Abstract— Policing of road traffic in Sri Lanka has become a major task for the police as a consequence of the traffic accidents and
congestion that increase immensely
...

Traffic rules violations cause disturbance to numerous parties and consumes time
...
With the increase of the number of vehicles on the highways causing continuous
traffic congestions in the cities especially during the peak hours, it is difficult for the police to focus on individual vehicle
...
The project, “Traffic Rules Violation
Detection System” aims to monitor, detect and to control the violation of traffic rules which overcomes the above mentioned
constraints in Sri Lanka
...
The challenge the team will has to face is image
processing in changing climates
...


Keywords: Traffic, violation, detection, image processing, congestion, SMS, TRVDS

...
To resolve traffic jamming and to
make good use of roads, solutions are often pursued
through traffic signal control systems and traffic
information services
...
There are two basic
types of traffic surveillance systems: road-based
and vehicle-based
...
Similarly, there are
numerous ways have been implementing to observe
the traffic congestions
...
It is
crucially required to build security in the
community with minimal intrusion into the privacy
of the public after the humanitarian operations
emerged as a priority requirement of the society
...
This leads to issues such as where
police may not be able to track all the vehicles that
violate the traffic rules and when they caught a
vehicle the police has to take the driving license of
the driver and charge a penalty from the driver for
the violation of traffic rules
...
So the research
team has tackled these problems and provided an
automated way of detecting the traffic rules
violations to overcome this issue

Even if the video camera based
technology is involved in some areas, the detection
of traffic rules violations during the peak hours is
difficult
...
Consequently,
assurance about the safety on the road is not
confirmed
...
Each station in a division maintains a
traffic branch and the officers with the traffic duties
have to examine the vehicles investigate traffic
accidents and court procedures
...
Therefore there is a possibility for the
police to track the vehicles that violate the traffic
rules and it is hard for policemen’s to stand all day
near a junction and look for the vehicles that violate
the traffic rules
...

II
...

Below mention existing systems has several
different advantages compare with the manual
traffic violation detection systems
...

Quite a number of similar and related researches
were found after studying some other research work
and major activities done on number plate

identification systems
...
OpenCV class libraries can be used to
achieve the processes mentioned above
...
Following shows researches done with
regards to the components of the “TVDS” System
...
To identify the
characters, only the dark-and-light sequence is used
...
If more than one candidate
characters are identified, then by using any of the
seven other processing techniques, the number of
surviving candidate characters can be reduced to a
single character
...
The Zigbee transmitter sends the
speed limit of the particular lane entered by the
vehicle and also gives alerts like “road works”,
“steep slopes”, “school zone” in the form of
acoustical messages and also in LCD
...
When speed of the
vehicle nears the speed limit it displays the warning

and if exceeds the limit, the microcontroller records
the violated speed and time
...
A GSM module sends message
to the nearest traffic personnel immediately after a
violation occurs
...
Increase in the count of violation
increases the penalty amount which can be
collected in toll gates located nearby
...
[4]
In a research done by VTT Technical Research
Center, which contain within a small trailer, which
can be towed and set up at any roadside location
...
It can also monitor road surface
conditions, and calculate traffic emissions
...


It is a system for monitoring and reporting
incidences of traffic violations at a traffic location
is disclosed
...
The camera
system is remotely coupled to a data processing
system
...
[3]

Research Gap

Significant number of literature reviews had been
reviewed by the research team of TRVDS in order
to find out the gap which has not been covered
...
In Sri Lanka, the traffic
violation control system is a manual system
...
Therefore the TRVDS
system ensure the safety on the road and time
saving by detecting the violations done by the
drivers and pedestrians
...
And then a SMS will be sent to the
owner of the vehicle with the relevant information
...
Further it defines digital image
• SMS system to send the information about the
processing as an area illustrated by the requirement violation and the fine to the vehicle owner
...
Therefore the TRVDS system will be an
efficient way to detect the violations and to control
the traffic congestions
...

...
They are
number plate identification, character identification,
penalty calculation and messaging system
...
This
is an image processing based system so each of
these modules should go through testing phase to
reduce the number of errors and improve the
efficiency
...
C++ is used as the
main programming language while OpenCV and
Tesseract OCR class libraries are used for image
processing part and also php is used to design the
website of the system
...
The specialty of this methodology is
development team and clients can check the current
status of the developing system without staying till
final product is released

Planning

In the planning phase research team had meetings
and discussions with team members about how the
development should be carried on and how the
development parts going to develop
...
To develop the system “TRVDS”,
Prototype software methodology is used because

Analysing process of all existing systems and
past researches was carried out in this stage
...
Most importantly, the
research gap of the project was clearly identified in
this process
...

Problem Analysis –
In this stage the current individual systems were
analyzed, how they operate, their strengths and
weaknesses, how can they be integrated and came
with a solution that is proposed system – TRVDS
Information Gathering –
The data was gathered in two aspects
...

• Primary Data:
Several interviews were conducted with
Department of Traffic Police and the vehicle
owners
...

• Secondary Data:
Through the internet, research team searched past
similar projects done related to the expressways and
toll collecting methods and at the same time
...


Design

The primary objective of the design phase is to
create a design that satisfies the agreed application
requirements
...

Physical design – In the physical design, the
logical diagrams that show the analysis phase
requirements are converted to physical diagrams
...
The
input, output, storage, processing, recovery and
backup requirements are identified
...
This
system will be client-server architecture, therefore
would build the processing for the system into the
server
...

A network model then needs to be developed to
Figure 1: Architectural diagram
show how the computers, mobile phones, remote
devices will be located and connected to each other
...
The team will be more
the figure below:
concerned on the website which is designed for the
users to login to pay their fine
...
The colors of interfaces will be
attractive and sensible to use
...
The Arduino, GSM module, client
side applications and server side applications will
be separately programmed and merged together
...

...
Here performed in order to make sure the system is
the research team transformed the design output to complete, meets the need that is to increase
actual modules that will work completely
...

implementation reflects the design decisions
...

RESULUTS AND DISUSSION
Construction – Actual construction and
This section will discussed about the findings of the research
programming took place in this phase based on the and how it works and compared the research with similar
modules produced in the previous phases

was built
...

receiver is placed on the either sides of the pedestrians
Installation – As expected the server side
applications will be installed, the developed
hardware components will be fixed to the cart and
programmed
...
Navigation application will be
integrated with radio frequency mediums for
processing
...
With the
developments of project success the team might
implement up to the commercial level
...


Testing

Testing was done in all the components in the
design phase iteratively and in the final stage also
after implementing the final product a software test
was done again to finalize the product
...

A test plan was developed which defines the series
of tests that was conducted
...

Integration tests were carried out to assess whether
the set of modules or programs that must work
together, do so without error
...
Acceptance test were

crossings near the traffic lights and the camera is fixed on the
traffic lights
...


Figure 2: How the transmitter and Receiver should be placed
As soon as an obstacle comes in between the transmitter
and a receiver, the receiver would not receive the signal
transmitted by the receiver
...
Arduino board will be used
as a microcontroller of this system because it gains some
higher throughput and the cost of the system can be reduced
...
Inside the
ISR (Interrupt service routine) a code will be written to what
have to be done when the receiver doesn’t receive the signal
transmitted by the receiver
...

The system assumes that the IR sensors are working only
when traffic lights are in Red mode, else IR sensors consume
more power for processing
...
Then the captured
image will be taken to extract the number plate
...

Number plate identification Process
In the development phase, research team found that using a
high quality image is more efficient than processing the live
video
...
To isolate the number plate from the whole image
several techniques are used
...

1) Filter the Colours
2) Highlight the lines and edges in the image
3) Find the shapes in the image
4) Filter rectangles using area
5) Crop the identified rectangle areas
Online Payment Module
The research system extend capabilities and user satisfaction
by including a web site to pay the fines
...
The people who violate
the traffic rules can login to the TRVDS system and pay the
fine online
...


A
...
As this is a number
plate identification system, the accuracy of the identification
method should be precise as far as possible
...
Except in situations
such as different light conditions and bad weather conditions,
all the other times the system can be considered as a well-built
program without any errors
...


Availability

The system will be available for the operator at police station
during 24 hours
...

Security
Security will be handled by the application itself
...
Only the administrator has the access to
the database and makes major changes to the internal structure
of the system
...

V
...
With the help of the advanced technology, a
way of reducing the number of traffic rules violations can be
offered to some extent
...
9
...

Project TRVDS will suggest better solutions to address the
problems occurred and to improve the efficiency and the
safety of the road
...
To use the TRVDS system there should be
special equipment’s such as a signal transmitter and receiver
at the traffic lights and as well as an Arduino board and a
camera
...
By using this proposed system SLP can ensure the
safety on the road and also at the same time the safety of the
drivers
...
TRVDS system is capable of
providing weekly and monthly usage reports to the SLP about
the violations for future references and also for the data
mining purposes
...

Efficient and Safety transportation plays a significant role
when considering major developments of a country and it is a
very important fact which every country ought to have gained
in order to obtain the fully developed status
...

Future work
• Increase efficiency of the feature extraction method
...

• Add more useful features to the main System that can help to
the Operators
