Proposed smart traffic signal control in brunei darussalamAndino Maseleno
This paper presents proposed SMART (Systematic Monitoring of Arterial Road Traffic Signals)
traffic signal control in Brunei Darussalam. Traffic congestion due to stops and delays at traffic light signals
has much been complained about in Brunei Darussalam as well as across the world during the recent years.
There are primarily two types of traffic signal controls in Brunei Darussalam. The most common one is
the fixed or pre-timed signal operation traffic light and the other one is the actuated signal operation traffic
light. Although the actuated signal control is more efficient than the fixed or pre-fixed signal control in the
sense that it provides fewer stops and delays to traffic on the major arteries, the best option for Brunei
Darussalam would be to introduce SMART traffic signal control. This type of traffic signal uses artificial
intelligence to take the appropriate action by adjusting the times in real time to minimise the delay in the
intersection while also coordinating with intersections in the neighbourhood. SMART signal simultaneously
collects event-based high-resolution traffic data from multiple intersections and generates real-time signal
performance measures, including arterial travel time, number of stops, queue length, intersection delay, and
level of service. In Brunei Darussalam, where we have numerous intersections where several arterial roads
are linked to one another, The SMART traffic signal control method should be implemented.

Vehicle density sensor system to manage trafficeSAT Journals
Abstract The aim of this study is to solve traffic congestion which is a severe problem in many modern cities all over the world. To solve this problem, we have a framework for a dynamic and automatic traffic light control system. Generally, each traffic light on an intersection is assigned a constant green signal time. It is possible to propose a dynamic time-based coordination schemes where the green signal time of the traffic lights is assigned based on the present conditions of the traffic. In this study, we adapt the approach to take data/input/image from object/ subject/vehicle and to process the input data by Computer and Microcontroller and finally display it on the traffic light signal to control the Closed Loop System.

· Traffic Control and Analysis at Signalized Intersections
Signals offer the maximum degree of control at intersections. They relay messages of both what to do and what not to do. The primary function of any traffic signal is to assign right of way to conflicting movements of traffic at an intersection, and it does this by permitting conflicting streams of traffic to share the same intersection by means of time separation.
By alternately assigning right of way to various traffic movements, signals provide for the orderly movement of conflicting flows. They may interrupt extremely heavy flows to permit the crossing of minor movements that could not otherwise move safely through the intersection.
When properly timed, traffic signals increase the traffic handling capacity of an intersection, and when installed under conditions that justify its use, it is a valuable device for improving the safety and efficiency of both pedestrian and vehicular traffic. In particular, signals may reduce certain types of accidents, most notably the angle (broadside) collision.
Green time. The amount of time within a cycle for which a movement or combination of movements receives a green indication (the illumination of a signal lens). This is expressed in seconds and given the symbol G.
Yellow time. The amount of time within a cycle for which a movement or combination of movements receives a yellow indication. This is expressed in seconds and given the symbol Y. This time is referred to as the change interval, as it alerts drivers that the signal indication is about to change from green to red.
Red time. The amount of time within a cycle for which a movement or combination of movements receives a red indication. This is expressed in seconds and given the symbol R.
All-red time. The time within a cycle in which all approaches have a red indication (expressed in seconds and given the symbol AR). This time is referred to as the clearance interval, because it allows vehicles that might have entered at the end of the yellow interval to clear the intersection before the green phase starts for the next conflicting movement(s). This type of interval is becoming increasingly common for safety reasons because the rate of vehicles entering at the end of the yellow and beginning of the red indication has steadily increased in recent years.
Pretimed. A signal whose timing (cycle length, green time, etc.) is fixed over specified time periods and does not change in response to changes in traffic flow at the intersection. No vehicle detection is necessary with this mode of operation.
Semi-actuated. A signal whose timing (cycle length, green time, etc.) is affected when vehicles are detected (by video, pavement-embedded inductance loop detectors, etc.) on some, but not all, approaches. This mode of operation is usually found where a low-volume road intersects a high- volume road, often referred to as the minor and major street ...

Abstract
The project is to make a prototype which shows a successful implementation of a Field Programmable Gate Array (FPGA) CAN bus monitor for use in a traffic signal where a traffic junction (node) can operate in three modes namely, normal mode, priority mode, the ambulance mode and also to develop an Android application to make a traffic density in each node available to the user. The traffic density along the roads are sensed using an array of IR sensor’s interruption, connecting sensors to the traffic signal controller. The CAN bus is used for the communication between Traffic signal controller (nodes). In priority mode, giving priority to the most populated side of the road and in ambulance mode, paving way for the emerging ambulance resetting the current side according to the instruction sent to the controller from the main server via GSM module (in ambulance) according to the GPS co-ordinates of the ambulance marked by the main server to the path of the hospital. The traffic densities are periodically updated in the main server. The Android application is developed from the information in the main server, to make it available to the user. The nodes can be increased to N number extending the CAN bus linking the successive traffic junctions at differen
good communication system is very for the following purposes:
1-Synchronization of controller timer at each intersection for offset implementation.
2-Exchange of traffic data between controllers.
3-Malfunction reporting from each controller to the control room.
4-Incident reporting to the control room.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

2. TRAFFIC SIGNALS:
Traffic signals are controlled devices which could alternatively
direct the traffic to stop and proceed at intersection using red
and green traffic light signals automatically.
3. Purpose of Traffic Signals
Traffic signals manage the right of way at signalized intersections to
provide for the safe and efficient movement of vehicles and pedestrians.
Traffic engineers and technicians develop and implement signal timing
at each intersection to distribute green time amongst the competing
traffic flows to provide for efficient operations.
4. NEED OF TRAFFIC SIGNALS
•Orderly flow of traffic.
•An opportunity for pedestrians or
vehicles to cross an intersection.
•Help reduce the number of conflicts.
•Reduce the frequency of accidents.
•Improve safety.
7. Traffic Signals : Advantages
• Provisions for side-street vehicles to enter the traffic stream.
• Provisions for the progressive flow of traffic in a signal-system corridor.
•Provisions for pedestrians to cross the street safely.
•Potential reduction of accidents, conflicts ensuring safety.
8. Traffic Signals : Disadvantages
• Excessive delay;
• Increased traffic congestion, air pollution and gasoline consumption;
•Disobedience of signals;
•Increased frequency of crashes, especially rear-end collisions.
9. Parts of a Traffic Signal
• Traffic signals have four main parts:
Display Controller
Detector Support
10. Signal display
The signal display is what the driver sees. A simple signal display
consists of three colors: red, yellow, and green.
• A typical signal display is more than 3 feet tall and weighs up to 50
pounds.
11. Signal Controller
The traffic signal controller is the “brain” at an intersection that tells each
signal display when to change colors. Years ago, traffic signals were
controlled by a simple electric mechanism that made the display change every
so many seconds, like a clock. These simple mechanisms were not able to
adjust when traffic changed during the day.
Later in the pre-computer era, electromechanical controllers were developed
that could be adjusted for the time of day. These controllers were much like
the switch timers in the local hardware store that have green and red pins to
set lights to go on and off on a predetermined schedule.
12. CONTINUE…………
Now, computerized traffic signal controllers get real-time information
about the presence of vehicles from sensors in the roadway and on
poles. Controllers adjust the amount of green time for different
movements based on sensor information. The most sophisticated
controllers and software programs allow for the coordination of signals
along a roadway, so that vehicles can travel through a succession of
intersections without having to stop.
13.
14. DETECTORS
Detectors are used to identify the presence of a vehicle, so that the controller knows
how to adjust the amount of green time to provide. There are many types of
detectors. One type is known as the loop detector. The square black lines you may
see in the roadway as you approach an intersection are the visible part of the loop
detector, which is a thin wire buried in the roadway. When a vehicle drives over the
loop, it sends a message to the signal controller. The signal controller's software
evaluates the messages from all the loops at the intersection and changes the signal
timing appropriately. Small TV cameras can also be used to detect vehicles.
17. Types of Signal Operation
Traffic signals can operate on a pretimed basis or may be partially or
fully actuated by arriving vehicles sensed by detectors. In networks, or
on arterials, signals may be coordinated through computer control.
TYPE1
PRE-TIMED
TYPE2
SEMI-
ACTUATED
TYPE3
FULLY
ACTUATED
19. PRE TIMED OPERATION
A signal whose timing(cycle length,green time etc) is fixed over
specified time period and does not change in response to changes in
traffic flow at the intersection.
No vehicle detection is necessary at this mode of operation.
20. Pretimed Operation:
In pretimed operation, the cycle length, phase sequence, and timing of
each interval are constant. Each cycle of the signal follows the same
predetermined plan. “Multi-dial” controllers will allow different
pretimed settings to be established. An internal clock is used to activate
the appropriate timing. in such cases, it is typical to have at least an AM
peak, a PM peak, and an off-peak signal timing.
21. SEMI-ACTUATED OPERATION
A signal whose timing(cycle length ,green time etc) is affected when
vehicle are detected(by video,inductance loop detecters,embeded-
pavement etc) on some but not all approaches is called semi-
actuated signal.
This mode of operation is found where a low volume road intersect a
high volume road.
22. Semi-actuated Operation
In semi-actuated operation, detectors are placed on the minor approach(es)
to the intersection; there are no detectors on the major street. The light is
green for the major street at all times except when a “call” or actuation is
noted on one of the minor approaches. Then, subject to limitations such as a
minimum major-street green, the green is transferred to the minor street.
23. CONTINUE………
The green returns to the major street when the maximum minor
street green is reached or when the detector senses that there is no
further demand on the minor street. Semi-actuated operation is often
used where the primary reason for signalization is ‘‘interruption of
continuous traffic,”
24. Fully Actuated
• A signal whose timing(cycle length,green time etc) is completely
influenced by the traffic volumes,when detected,on all of the
approaches.
Fully actuated signals are most commonly used at intersections of
two major streets where substantial variation exist in all approach
traffic volumes over the course of a day.
25. Full Actuated Operation
In full actuated operation, every lane of every approach must be
monitored by a detector. Green time is allocated in accordance with
information from detectors and programmed “rules” established in the
controller for capturing and retaining the green. In full actuated
operation, the cycle length, sequence of phases, and green time split
may vary from cycle to cycle.
26. SPACING BETWEEN TRAFFIC SIGNALS

31. BEACONS
• Beacons are generally used to identify a hazard or call attention to a
critical control device, such as a speed and continuously in accordance
with the programmed signal –timing.
