ABSTRACT
Rumble strips, also known as sleeper lines or audible lines, is a road safety
feature that alerts inattentive drivers to potential danger by causing a tactile vibration
and audible rumbling, transmitted through the wheels into the car body. Transverse
rumble strips (TRS) are widely used by local authority in Malaysia to reduce vehicle
speed and alert drivers to any changes of the road. The objective of this study is; to
measure the differences between road with TRS installation and road without TRS
installation in terms of speed, and volume that contributed to the external noise
produced. The measurements were carried out through the noise level measurement,
vehicles speed measurement, and recording volume of vehicles that pass by through
the entire road.
The readings were recorded at a rural roadway that received
complaints from public which is at Pengkalan Raja, Pontian, Johor. Results showed
that TRS can increase the level of traffic noise, and annoyance response in
community. The analysis also indicated that residents at the respective location
receive strong impact that can lead to vigorous community reaction. The proposal
containing all of the findings hopefully would be beneficial to authorities in
improving the application practice of TRS.

ABSTRAK
Jalur jidar, yang juga dikenali sebagai garisan tidur atau garisan yang
menghasilkan bunyi, adalah satu ciri keselamatan jalan raya yang memberi amaran
kepada pemandu akan bahaya atau amaran yang akan dihadapi melalui getaran pada
tayar apabila tayar bersentuhan dengan permukaan jalan yang mempunyai jalur jidar
melintang. Jalur jidar melintang (TRS) adalah digunakan secara meluas oleh pihak
berkuasa tempatan di Malaysia untuk mengurangkan kelajuan kenderaan dan
menjadikan pemandu lebih peka kepada sebarang perubahan di jalan raya. Objektif
kajian ini adalah untuk mengukur perbezaan tahap bunyi di antara jalan raya yang
mempunyai jalur jidar melintang dan jalan tanpa pemasangan jalur jidar melintang
dalam jangka laju, dan jumlah kenderaan yang menyumbang kepada bunyi luaran
yang dihasilkan.
Pengukuran telah dijalankan melalui pengukuran tahap bunyi,
pengukuran kelajuan kenderaan, dan jumlah rakaman kenderaan melalui jalan
keseluruhan. Bacaan telah diambil pada jalan luar bandar yang menerima aduan
daripada orang ramai yang berada di Pengkalan Raja, Pontian, Johor. Hasil kajian
menunjukkan bahawa jalur jidar melintang boleh meningkatkan tahap gangguan
bunyi bising lalu lintas, dan tindak balas gangguan bunyi bising kepada penduduk
setempat. Analisis juga menunjukkan bahawa penduduk di kawasan yang menerima
impak yang sangat kuat yang boleh membawa kepada gangguan kesihatan.
Cadangan di dalam kajian itu diharap akan memberi manfaat kepada pihak berkuasa
dalam menambahbaikan penggunaan jalur jidar melintang.

INTRODUCTION
1.1
Introduction
Transverse rumble strips (TRS) may be used to call the road user’s attention
to standard regulatory and warning devices or to alert the road user of a changing
roadway environment where there is a need to exercise extraordinary caution. TRS
consist of raised bands of material or grooves cut in the pavement perpendicular to
the direction of vehicular travel.
These grooves provide a minimal amount of
vertical deflection of a vehicle’s wheel, resulting in the transmission of noise and
vibration in order to draw the road user’s attention to the feature of the road ahead.
Rumble Strips are an effective countermeasure for preventing roadway departure
crashes. The noise and vibration produced by rumble strips alert drivers when they
leave the travelled way. Rumble stripes is the term used for rumble strips painted
with a retroreflective coating to increase the visibility of the pavement edge at night
and during inclement weather conditions. In favourable circumstances, rumble strips
are effective (and cost-effective) at reducing accidents due to inattention.
On
freeways and motorways, the effectiveness of shoulder rumble strips is largely
dependent on a wide stable shoulder for a recovery. On two-lane roads, the effect of
shoulder width is not as pronounced.

1.2
Statement Of Problem
According to an article in a newspaper on 1st July 2002, Malaysia hopes to
reduce the fatal road accident rate to two deaths per 10,000 registered vehicles by
2020 from the present 5.17. The main cause of roadway departure crashes is driver
drowsiness and inattention, which are sometimes compounded by driving too fast.
Alcohol and drugs can contribute to both fatigue and speed. Driver fatigue also is
induced by highway hypnosis, which occurs when the lines and stripes on long,
monotonous stretches of highway reduce the driver’s concentration. When drivers
stray from the travel lane, rumble strips rouse their attention to allow a safe recovery.
Rumble strips are also helpful in alerting drivers to the lane limits where conditions
such as rain, fog, snow or dust may reduce the driver’s visibility. In attempt to
reduce speed on roadway segment where speed and accident is considered to be a
safety concern, various low cost countermeasures have been investigated. Such
countermeasures include Transverse Rumble Strip that gives psychological
appearance of narrowing and/or increasing speed have been considered as a
relatively low-cost treatment. But there are some report based on the problem arise
from this installation such noise disturbance to the surrounding area.
Noise is some of a big problem nowadays. If we refer to the World Health
Organization (WHO), noise can affect directly to human health such as high pressure
and emotional distress (Schomer, 2001).
Noisecan cause long-term effects of
chronic sleep disorders, communication disorders, emotional stressthat would affect
the quality of life of normal man (Schomer, 2001). In fact, there are studies that
found that noise contributes to cardiovascular problems and heart disease because of
stress and deck high emotional disorders (Sorensen et al., 2011).
When this problem occurs, public awareness is needed so that proper
consideration could be obtained in the determination of action to prevent it. To
ensure the comfort ability of the community life, all these values should be analyzed
and studied, both the positive and negative, and appropriate action should be taken so
3
that its effects balanced to be applied. Margin of the best bands are able to carry out
its functions as an important element of road safety, in addition to not increase the
level of noise that can interfere with the local community. Therefore, this study is to
examine the effectiveness of cross border strip in reducing vehicle speed, in addition
to studying the production of external noise produced and the impact on the speed of
sound production. Hopefully, this research can be consulted on the future, as well as
raise awareness of society about the application of horizontal margin of Goliath on
the road.
Kg. Pengkalan Raja, Pontian is a village housing area. There are about two
long set of TRS at the place. Distance from a house to TRS is about s ten meters.
Earlier observation and random interviews found that the local people are annoyed
with the noise of TRS.
Local representative has lodged a report to authority.
However, no further action has been taken. Therefore, evaluations are required in
order to determine the effectiveness of TRS installation and noise effect that interfere
with the surrounding.
1.3
Research Objective
Although there have been some limited evaluations of rumble strips in
previous studies, no significant field evaluation were performed. The objectives of
this study are to:
1.
To know the relationship between noise level, speed and traffic volume to the
pattern of noise produce from TRS
2.
To determine whether the level of noise that produce by TRS will annoy
nearby residents.
4
1.4
Scope of Study
The scope of study is about the noise level that produce by tranverse rumble
strip to the surrounding area especially in residential area:
1.
This study will be focusing about Tranverse Rumble Strip and their type such
as raised rumble strip that the most popular in Malaysia.
2.
Since MPJBT get some complain from two area in Pontian, Johor about the
noise that produced by tranverse rumble strip, the research will be conduct in
that area.
3.
Noise study will focus on transverse rumble strip in Malaysia, the type of
thermoplastic woke up and used as material in stallation.
4.
Sound level measurement carried out for an hour with an interva lof five
minutes.
5.
Parameters used for analysis in units of decibels 15hrs Laeq dB (A).
6.
This study was conducted in accordance with guide lines from the
Department of Environment, Malaysia, and the Planning Guidelines for
Environmental Noise Level, 2004.
1.5
Importance of the Study
The study of this research is about the factors of noises produced by tranverse
rumble strip.
The noise level will be defined at the final part of this study.
Hopefully the authority of the target area would take and utilize some information
5
from this study and take action how to solve the noise pollution produced by
tranverse rumble strip and at the same time can improve the traffic safety that can
satisfy the people on that area.
The study will produce effective design guidance margin strip across.
Effective rumble strip is capable of carrying out its functions of road safety such as
warning the driver, without interfering with the community and environment by
noise. The results of this study can also be used as a reference on the optimum
distance of residential communities and the road.
