The document discusses user attitudes towards automated highway systems. It found broad acceptance of safety and warning systems, driver assistance systems, and fully automated highways. Acceptance varied between social groups and the different stages of development. Safety and warning systems, which provide information to drivers about road conditions and potential dangers, were already used by 50% of drivers and found useful, reliable, and good value especially for unfamiliar journeys, at night, and on motorways.
Automated Highway System (AHS) is an example of a large-scale, multi-agent, hybrid dynamical system. In this paper, the use of computer aided simulation tool for design and evaluation of control laws, for an AHS based on platooning, is outlined.

INTELLIGENT TRANSPORTATION SYSTEM(ITS) PRESENTATION Mr. Lucky
It is a brief presentation on the topic of INTELLIGENT TRANSPORTATION SYSTEM(ITS). This is made by final year students of civil branch pursuing their B.tech. from Abdul Kalam Technical University.
In this presentation we try to include the basic methodologies and emerged technologies now a days in transportation system, and also the new concepts of blind turn safety and Spikes on roads at Traffic Signals.
Why it’s Needed?
Traffic congestion-insufficient road development-growing number of vehicles.
Low speed, increased accident rates, increased fuel consumption, and increased pollution.
Impossible to build enough new roads or to meet the demand.
These explore the concepts that treat highway systems and the vehicles that use them as integrated system. Among them is the concept of Intelligent Transportation Systems.
The goal of I T S is to improve the transportation system to make it more efficient and safer by use of information, communications and control technologies.
India is going through a period of drastic change in the transportation area due to:
Rapidly growing economy.
Insufficient and inadequate public transportation system.
Rising vehicle ownership levels.

A highway is any public or private road or other public way on land. It is used for major roads, but also includes other public roads and public tracks: It is not an equivalent term to controlled-access highway, or a translation for autobahn, autoroute, etc.
In North American and Australian English, major roads such as controlled-access highways or arterial roads are often state highways (Canada: provincial highways). Other roads may be designated "county highways" in the US and Ontario. These classifications refer to the level of government (state, provincial, county) that maintains the roadway.
In British English, "highway" is primarily a legal term. Everyday use normally implies roads, while the legal use covers any route or path with a public right of access, including footpaths etc.
The term has led to several related derived terms, including highway system, highway code, highway patrol and highwayman.
The term highway exists in distinction to "waterway".

MANETs by reducing the routing overload and overhead. This proposed routing protocol
additionally extends the battery lifetime of the mobile devices by reducing the specified

Autonomous vehicles: A study of implementation and security IJECEIAES
Autonomous vehicles have been invented to increase the safety of transportation users. These vehicles can sense their environment and make decisions without any external aid to produce an optimal route to reach a destination. Even though the idea sounds futuristic and if implemented successfully, many current issues related to transportation will be solved, care needs to be taken before implementing the solution. This paper will look at the pros and cons of implementation of autonomous vehicles. The vehicles depend highly on the sensors present on the vehicles and any tampering or manipulation of the data generated and transmitted by these can have disastrous consequences, as human lives are at stake here. Various attacks against the different type of sensors on-board an autonomous vehicle are covered.
Taking into consideration the drivers’ state might be a serious challenge for designing new advanced driver
assistance systems. During this paper we present a driver assistance system strongly coupled to the user. Driver
Assistance by Augmented Reality for Intelligent Automotive is an augmented reality interface informed by a several
sensors. Communicating the presence of pedestrians or bicyclists to vehicle drivers may end up in safer interactions
with these vulnerable road users. Advanced knowledge about the presence of these users on the roadway is
particularly important when their presence isn't expected or when these users are out of range of the advanced safety
systems that are becoming a daily feature in vehicles today. For example, having advanced knowledge of a pedestrian
walking along a rural roadway is important to increasing driver awareness through in-vehicle warning messages that
provide an augmented version of the roadway ahead. Voice recognition system through an android platform adds
some good flavour during this project. The strategy of voice recognition through this platform is achieved by
converting the input voice signal into text of string and subsequently it's transmitted to embedded system which
contains an arduino atmega328 microcontroller through Bluetooth as a technique of serial communication between an
android application and a control system. The received text string on an arduino is also displayed on the AR Glass. As
connected vehicles start to enter the market, it's conceivable that when the vehicle sensors detect a pedestrian on a
rural roadway, the pedestrian presence is also communicated to vehicles upstream of the pedestrian location that
haven't reached the destination. This paper presents a survey of studies related to perception and cognitive attention
of drivers when this information is presented on Augmented Reality
Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

2. What is AHS?
An Automated Highway System is a vehicle and road based system that can drive
a vehicle automatically.
This is done using sensors that serve as the vehicle’s eyes,
determining lane position and the speed and location of other vehicles.
Actuators on the throttle, brake, and steering wheel give the vehicle the commands
that a driver normally would.
AHS vehicles often also have equipment to communicate with other AHS
vehicles.
The concept of an Automated Highway has been around for a long time.
General Motors displayed a working model of an automated highway at the 1939
World’s Fair in New York City [8]. Automated trains have been in use since the 1960’s.
But it has not been until recently that the technology has become available to build
Automated highways and vehicles
Picture 4
3. Why Automated Highways?
Safety
Ninety percent of all vehicle accidents result from driver-related factors –
inattentiveness, inability to respond quickly enough, or bad driving decisions [1].
Over 40,000 people die annually in motor vehicle accidents and property
damage is estimated at over $150 billion .
Electronic systems that never take over some or all of the
driver’s responsibilities are the most promising method of reducing these
accidents.
Analyses of causes show that highway accidents could be reduced between 31
and 85
percent with the use of electronic collision avoidance technologies and fatal
crashes
could be reduced by at least 50 percent .
Picture 4
4. AHS was at that time called Intelligent Vehicle-Highway Systems (IVHS).
Falling under the general category of ITS, the stated goals of the system were:
5.Enhancement of surface transportation efficiency
2. Achievement of national transportation safety goals
3. Protection and enhancement of the natural environment and communities affected by
surface transportation
4. Accommodation of the needs of all users of surface transportation systems
5. Improvement of the Nation’s ability to respond to emergencies and natural disasters
Because these goals were so broad, the US Department of Transportation
(USDOT) formed the Joint Program Office (JPO) which brought together the Federal
Highway Administration, Federal Transit Administration, and National Highway Traffic
Safety Administration and several other DOT administrations. From 1992-1994, only
research and analysis on IVHS was done. Engineers mainly worked on human factors
research and traffic safety analysis.
Picture 4
5. History of AHS :
AHS from 1992-94:
In 1991, Congress passed the Intermodal Surface Transportation
Efficiency Act (ISTEA) which introduced funding for many Intelligent
Transportation Systems (ITS).
The Secretary shall develop an automated highway and vehicle
prototype from which future fully automated intelligent vehicle
highway systems can be developed.
Such development shall include research in human factors
to ensure the success of the man-machine relationship .
The goal of this program is to have the first fully automated
roadway or an automated test track in operation by 1997.
This system shall accommodate installation of equipment
in new and existing motor vehicles.
Picture 4
6. Efficiency:
The National highway system carries eighty-nine percent of passenger
groundmiles traveled and thirty-two percent of the ton-miles of commercial
freight travel .
The number of vehicles on the roads has doubled in the last ten years while
highway capacity has for the most part, remained the same.
Consequently, the average speed on urban highways and crowded corridors
during rush hour is 36 miles per hour.
This loss of time and productivity costs the US $50 billion annually .
One solution that engineers are exploring now is an Automated Highway
System (AHS).
By reducing or eliminating driver error and placing cars more closely together
safely on the highways, highway throughput could be doubled or tripled.
Picture 4
7. UK Position on CVHS
The UK is currently considering the role that
Cooperative Vehicle-Highway Systems can play
on its roads.
The Department of Transport, Local Government
& Regions (DTLR), and the Highways Agency,
alongside other UK Agency organisations have set
up a discussion forum to develop policy and
direction in this area.

35. Conclusion :
Without the advantage of increased efficiency through platooning, the only
advantage of using automation in mixed traffic is improved safety.
Although safety is an important improvement, it may not be enough to justify
investment.
The cost/benefit ratio may be too low for government and consumers to
make an investment, especially since the value of added safety is difficult to
measure.
However, mixed traffic intelligent vehicles may be an important first step in
the use of AHS that will lead to the building of more and more dedicated
lanes.
Vehicles should be able to run in either scenario, but perhaps would have
some functions limited while driving in mixed traffic.
