INTRODUCTION
1.1 BACKGROUND
According to Malaysian Road Safety Department,3.9% road death increases in 2008
compared to the previous year. Traffic signs represent one of the most common
devices for controlling traffic in that they help regulate, warn, and guide road users. In
spite of their importance, traffic signs are not always clear to the drivers (Tamar &
David 2006).
1.2 METHODOLOGY JUSTIFICATION
i. To increase awareness and driving etiquette on road.
ii. To decrease road accidents risk.
iii. To improve the knowledge regarding road signs among students.
iv. To know the comprehension regarding road signs among students.

CHAPTER 2
LITERATURE REVIEW
2.1 DEFINITION
Definition of sign is an indication, an event, an action and a fact that shows that
something exists or may happen that you can find and see. Meanwhile, the definition
of road is a hard surface built for vehicles (Oxford Advanced Learner’s Dictionary 6th
Edition).
The general definition of road signs is a sign near a road giving information or
instruction to driver.
Then, the specific definitions of road signs are used to give information about the
location of either the driver or possible destinations and are considered a subset of
informative sign group (Ross & Alan, 1992).
2.2 TYPES OF ROAD SIGN
Types of road signs are divided into three parts which is first, law road signs such as
no entry, speed zone and stop. Secondly, warning road signs such as dangerous bend
road, slippery road and accident spot. Lastly, direction road signs such as destination
sign board and information sign board (Law T.H, 2004). Every each of these types
should be distinct in its shape and colors (Tama and David, 2006).
2.3 FUNCTIONS OF ROAD SIGN
Functions of road signs are use to arrange traffic, to warn and act as guidance to road
users. Besides, the designs of the road signs which are big, simple and similar are
5
easier for understanding, plus noticeable. This it can give enough time for road user to
be ready for a certain unexpected condition such as sudden animal crossing. The roan
signs are place in plain sight. Furthermore, the road signs are informative in terms of
providing directions. (Marc Green & John Senders, 2004)

RESEARCH METHODOLOGY
3.1 BACKGROUND
In order to do this research, we will survey the 1st year students of Faculty of Allied
Health Sciences (FSKB), National University of Malaysia, Kuala Lumpur (UKMKL)
intake 2008/2009. The selected students come from 12 different courses which are
Biomedical Science Department, Audiology and Speech Science Department, Dietetic
and Nutrition Department, Optometry Department, Diagnostic and Radiotherapy
Program, Occupational Therapy Program, Physiotherapy Program, Environmental
Health Program, Forensics Science Program and also Emergency Medicine Program.
From all the 383 students of the 1st year in FSKB, only 192 are selected to be our
respondents. Apart from that, we will later pick later based on the ratio of male to
female from the answered questionnaires. We then will get the population of student
either having or not having license. The license can be either `L` or` P` or even full
license also known as Competent License that are registered under Malaysian Road
Transport Department (JPJ).
3.2 RESEARCH DESIGN
We have selected the best way of designing our research. The cross-sectional study
will be the best and suitable research design for us. Basically, we don`t refer to any
other sources to get the result but we have to do the result based on our questionnaire
to the respondent. Moreover, the result can be analyzed easily using the SPSS system.
We also use open survey type question to gather all the respondent data.

3.3 SAMPLING METHOD
3.3.1. Target Population = Students of UKM, Kuala Lumpur.
3.3.2. Sample Population = 1st year students of FSKB intake 2008/2009 in UKMKL.
3.3.3. Sample Size = 192 students.(calculation from sample size of selected
population formula below)
Calculating sample size
n = ____X 2NP (1-P)____
∆2(N-1) + X2P(1-P)
= 192
Where X2 = 3.84, ∆ = 0.05, P = 0.5
But 10% would drop out so,

Section B(a)1 vs Section B(b)1
11
There are 64.4% students who answer correctly and really understand about this road
sign and only 7.9% did not know about this road sign but still can answer correctly.
There are only 16.7% said really understand but still answer incorrectly and 22.2%
students who answer incorrectly and did not know about this road sign although this
road sign quite common in used representing hospital.
12
Section B(a)2 vs Section B(b)2
There are 32.6% students who answer correctly and really understand about this road
sign and only 2.2% did not know about this road sign but still can answer
correctly.However,44.3% who said really understand but answer incorrectly and only
3.8% students who answer incorrectly and do not understand about this road sign. It is
because There are misunderstands this road sign with bumper sign.
Section B(a)3 vs Section B(b)3
13
There are 68.8% students who answer correctly and really understand about this road
sign and only 8.6% did not know about this road sign but still can answer correctly.
There are 37.5% who really understand but did answer incorrectly and 37.5% students
who answer incorrectly and understand about this road sign.
Section B(a)4 vs Section B(b)4
14
There are 73.9% students who answer correctly and really understand about this road
sign and only 8.9% did not know about this road sign but still can answer correctly.
But there are 60% who really understand but did answer incorrectly and 6.7% students
who answer incorrectly and not understand about this road sign. Supposedly, student
should know about this road sign because this road sign familiar for us and we can see
this road sign in every parking lot.
15
Section B(a)5 vs Section B(b)5
There are 73.2% students who answer correctly and really understand about this road
sign and only 7.4% did not know about this road sign but still can answer correctly.
Unfortunately,80% of students said really understand but still answer incorrectly and
about 20% students who answer incorrectly but understand about this road sign.There
is no students answer incorrectly and don’t know about this road sign.
16
Section B(a)6 vs Section B(b)6
There are 56.9% students who answer correctly and really understand about this road
sign and only 6.4% did not know about this road sign but also answer correctly. On
the other hand,a large percentage,that is around 57.1% who said really understand but
answer incorrectly and about 14.3% students who answer incorrectly but a bit
understand about this road sign.

There are only 28.1% students who answer correctly also really understand,39.3%
said understand about this road sign and 4.5% did not know about this road sign but
still can answer correctly. However, 34.9% students who said really understand and
32.1% said understand but answer incorrectly and only about 3.8% students who
answer incorrectly and did not know about this road sign. Maybe, students confuse
between this road sign with do not parking road sign.
20
Section B(a)10 vs Section B(b)10
There are 55.2% students who answer correctly and really understand about this road
sign and only 4% did not know about this road sign but still can answer correctly.
There are 38.1% students who really understand but also answer incorrectly and about
14.3% students who answer incorrectly and did not know about this road sign. It is
because there misunderstands with the narrow bridge sign.
21
Knowledge’s score and comprehension’s score about road signs are depend on types
of road signs and evaluation of students about that road sign. So, there are differences
between knowledge’s score and comprehension’s score regarding the road sign among
the first year FSKB’s students.
Objective 2: To determine the differences in knowledge between gender about the
road signs.
Hypothesis: There are differences in score of knowledge on road signs between
gender. The score are taken through the answer of question part A – no 1, part Ba &
C.
• HA, μ1≠μ2: There are differences in score of knowledge on road signs between
gender.

Through the calculation of skewness, the standard deviation (0.354) multiply by 2 and
the answer (0.708) is in the range of statistic value (-2.117 to +2.117). It shows that,
the distribution of the data is normal for the male. For the female, standard deviation
(0.198) multiply by 2 and the answer (0.396) is also in the range of statistic value (-
2.618 to +2.618). It shows that, the distribution of the data is absolutely normal. It is a
parametric analysis.
To compare the mean score of the two groups which are male and female student,
independent sample t-test is use. Score as the test variable and gender as the grouping
variable.

Mean score of knowledge and standard deviation for male is 13.8667 and 2.24216
while for female is 14.3533 and 2.26481.
On the output result, Levene’s test is higher than 0.05. It is assume that the data
variances are relatively equal. Therefore, the upper row of the significant value is use.
Base on it, the significance level of p value on the upper row is higher than 0.05.
Thus, the mean score of knowledge of the two groups are not significantly different.
t=1.267, df=193, p>0.05.

Through the calculation of skewness, the standard deviation (0.209) multiply by 2 and
the answer (0.418) is in the range of statistic value (-1.968 to +1.968). It shows that,
the distribution of the data is normal for student with license. For student without
license, standard deviation (0.306) multiply by 2 and the answer (0.612) is also in the
range of statistic value (-2.060 to +2.060). It shows that, the distribution of the data is
absolutely normal. It is a parametric analysis.
To compare the mean score of the two groups which are student with license and
student without license, independent sample t-test is use. Score as the test variable and
gender as the grouping variable.

Mean score of knowledge and standard deviation for student with license is 14.5746
and 13.5082 while for student without license is 1.72717 and 3.02557.
On the output result, Levene’s test is lower than 0.05. It is assume that the data
variances are relatively different. Therefore, the lower row of the significant value is
use. Base on it, the significance level of p value on the lower row is lower than 0.05.
Thus, the means score of the knowledge on road sign between student with and
without driving license are different.

Through the calculation of skewness, the standard deviation (0.219) multiply by 2 and
the answer (0.438) is in the range of statistic value (-3.095 to +3.095). It shows that,
the distribution of the data is normal for student live in urban. For student live in rural,
standard deviation (0.281) multiply by 2 and the answer (0.562) is also in the range of
statistic value (-1.498 to +1.498). It shows that, the distribution of the data is
absolutely normal. It is a parametric analysis.
To compare the mean score of the two groups which are student who living in urban
area and student who living in rural area, independent sample t-test is use. Score as the
test variable and area as the grouping variable.

For the data on interaction on mean score of knowledge to the gender, residential area
and availability of license to each student. From the table, there is negative value for
data in column B. the negative value shows the opposite interaction of the second
factor from the first factor to the score of knowledge
Here, interpreted that the mean score of knowledge for the second factor (female
student) is higher (due to positive value of B) 1.931 times (Exp(B) value) from the
first value (male student). Also, the data for this factor showing a non-significant
value, p=0.461

For area or residential, it shows that the mean score of knowledge of the second factor
(rural area) is lower (due negative value of B) 0.916 times compared to student from
urban area. The data of significant also shows there is no significant value for this
factor, p=0.908
License showing the score of knowledge for the second factor (not having license) to
be low than the first factor (having license) by 0.124 times less. But, the significant
value show that there is a significant data to be observed, p=0.018
There are different in the score of knowledge on license but there is no different in the
score of knowledge between genders and resident.

CHAPTER 5
DISCUSSION
5.1 DISCUSSION
A recent study that evaluated comprehension of traffic sign in four different countries
show that comprehension level varies widely and is apparently related to the extend
that the sign’s design incorporate ergonomic guidelines for good design(Shinar D. et
al 2003). Based on our research, we found that comprehension and knowledge of
students about the road sign is depend on types of the road sign. There are road signs
that show high scores of comprehension and knowledge about the road sign but there
are also road signs that show high score of comprehension but low in score of
knowledge about the road sign and etc. What we can get from this situation is sign
design should be guided by established ergonomics principles to enhance
comprehension, especially for drivers who have not had prior encounters with specific
signs (Tamar B. & Shinar D. 2006).
From the Chi-square test, it shows that the driving school is the main source
in contribute to student knowledge in the road sign compared to mass media,
campaign, environment and others. This is because, from the Kementerian
Penerangan Malaysia, to get the license from driving school each individual need to
pass road law test and usually the test is done by on-line. In this test, every
participant must achieve the standard marks that standardized by Jabatan
Pengangkuatan Jalan, Malaysia. After that, they will expose and apply their
knowledge about the road sign during lesion and test of license. So, the experiences
in the driving school help them to increase their knowledge about the road sign. In
other words, the most factor that influence the score of knowledge is license
compared to other factors that is gender and residential of students.
35
The knowledge about the road signs is very important because from Dr. Haji Mat
Saad Abdul Rahman, Fellow Kanan Syariah Pusat Syariah, Undang-undang dan
Sains Politik, Institute of Islamic Understanding Malaysia (IKIM), presence of road
sign in certain location especially in danger zone is one of important matter to
decrease the fatality rate in road accident.
36
CHAPTER 6
CONCLUSION
6.1 CONCLUSION
License is the most factors that influence the student’s knowledge compared to
gender and residential area. Female students obtain higher knowledge more than
male. Students that live in rural area obtain lower knowledge than urban area.
Student without license obtain lower knowledge less than students with license.
6.2 SUGGESTION
To get the more accurate data, interview is the best way to evaluate student’s
knowledge about road sign to reduce the bias. While developing questionnaire, more
road signs should be added in questionnaire so that our result fulfill the objective in
this research. Furthermore, this questionnaire also can help students to improve their
knowledge about the road sign.
