ABSTRACT
Roads in Malaysia are getting more congested every day and the problem does not
seem to have a solution. Many researches are done to reduce the traffic congestion
however there are no practical or real-time solution to the problem. Most researches
are only able to simulate the traffic or rather generalize the pattern into simpler arrival
models, however this will not reflect on the actual road conditions. In this research, an
alternative approach to measure the traffic intensity on the road is discussed. With
computer vision has become a key business element in many corporations and the rise
in the technology of cameras with lower costs of processing has enabled us to develop
on most advanced system for many applications. Using traffic surveillance camera
placed on roads and object detection algorithm, a new method of calculating the traffic
intensity is developed and tested. Results of the test show the accuracy of about 80%
for the algorithm to be able to tell the difference between number of cars and
motorcycles. With this information, the road condition is estimated with higher
accuracy. The result and performance are tabulated and some of the limitations are
discussed in detail in the last chapter. However, there is still a lot of work need to be
done until the application can run accurately in real-time.

CHAPTER ONE
1. INTRODUCTION
1.1 BACKGROUND OF STUDY
In the modern world, the rise in the number of cars, buses and other modes of
transportation has led to increase in frequency of traffic congestion across the world.
Uncontrolled urban development and improper planning in infrastructure has
exponentially increased this problem where everyone using the public road system
will face the same issue of bad traffic congestion(Abdelfatah, Shah, & Puan, 2015).
Vision based traffic monitoring system is a good solution to address this problem(T.
Chen & Lu, 2016; Datondji, Dupuis, Subirats, & Vasseur, 2016). Furthermore, object
detection and tracking of multiple objects are important research done actively in the
computer vision field to aid on this problem.
New tools are necessary to monitor the traffic conditions in high density areas.
There are many researches written in the past regarding this issue but recent
developments in high speed internet and number of traffic cameras in the streets by
governing agencies has increased the need for more advanced traffic detection and
tracking for vehicles more important. Currently, these processes are done using the
control tower which has people in them to monitor the traffic conditions among all the
cameras located on the highways but this is no longer practical when the number of
cameras increase with the rise of the number of highways. Therefore, more resources
will be needed to monitor them unless some tool to monitor them automatically are
developed.

However, there are still a lot of problems using traffic surveillance camera for
vehicle detection. Some of the most critical problems are occlusion of object in field
of view, glaring from bright light of car’s headlights and taillights, weather influences
on lighting and so on. Different researchers have done significant research to increase
the accuracy of result using traditional approach however these methods still take a lot
of time for image processing. The unpredictability of the drivers also tends to make
tracking more difficult than it should be.
Another great challenge of using traffic surveillance camera is the accuracy of
measuring the four main criteria of true positives, true negatives, false positives and
false negatives. In a heavily congested traffic condition, it becomes highly unreliable
to use such techniques to measure the traffic intensity but in this research, neural
networks may be the key of solving this problem.
Current technology on identifying the road traffic intensity depends on data
from the users of the roads(P.T. Chen, Chen, & Qian, 2014). Many researches are also
done using data mining approach to sort out relevant data from the user’s mobile
phones and social networks uploads to map out the road conditions in real time.
Applications such as Waze and Google maps uses GPS location data from its users to
map certain road conditions and also to predict future patterns using machine
learning(Graves et al., 2016). This method is a good platform for this application.
However, this approach relies heavily on the user data and network intensive for
typical usage.
A robust system that not only identifies the traffic intensity but the vehicle on it
is also necessary to create future databases of vehicles accessing the roads(Flores,
Mata, Fernandez, Aliane, & Puertas, 2014)(Yeh, Zhong, Member, & Yue,
2017)(Elleuch, Wali, & Alimi, 2015). By predicting the vehicle types and numbers, a
3
restriction policy can be enforced to reduce the congestion by limiting heavy vehicle
on certain time on the day and light vehicles on the other. Such practices are used in
some highways in Malaysia. The system should also be able to reroute traffic if the
roads are getting congested to reduce the overall congestion time. Incidents like traffic
accidents and road blocks are unexpected forms of danger that should also be
considered for this system to work efficiently.
1.2 BRIEF INTRODUCTION TO TRAFFIC MODELLING
Figure 1.1 Typical Highway in Malaysia (Source: http://www.thenutgraph.com/buy-
back-of-privatised-highway-concessions-more-cost-effective/)
Figure 1.1 shows a typical link on a road system in Malaysia. Most of the road system
employs a 2-way traffic flow in opposite directions. The input to the road is vehicles
and the output is also vehicle. Normally, there is no discrimination on the speed the
vehicles are supposed to be moving in the link. Traffic modelling technique involves
using Mathematical application to measure the parameters related to traffic.
These studies are extensively done by the London Traffic management for the
Mayor of London. (Blewitt & Smith, 2010) was part of the team that modelled the city
4
of London extensively with model including total travel time, congestion control
schemes, error handling approach as well as efforts to reduce carbon footprint.
However, the roads in all the cities across the world will have a different
approach to solve this problem as the traffic in these countries are treated uniquely.
Streets of Europe will have a different law compared to the ones in Asia such as the
speed limits, units of measurement metrics and so on. In chapter 2 of this thesis, the
modelling techniques from different perspectives will be discussed in detail however
the most basic problem to solve is counting the number of cars entering the link as
shown in figure 1.2.
Figure 1.2 The location of the tracking window
As vehicles move across the link, it will flow in single direction. The vehicles
on the right-hand side are monitored from window 1 to window 2 while the left-hand
side are tracked from window 2 to 1. When the vehicle is detected from the first
window, the object is initialized and counted while it moves along the road. A timer is
5
used to determine the time taken for the vehicle to reach last tracking window and the
number of vehicles are recorded.
The time measured between these windows and the number of vehicles are
variables used to determine the traffic intensity of the road. If the number of vehicle
on a certain time is high and the time taken for it to travel is long along with some
other parameters, then it can be concluded that the road is congested or not. Error may
occur in tracking all vehicles therefore a measure of accuracy is important in this
research.
1.3 STATEMENT OF PROBLEM
In recent years, the time spent by average people on the road has risen to an average of
spending about 32 hours per year on traffic congestion(Sabur, 2017) in europe while
Americans spent about 42 hours per year(Anderson, 2016). Stuck in traffic congestion
has become a routine in our daily lives but we cannot be living with this problem
anymore. With much advancement in autonomous driving and rapid development in
computer vision, the tools are readily available for us to solve this problem in the
future. However, there are some parameters in real time and space are not considered
in these solutions.
There is a real need for a completely autonomous system to handle traffic
congestions in Malaysia (Abdelfatah et al., 2015). Most algorithms developed by
plenty of researchers have not been able to detect traffic patterns in real world but
only track the movement of objects in general motion and predict their direction using
basic assumptions. A more realistic approach is needed to model these conditions
related to road management instead of treating it as a networking problem. Current
6
approach of using the Poisson Distribution used on the road traffic may be inaccurate
due to human action being indeterministic while driving on the road makes it harder
to predict the traffic flow based on predicted statistical data.
Furthermore, with the improvement in machine learning, the accuracy of data
can be significantly increased for training the detection of objects. Most algorithms
discussed in the next chapter focuses on using Haar Cascade for vehicle
detection(Hasan, Arif, Asif, & Raza, 2017)(Wu, Kang, & Zhuang, 2016). Though this
is a simpler process to handle, it takes a long time to train the cascade and the set of
images for training the module is always constant. However, using machine learning,
the accuracy can be improved by inputting the positive images back into training
sequence images. This approach is still lacking in many research currently as most
image processing is moving forward to hardware based acceleration using deep
learning.
Using multiple sensors are also an alternative way for vehicle monitoring.
However, these sensors are not able to provide enough information as accurate and
complete as using computer vision. Multiple researchers used this approach to map
traffic conditions such as wireless sensor network(Collotta, Pau, Salerno, & Scata,
2012)(Ito, Hirakawa, Sato, & Shibata, 2016) which incorporated sensors into cars to
monitor them but this will not only incur cost but add more privacy issue later when
implemented. Other research used RFIDs tagged in the cars and monitoring them with
high accuracy however, the infrastructure is not feasible for large scale application as
the data will be huge. This has shown a rise in need for traffic monitoring.
In current time, the status quo uses GPS data from the phones and social media
as well poses additional risk of privacy violation. Applications such as Waze, Here
maps and Google Maps are commonly used by people and network traffic is generated
7
by them to be sent to the servers. Multiple research and experiences in the past shown
that even the most secured systems are vulnerable to attackers and user information
are loss which justifies the need for alternative ways of acquiring data.
With most highways in Malaysia equipped with traffic cameras the solution
seems clear but currently vehicles are monitored using analog means such as control
rooms with people and traffic patrols. This is also a waste of resources such as
cameras not being used to their full potential and road repairs and assistance during an
emergency. With the rapid development in Computer Vision(CV) technology this
problem must be solved quickly.
Moreover, developing an automatic system that predict traffic flow may able
these governing bodies to develop new traffic models for implementing alternatives
options if there is a congestion or accident on the road without relying on the current
technology.
1.4 RESEARCH OBJECTIVES
The objective of this research as follows:
1. To develop a model that can analyse traffic pattern in real time.
2. To identify traffic intensity in a video sequence using MATLAB.
3. To evaluate the performance of the proposed system.
1.5 RESEARCH SCOPE
To simplify the research, and data collection, the following are the scopes of this
study:
1. A single camera monitoring the oncoming and ongoing traffic in 2 directions.
2. Only three scenarios are studied on the road for data collection namely the no
congestion and higher congestion.
8
3. The traffic camera will only record on the day and clear weather to remove
complexity to developing the program.

CHAPTER TWO
2. LITERATURE REVIEW
1.8 INTRODUCTION
In this chapter, the works related to the research area and the state of the current
research are discussed. The key limitations of current systems of multiple object
detection and tracking in Traffic Surveillance are identified. This chapter will also
provide an overview of the multiple road traffic modelling techniques currently being
used by authorities and researcher in real time. Some basic comparison of the
modelling schemes is presented and discussed further. Next, some basic object
detection systems assessed with some introduction into machine learning. Finally, the
chapter is concluded with a summary.
1.9 OBJECT DETECTION AND TRACKING TECHNIQUES
Research on visual tracking and computer vision are still developing as it has a wide
range of applications ranging from military to medical, security and surveillance.
However, image detection systems are only as accurate as their classifier because they
are only mapped on to objects from similar characteristics. However, this may not
apply to many objects from around the world. This issue has been actively researched
by many experts in different fields of study. There are different perceptions from
people from Civil Engineering background and Network Engineering background as
both are solving traffic flow in networked infrastructure.
