touted as a means of traffic congestion relief, since it drastically reduces following distances and thus allows more cars to occupy a given stretch of road.
Every major city suffers from the problems that are related to increasing mobility demands. Cities have to deal with pollution, congestion and safety problems caused by increasing traffic. Traditional transport systems are not sufficient anymore to cope with these increasing problems.
With the exception of some automatically operated metro systems (Paris, London and Lille) and some recently introduced automated buses and people-movers (Clermont-Ferrand, Eindhoven and Capelle aan de IJssel), transport systems in the present-day European city are mostly of a traditional type.
automated highway system will contribute to innovative solutions that will allow increased mobility in a well-controlled manner, using technologies with low pollution, high safety levels and a much increased efficiency, using either a separate infrastructure or existing roads. In future mobility scenarios, such new transport systems will be part of the urban environment. These new transport systems will be the answer to the new mobility demands of the future society. In our vision, the urban mobility will be greatly supported by new transport system concepts, which are able to improve the efficiency of road transport in dense areas while at the same time help to reach the zero accident target and minimize nuisances.

In an automated highway system, the car will be out by the road rather than the driver. Connect sensors and communication devices the road and the vehicle is to maximize performance. Driver error can be reduced and eventually eliminated with full implementation.

The history of the automated highway system goes back to a working model that was displayed at the 1939 World Fair's General Motors Pavillion. During the 1950s and 1960s, researchers at General Motors refined driverless vehicles, including robotic trucks. In the late 1960s and early 1970s, Robert Fenton of Ohio State University demonstrated driverless cars on a test track. Although the test was successful, the early results were crude and hardly workable.
By the late 1980s, advances in microprocessors, wireless communications and other electronic sensors prompted a renewed interest in the automated highway, leading to the formation of the Intelligent Transportation Society of America in 1988, whose goal was to foster the introduction of automated highways. In 1991, Congress called for a prototype system and the National Automated Highway System Consortium (NAHSC) was formed. The NAHSC is a public-private partnership composed of approximately 1,000 members representing federal government agencies, vehicle industry, state/local government agencies, highway design industry, vehicle electronics industry, environmental interest groups, trucking operators, transit operators, transportation users, and the insurance industry.
 The AHS program is a broad international effort “to provide the basis for, and transition to, the next major performance upgrade of the vehicle/highway system through the use of automated vehicle control technology.”
 The term “fully automated intelligent vehicle-highway system” is interpreted to mean a system that:
1. Evolves from today’s roads.
2. Fully automated
3. Operate in both urban and rural areas on highways
A five-layered architecture consisting of a network, link, planning, regulation and physical layers is proposed in for the development of AHS
Network : Control entering traffic and route traffic flow
within AHS network.
Link : Compute and broadcast activity plans.
Planning : Communicate and coordinate with peers and select one maneuver to be executed.
Regulation : Execute maneuvers such as join, split, lane change.Physical : Decouple lateral and longitudinal control.
Working of automated highway
With magnetometer sensors mounted in the front and rear bumpers,
vehicles are guided by a track of magnets planted in the pavement. The
magnets are about an inch in diameter and are embedded into the
pavement at the center of each lane. The magnets feed information
about the upcoming road, such as curves, merge lanes, or exits, to an
on-board computer for analysis. In a millisecond, the computer
determines the car's precise location in the lane and communicates to
the steering actuators which way to guide the car. To keep a safe speed
and traveling distance between vehicles, highly sensitive radar sensors
are used to locate the positions of other vehicles on the road. These
radar sensors communicate with the on-board computer, which then
controls the brakes and throttle to maintain the right speed and
distance. After exiting the Automated Highway, you'll take back control
of your vehicle on the surface roads.

Automated Highway Systems

A major long-term element of Intelligent Transportation Systems research and development is
Automated highway Systems (AHS). The AHS program is a broad international effort “to
provide the basis for, and transition to, the next major performance upgrade of the
vehicle/highway system through the use of automated vehicle control technology” [NAHSC96].
The detailed definition of the Automated Highway System is as follows [Plan93]:
The term “fully automated intelligent vehicle-highway system” is interpreted to
mean a system that:
w Evolves from today’s roads (beginning in selected corridors);
w Provides fully automated “hands-off” operation at better levels of performance
than today’s roadways in terms of safety, efficiency, and operator comfort; and,
w Allows equipped vehicles to operate in both urban and rural areas on highways
that are both instrumented, and not instrumented.
The consensus in the AHS community is that AHS will evolve over a series of smaller
steps in technology. The final step of full automation will not be a leap, but a logical consequence
of previous development and deployment efforts. Each step in the technology will have its own
benefits and be self-sustaining. Vehicle and infrastructure evolutions will be “synchronous”
[James94]. We will briefly mention the steps of this evolution here before introducing the AHS
program and discussing automatic vehicle control technologies in detail.

AHS Program Phases and the National Automated Highway
Systems Consortium

The AHS program in United States is planned around three broad phases: Analysis
(1993-96), System Definition (1994-2001), and Operational Tests and Evaluation (starting in
2001). The National Automated Highway System consortium (NAHSC) is responsible for
conducting the second phase.

Vehicle Control
Vehicle control is probably the most important part of the advanced AHS applications.
Implementation of AHS necessitates automatically controlled vehicles as mentioned previously.
Achieving the optimal solution to congestion and safety problems requires extensive research in
system modeling, lateral (steering) controls and longitudinal (speed and headway) controls. In a
fully automated highway system, these control systems will rely on vehicle-to-vehicle
communication, as information on velocity and acceleration of other vehicles will be utilized in
individual vehicle controllers [Varaiya93]. The same information and much more (e.g., desired
speed and lane) may also be received via vehicle-to-roadside communications. Here, we will
briefly discuss the previous research on lateral, longitudinal and combined lateral and longitudinal
control of vehicles.

Longitudinal Control
Longitudinal control is an important aspect of the future AHS. One of the major concepts in this
area is platooning, which is a formation of traveling vehicles that maintain close spacing at
highway speeds. The concept requires inter-vehicle communication links to provide velocity and
possibly acceleration information from the lead vehicle to each of the following vehicles, as well
as the velocity and acceleration of the preceding vehicle in the platoon.

A Simulation Tool for AHS Systems: DYNAVIMTS
During the last few years, many computer programs for microscopic and macroscopic level
simulations of vehicles in an automated system have surfaced. Paramics (Parallel Microscopic
Simulation) is currently used to find the reasons for large-scale congestions in the Controlled
Motorway pilot project and implimentation on the M25 highway in England, by dividing the the network into a
number of regions [Duncan96, Cameron96]. DYNAVIS is another dynamic visualization package
specifically designed for evaluating automatic control of vehicles [Xu96].
