EARTHWORK DESIGN
1.1 INTRODUCTION
Earthwork define as the processes whereby the surface of the earth is excavated and transported
to and compacted at another location. In other words, earthwork is a construction process that
involves the alteration of the topography of a site to meet the design specifications. This process
involves removing or adding soil, rock, or other earth materials in order to achieve the desired
elevation, slope, or contour of the land.
The process of earthwork can be complex and involves various techniques, such as
cutting and filling, excavation, and grading. It also involves the proper management of earth
materials, including the removal and disposal of excess soil and rock. This process is often
time-consuming and labour-intensive, and requires heavy machinery and equipment. Despite
being a critical aspect of construction, earthwork can also be one of the most expensive steps
in the construction process. In fact, it is not uncommon for earthwork costs to account for more
than half of the total construction budget. This is due to the large amounts of earth materials
that need to be moved, the heavy machinery required to perform the work, and the skilled
labour required to operate the machinery and complete the earthwork.
The introduction of the internal combustion engine, electric power and hydraulic power
have led to the development of a wide range of earthwork plant such as its size, capacity and
efficiency. The scale of earthwork is range from small works where the excavation of ditches
and trenches for drainage and pits and trenches for foundations to the large earthwork such as
highways and dams. It carried out at an early stage in a construction project and completion of
the earthworks within the scheduled time is often the key to the completion on time of the
whole project. Normally, the success of earthworks process depends on:
i. An adequate site investigation and preparing practical and satisfactory designs of the
earthworks
ii. The choice and efficient use of the correct types and size of plant to meet the particular
requirements of the site.

BS 6031: BSI British Standard Code of Practice for Earthworks is code of practices and
standards which it gives recommendations on the design and construction of earthworks in
general civil engineering schemes.
This section will focus on explaining the aim and extent of the study that was conducted before
the engineering report was produced.
A site investigation was conducted to meet the requirements set by the local authorities
and follow the British Standard Code of Practice for Site Investigation (BS 5930: 1981). This
study was done to gather information about the soil at the construction site and produce a soil
profile report. The report includes information from field investigations, laboratory tests, and
recommendations from engineers on topics such as pollution control, slope stability, soil
erosion protection, and measures to improve the soil's strength and condition. The purpose of
the site investigation was to make sure that the soil at the construction site is safe and suitable
for building. The investigation produced a report with important information about the soil and
suggestions for how to make it better for construction.

ii. Standard Penetration Test
The laboratory tests for the on-site that were conducted are as follows:
i. Particle size analysis: This test determines the distribution of soil particle
sizes, which can be used to classify the soil type and
predict its engineering properties.
ii. Atterberg limits: These tests determine the consistency of soil and its
behaviour in wet and dry conditions. The tests include
the liquid limit, plastic limit, and shrinkage limit.
iii. Proctor compaction test: This test measures the maximum dry density and
optimum moisture content of soil, which can be used to
design earthworks.
iv. Unconfined compression test: This test measures the strength of soil in an undisturbed
state and is used to determine the bearing capacity of
the soil.
v. Consolidation test: This test measures the compression and settlement of

The design technique used during the site construction will play an important role in ensuring
the safety and efficiency of the earthwork process. The aim is to ensure that the earthwork
process is both safe and cost-effective, by utilizing an appropriate design technique. The
following is a detailed explanation of earthwork design:
i. Site Characterization
The first step in earthwork design is to gather information about the site, including its
geology, soil type, topography, and any other relevant information. The information is
used to determine the suitability of the site for the proposed project and to plan the
earthwork process.
ii. Environmental and Economic Considerations
- The design and construction and the cost of earthworks are generally dependant on
the environment in and around the site, the ground conditions within the site, and
the availability of materials for earthworks in the area.
- The landscape of the area should be taken into consideration which the earthwork
should not disfigure but blend into the environment such as the suitable profiles of
earthwork, amenity embankments and tree planting.
- Balance the amount of fill arising from cutting with the amount of fill required to
construct the embankments which can reduce the cost of earthworks. The reduce
6
the cost of earthworks can be carried out by minimise the quantities of imported
materials and minimise the material to be disposed of off-site
- Consider natural and waste resources in the area, such as are produced from the
local mines, pits, quarries, and power stations as fill required to construct the
embankments
iii. Excavation Design
This involves the calculation of the volume of earth to be removed from the site and the
design of the excavation process. Factors such as access, slope stability, and the location
of existing structures are taken into consideration to ensure a safe and efficient
excavation process.
iv. Grading Design
Grading refers to the process of shaping the land to the desired contours and elevations
for the construction of buildings, roads, and other structures. The design of grading
takes into consideration factors such as slope stability, drainage, and erosion control.
v. Drainage Design
Proper drainage is essential to ensure that the site remains stable and that water does
not interfere with the construction process. The drainage design considers the site's
topography, soil type, and the location of existing structures to determine the best
approach to manage surface and subsurface water.
Site clearing is a key step in the construction of infrastructure projects since it requires the
removal of existing vegetation, structures, and other materials from the site to make space for
the new development. The following is a detailed explanation of site clearing:
i. Site Survey
The first phase in clearing a site is to conduct a thorough survey to identify all existing
structures, vegetation, and other materials that need to be removed. This information
can be utilized to plan the site clearing process as well as estimate the cost and resources
needed.
ii. Vegetation Removal
This includes clearing the site of trees, shrubs, and other vegetation. Hand tools or
heavy equipment, such as bulldozers can be used. The methods used will be influenced
by the number and type of vegetation as well as the site's location.
7
Before beginning the site clearing activities, the contractor will identify any existing drains on
the site and their flow path until they reach the discharge point. A silt trap will be put in place
to capture any sediment before it can reach the existing drain. A temporary earth drain will be
constructed to manage surface water during the clearing process, and regular desilting will be
performed to ensure the drain remains effective. The existing drain will also be maintained
during this time. To minimize disruption to the slope area, the existing vegetation, such as grass
or small trees, will be cut rather than removed. In case it's necessary, plastic sheets or canvas
will be available on the site to be used for slope protection.
For construction sites with at least 5 acres (20,000 m2) of available space, sediment
basins are often utilized instead of silt traps. The design criteria for these measures are based
on the Planning and Design Procedure No. 1 and the Standard and Procedures for Peninsular
Malaysia from the Department of Irrigation and Drainage Malaysia (Manual Saliran Mesra
Alam Malaysia). The design concept for the temporary drain and silt trap is as follows:
8
i. A temporary earth drain around the perimeter of the work site to redirect silt water
away from the construction site and into the silt trap, preventing it from flowing
directly into a nearby marsh or river.
ii. Silt traps must be built and maintained in such a way that they capture silt from
dirty water before it enters the drain.
iii. All filtered water (via silt trap) from this development will be discharged into the
existing drain.
After the site has been surveyed and any required demolition has taken place, the landscape
will be cleared and grubbed. Clearing involves removing all vegetation, while grubbing refers
to removing the roots that remain in the soil after clearing. This includes removing logs, brush,
and debris, and grinding or removing stumps with machinery such as a bulldozer, dump trucks,
compactors, and scrapers. After these land-clearing steps have been completed, the site will be
ready for the installation of drains and grading work.
Stripping topsoil refers to the process of removing the top layer of soil, typically the fertile
layer, in preparation for construction work. This is typically done when building roads,
pipelines, bridges, and other types of infrastructure. The topsoil is removed so that the
subgrade, the layer of soil directly below the topsoil, can be properly compacted and levelled
to provide a stable foundation for the infrastructure. The stripped topsoil is often stockpiled
and used later for landscaping or other purposes. The stripping of topsoil is a necessary step in
the construction of many types of infrastructure, but it can have significant environmental
impacts, such as soil erosion, sedimentation, and loss of topsoil fertility. For these reasons, it
is important to carefully manage the stripping of topsoil and minimize its environmental
impact.
Before starting the process of stripping topsoil, all measures aimed at controlling
erosion and sediment must be fully implemented and working correctly. If the contractor
wishes to use a stockpile location that has not been indicated on the plans, they must seek
written approval from the superintendent at least three working days before beginning to
9
stockpile materials. The proposals for such use must detail the anticipated maximum size of
the stockpile, which must not be taller than 2.5 meters.
Cutting and filling involve the movement of soil from one place to another to achieve a level
ground surface. This process involves digging out soil, resulting in a "cut," and then using that
soil to fill another area, creating a "fill." The goal of cutting and filling is to create a uniform
ground surface by redistributing the earth. Cutting and filling land can pose a risk, particularly
when the filled land is intended to serve as the foundation for infrastructure projects. The act
of moving soil disrupts its natural compaction and can result in a "fluffed" or "aerated" state.
To make the soil safe for use in foundations, it is necessary to compact it to prevent settling.
Improper compaction of the filled soil can lead to serious consequences, such as cracked
foundations. The following are the advantage of cut and fill:
i. Cost-effective
Cut and fill is often a cost-effective way to modify the topography of a site, as it
allows the construction team to use the soil that is removed from one area of the site
to fill in another area, reducing the need for additional fill material to be transported
to the site.
ii. Minimal waste
Because the soil that is removed during the cutting process can be used as fill
material, the cut and fill method generates minimal waste compared to other
methods of modifying the topography.
iii. Versatility
Cut and fill can be used to create a foundation for a variety of structures, including
roads, buildings, bridges, and retaining walls.
In conclusion, cut and fill is a common and versatile method for modifying the
topography of a site, but it requires careful planning and execution to ensure that the final result
is safe and stable.
In construction, it is important to prioritize safety and health to prevent any accidents from
occurring. To ensure the safety of workers involved in earthwork activities such as clearing,
excavation, and cutting and filling, it is important to provide them with the necessary protective
equipment, such as helmets, gloves, and safety glasses as required. This helps to protect
workers from potential hazards during the operation.
1.14 RESULT OF EARTHWORK
The design for the project is based on guidelines set by the Department of Irrigation and
Drainage Malaysia's Planning and Design Procedure No 1 and its accompanying Standard and
Procedures for Peninsular Malaysia, as documented in the Manual Saliran Mesra Alam
Malaysia (2000) volumes 1-20. Additionally, the calculation of drainage measurement is
performed in accordance with specifications from the Jabatan Kerja Raya (JKR).
The cut and fill activity is summarized in Table 2, which provides a condensed overview of its
outcomes.

DRAINAGE DESIGN
2.0 Introduction
Drainage is the process of removing excess water from a flood-prone area, whether that be
done naturally or artificially. Many soils need artificial drainage to increase output or better
manage water supply, despite the fact that most agricultural soils had sufficient internal
drainage to prevent severe waterlogging (anaerobic conditions that damage root development).
The drainage system helps the ballast bed function correctly by collecting and diverting ground
and/or surface water. Open ditches, closed ditches with pipe drains, and stormwater drainage
pipelines, channels, and culverts are all part of a comprehensive drainage system that ensures
the substructure is properly drained.
The drainage design calculation is based on the Rational Method, which is often used in
Malaysia to estimate the runoff peak. The method good practices for drainage catchments with
an area of less than 200 acres.
• The peak flow occurs when the entire catchment is contributing to the flow;
• The rainfall intensity is the uniform over the entire catchment area; and
• The rainfall intensity is uniform over a time duration equal to the time of concentration,
tc.
i. The actual flow of the rational method is calculated using the equation.

SEWERAGE DESIGN
Sewage treatment is the process of removing pollutants from wastewater, often from
household sewers. It is crucial to choose the right location for the sewage treatment facility.
To have a functional sewage system, sewers must be properly planned. Sewers are meant to
drain wastewater from homes, businesses, roadways, and streams in order to preserve the
environment and people from serious diseases, as sewage spreads more than 50 diseases. In
this project, we will just assess how the sewerage piping is laid out and the ideal site for a
sewerage treatment plant, such as the height at which it should be constructed.
2. Three (3) sets of drawings shall be submitted. The Authority shall return
two (2) sets of the approved drawings to the Consultant.
3. One (1) compact disc (CD) containing the approved Sewer Plan in PDF
Format shall be submitted to the Authority.
Design shall be in accordance with the requirements of the latest Sarawak Urban Sewerage
Systems Guidelines.
N DESIGN
O. CRITERIA
ii. The trench must be dug out wide enough to allow for at
least 300mm of working space on either side of the pipe
when it is properly positioned. At every joint, a trench
must be dug out with a minimum working area of
300mm all the way around the joint.
iii. Excavation of the trench shall not take place more than
100m in advance of the finished pipeline with its
backfill. At the conclusion of each workday, pipe must
be put in every trench that has been dug, unless the
Contractor receives permission from the S.O. to do it
differently.
iv. All existing gas, water, and other conduits that will be
crossed during excavation or other work must be
protected and supported, and the contractor must make
arrangements for their temporary removal and
replacement.
v. Excess material from the trench excavation shall be
located 600mm (minimum) away from the trench.
4 Sewag i. The Contractor must provide the S.O. with the approved
e drawings, system design, method of statement,
treatm structural, foundation, external work, and M & E work,
ent all of which must be duly certified by a Professional
system Engineer with Practicing Certificate (P.E.P.C.)
registered with the Board of Engineers Malaysia prior to
the installation of the sewage treatment system.
ii. Before being installed on site, sewage treatment systems
must need Local Authority/Certified Agency approval.
The Local Authority/Certified Agency must approve the
proposal in accordance with Appendix F/1.
Calculation for Population Equivalent (P.E) based on the guidelines that were provided
in the MS1228:1991. Calculations for Population Equivalent (P.E) for the proposed
project:

All streams from the additional building are channeled to the sewage treatment plant. The
proposed pipeline for the proposed reticulation system is a 225 mm (9 inch) VCP sewer pipe
that will drain sewage through the gravity stream with manure provided at each
intersection, direction change, pipe size change, gradient change at a maximum distance of
90 m. All building materials, minimum depths, gradients and sewage density are based on
guidelines by Jabatan Perkhidmatan Pembentungan (JPP) / Malaysia Standard MS 1228.
5. The Manning formula is used to determine the maximum velocity allowed by the pipe:
V = (1R2/3S1/2)/N
35
Perimeter Area
S = Gradient of pipe
R= 3.142r2
2 x 3.142 x (0.225)2
n = 0.009
S = 1/200
V = 1.15 m / sec
The allowed velocity range is within 0.91m/sec – 4.0m/sec, therefore the cutting
proposed was available.
Q = VA (1)
36
A = (3.142 d2) / 4
A = (3.14) x (0.225)2 / 4
A = 0.04 m2
= 46 liters / sec
Pipe capacity = 46 liters / sec > Peak speed capacity = 5.593 liters / sec

1.0 INTRODUCTION
This development has been developed based on the Development Order. The total area of this
development is 3.31 acre with water consumption estimated 35,000 lpd based on equivalent
population (EP) for water consumption for the proposed building. Table below shown the
demand per day for development.
This submission is to seek approval of communication pipe 150 mm Ø MSCL Pipe and meter
stand.
There are several criteria that were considered during designing of pipe reticulation as follows: -
a) Analysis of average flow for pipe reticulation will be checked with factor 1.0.
b) Analysis of peak flow for pipe reticulation will be checked with factor 2.5 (2.5 x average
flow).
c) Analysis of fire flow (hydrant) for pipe reticulation will be checked with the average
flow (1.0 factor) + 45lps (The hydrant involved at node 7).
d) The coefficient of friction is based on the formula of Hazen Williams roughness
coefficients (C) is 100 for Mild Steel Cement Linen/Ductile Iron pipe and 120 for
uPVC/multi layer uPVC pipe.
e) HSL for analysis peak flow refer to TWL of internal water tank for landed properties
(less than 15m height of building) and suction for high-rise.
40
f) HSL for analysis fire flow refer to platform level for landed properties (less than 15m
height of building) and high-rise.
g) Minimum residual pressure referred to HSL at each node is 7.5m.
h) The minimum allowable head loss in pipe due to friction is 2/1000 for peak flow and
15/1000 for fire flow.
i) Convey flows with a velocity of not less than 0.3 m/sec and maximum is 2.0m/sec for
average flow.
j) Minimum size for pipe reticulation is 150mm Ø.
k) All pipelines within an external reticulation system shall operate within a static pressure
not exceeding 30m at all conditions.
l) Water demand and design shall be based on the Uniform Technical Guideline for Water
Reticulation and Plumbing.
Based on the pressure test results received from Ranhill SAJ Sdn Bhd via letter reference
Bil(07)dlm.SAJ/KG/PEM/02-1661 dated 15 March 2020, the location of the pressure test is
estimated 1.0km away from the proposed connection point (location plan attached). Therefore,
here is available pressure at proposed connection point:-
Hostel
= 1.013 lps
Fire Hydrant
= 46.0.13 lps
Draw-off table for the analysis of pipe reticulation can be referring in hydraulic analysis
section. Based on available pressure, 70m that the water can be supply directly to the individual
tank.
5.0 CONCLUSION
Based on the results of hydraulic analysis, here are conclusions of this report:
1. The residual pressure refers to HSL for the peak and fire flow analysis shows the value
exceeding 7.5m.
2. The pressure head loss due to friction of the peak flow and fire flow analysis shows the
value less than 2/1000 and 15/1000.
3. Convey flows with a velocity of not less than 0.3 m/sec and maximum is 2.0m/sec for
average flow.

ROAD DESIGN
1.0 INTRODUCTION
Road design is the process of planning, construction, and maintenance of roads and highways.
It includes various factors like traffic flow, safety, accessibility and the surrounding
environment. The goal of road design is to create a transportation system that is efficient, safe,
and sustainable for all road users. This includes drivers, bicyclists, and pedestrians. Factors
such as road geometry, pavement materials, and road furniture are also important
considerations in road design.
The goal of this project is to propose road infrastructure for a hostel and dining hall in
Sekolah Menengah Kebangsaan Warisan Puteri in Jalan Sikamat, 70400 Seremban, Negeri
Sembilan. The focus is on creating access to be planned building, which includes the school
building, dining hall, students hostel and other facilities within the development. The main
purpose of the road construction is to connect the main road with the intended building area,
ensuring the people including students and teachers have easy access to the surrounding areas.
The local authority responsible for this project is Majlis Bandaraya Seremban. Overall, this
study is to provide an overview of the road design process, factors that are considered in it, and
design and detailing drawing of proposed road will be shown.
56
Sekolah Menengah Kebangsaan Warisan Puteri is located at Jalan Sikamat, Seremban, Negeri
Sembilan is required to construct suitable pavement that connected existing road to the project
site. After considering factors such as cost, time and quality, the most suitable type of pavement
chosen for the project is a flexible pavement. To select the type of pavement, several factors
must be taken into account. These include:
i. Traffic loading:
- Equivalent Standard Axle Load (ESAL) is used to convert wheel loads of
various magnitudes and repetitions to an equivalent number of standard loads.
The standard axle is defined as a Single Axle with Dual Tires (SADT) applying
an axle load of 80 kN (8160 kg) to the pavement (Austroad, 2012).
- Wheel configuration
- Volume and composition of axle loads
- Tyre pressure and contact area
ii. Environmental Factors:
- Temperature (hot and low), climate condition, and heavy rainfall must be taken
into account when selecting the type of pavement
iii. Material Characteristics:
- The Marshall Sample Test and California Bearing Ratio (CBR) test are used to
determine the strength characteristics of paving materials and subgrade
supporting load. These tests help to ensure that the chosen pavement will be
able to withstand the loads and pressure it will subject to.
Road Design Concept starts with the determination of the road function, which includes the
type of vehicle that will use the road, the Level of Service (LOS) required, and the design
speed. Others factor that need to consider such as alignment, cross section, and drainage to
create a functional and safe road.
Existing road refer to pre-existing roads that have already been built and are currently used.
When working on the existing roads, engineers must consider the existing infrastructure and
make sure that any new construction or improvement are consistent with the existing road
design and function. The width of existing road is 8.23 in meter and the proposed road width
is 6 meter.
57
Flexible pavement using Hot Mix Asphalt (HMA) pavement. It called ‘flexible’ since the total
pavement structure bends or flexes to accommodate traffic loads. Flexible pavement is made
up of several layers, also known as structural elements for roads, including the subgrade (soil),
sub-base (sand), base (aggregates), and surface layer (binder and wearing course). Dense-
graded, open-graded and gap graded are the types of flexible pavement. The pavement structure
for proposed road were following JKR Arahan Teknik (Jalan) 5/85 Pindaan 2013 as described
in following section.
In general, the thickness of road pavement is determined based on the strength of the subgrade
soil and the amount of road traffic will be expected to handle over a specific period of time.
The design of California Bearing Ratio is used as a measure of the ability of soil to support
load. The total number of 80 kN standard axle application, which is an industry standard for
measuring traffic loads is used to ensure that the pavement is thick enough to withstand the
expected amount of traffic over the design period. The design period of ten years used and it
refers to the span of time between the initial passing of user traffic until the fatigue limit of the
pavement whereby a strengthening overlay is required. The guide for equivalence factor
illustrated as shown in Table 4.1.

i) The initial annual commercial traffic for one direction, Vo is obtained by:
𝑉𝑜 = 𝐴𝐷𝑇 𝑥 0.5 𝑥 365 𝑥 𝑃𝐶/100 [1]
= 10950
ii) The total number of commercial for one direction (Vc) is obtained by:
Vc = Vo [ ( 1 + r ) x ] / r [2]
= 15.1 x 105
iii) The total equivalent Standard Axle (ESA) application is given by:
ESA = Vc x e [3]
= 1.81 x 106

C=IxRxT [4]
Where;
I is the ideal hourly capacity as in Table 3.2, JKR Method: Arahan Teknik (Jalan) 5/85
R is the roadway factor as in Table 3.3 JKR Method: Arahan Teknik (Jalan) 5/85
T is the traffic reduction factor in Table 3.4 JKR Method: Arahan Teknik (Jalan) 5/85

Flat T = 100/(100+Pc)
60
Rolling T = 100/(100+2Pc)
Mountainous T = 100/(100+5Pc)
Assuming that maximum hourly capacity is 10% daily capacity, then the one way daily
capacity is as follows:
C = 10 x c [5]
= 10 x 1124
= 11240 veh/day/lane
= 400 (1+0.07) 10 / 2
= 393 veh/day/lane
= C > Vx ∴ OK!
From fig.2, the chart shows that for an ESA of 1.81 x 106, the required TA’ is 20 cm.

The minimum thickness of a bituminous layer must be based on Table 3.8 (ATJ 5/85) in order
to prevent exceeding the critical tensile strain at the base of the layer. This table provides the
recommended thickness for the bituminous layer based on the type of traffic and the subgrade
soil conditions.

Pavement structure for traffic category is T2 which the ESA value is 1.81 x 10 6.
Road Signage or Traffic Sign discussed in this project are referring a standard of Arahan Teknik
(Jalan) 2A/85 – Standard Traffic Signs.
Road signage refers to the various signs, markers, and signals that are placed along a
roadway to provide information, guidance, and instruction to road users. These signs are used
to convey a wide range of information, including traffic regulations, speed limits, warning of
potential hazards, direction and guidance for navigation, and other important information.
There are several different types of road signs, each with a specific purpose and design.
i. Regulatory signs, such as stop signs, yield signs, and speed limit signs, are used to
communicate specific rules and regulations that drivers must follow.
ii. Warning signs, such as those that indicate sharp curves, construction ahead, and
animal crossings, are used to alert drivers to potential hazards on the road.
iii. Guide signs, such as those that indicate the distance to upcoming exits or
destinations, are used to provide drivers with information they need to navigate the
road.
67
iv. Informational signs, such as those that indicate the location of rest areas, gas
stations, and other services, are used to provide additional information to drivers.
In this project, the company provided road signage at the road to give a warning to road
users to be alert, careful while driving and ensure the satisfaction for road users when using the
road. There is some road signage that has been proposed:
Road Signage or Traffic Sign discussed in this project are referring a standard of Arahan Teknik
(Jalan) 2D/85 – Manual on Traffic Control Devices: Road Marking and Delineation.
Road marking is the process of applying lines, symbols, and other markings on the
surface of a roadway to provide guidance and information to drivers. These markings are used
to indicate traffic lanes, crosswalks, parking spaces, and other important features of the road.
It can be applied using paint, thermoplastic, and preformed tapes. Road markings serve several
important functions, such as:
69
i. Guiding drivers by clearly defining the boundaries of traffic lanes, crosswalks, and
other important areas of the road.
ii. Enhancing safety by providing drivers with clear visual cues that help to prevent
collisions and other accidents.
iii. Improving traffic flow by providing drivers with information they need to navigate
the road safely and efficiently.
Pavement markings are divided into longitudinal lines, transverse lines and other
markings. Firstly, in general, a longitudinal line shall consist of either an unbroken or a broken
line or a combination of both marked in the direction of travel. Each of it have different
function, the broken line is used to separate moving vehicle where there is unrestricted visibility
and may be crossed at the discretion of drivers. Meanwhile, the single unbroken line is used
where the crossing of the line is to be discouraged or is legally prohibited. Figure 4.4 illustrated
the dimensions of longitudinal lines for rural areas.
Next, transverse lines are lines that cross across the road and are usually associated with
intersection or junction controls or traffic signals. Because of the narrowing caused by the low
angle at which they are viewed, transverse lines should be wider than longitudinal lines.
Transverse line consists of stop line, holding line or give way line, and pedestrian crossing
marking. Lastly, other marking is defining splayed island approaches, or obstructions, sealed
shoulders, painted island and medians and areas separating exit ramps from the carriageway.
