EXECUTIVE SUMMARY
This chapter reports on the areas of harmonization of traffic signs in the EAC member states.
Traffic signs include road signs, traffic signals (traffic lights), and road markings. They are usedby road authorities to communicate with road users with view to regulate their behaviour, to
guide, warn or inform them for their own safety and convenience on the public road networks.
International conventions provide a framework for traffic signs and each member state has
adopted a set of traffic signs to meet their current needs through their traffic law and/or traffic
signs manual. Traffic signs regulations and manuals keep evolving to meet the needs of the
travelling public. The harmonization of traffic signs in the EAC is essential to the safety and
convenience of the public travelling on the road networks whether for trade, tourism, education
or other purposes.
The main recommendation of this chapter is to integrate the existing road traffic signs and roadmarking schedules of the member states and adopt any additional signs deemed appropriate.
Burundi recently commissioned a consultant to undertake a review of her traffic signs and it is
understood at the time of writing a report has been submitted and the government is considering
the recommendations. We recommend that the government consider the recommendations in
the light of the need for harmonization indicated herein. In the few cases where there were
differences in practice between the member states we have recommended adoption of a road
traffic sign or marking that agrees with the SADC-RTSM. Each member state should develop
and publish its road traffic signs manual. This will facilitate the harmonization of the more
technical aspects of road signing which are provided for generally in the law.
A prudent implementation of approved changes is recommended whereby the adopted signsand designs are applied on all new and rehabilitation projects and in the course of maintenance
of road signs. No special budget will be required if this approach is approved.
ROAD SIGNS
Generally there exists no big difference in the use of road signs in the member states. To
ensure greater uniformity in the installation of road signs the following are recommended.
i. The guidance on mounting and placement by member state manuals should be more
explicit to reduce differences and achieve greater convenience of road users.
Specifically guidance for placement and sign plate sizes for roads with different designspeeds should be explicitly be stated. Recommendations are included in this chapter.
ii. The member states regulatory signs schedules are generally similar and the differences
are complementary and not conflicting. It is recommended to integrate the existing
regulatory signs schedule. Additional signs may be adopted from SADC RTSM.
iii. Warning signs schedules current in member states be integrated including temporary
warning signs.

PREPARATION OF THE EAST AFRICAN TRANSPORT FACILITATION STRATEGY
BUREAU FOR INDUSTRIAL COOPERATION Chapter 7 page 6
iv. Guidance and information signs schedule current in member states be integrated and
enriched by adopting additional signs from the RTSM (SADC).
v. Appropriate regulatory and warning signs be used as temporary signs at road works.
vi. Road authorities in member states should adopt management practices that will ensure
consistent application and maintenance of road signs at all relevant locations at all
times.
ROAD MARKINGS
The use of pavement markings in the member states is generally similar and the minor
differences that exist should be harmonized by conforming to the SADC guide. In this regard
some member states will need to replace the use yellow line used to prohibit overtaking in
favour of white line. This provides for greater uniformity and has economical and technical
advantages since the application of white line is cheaper and has better retro-reflectivity. Since
there are circumstances which may require installation of road studs for better visibility, member
states should be encouraged to adopt their use formally.
TRAFFIC SIGNALS
There are no major differences in the regulations for operation of traffic signals in the member
states. The meaning of the lights and sequencing are generally consistent and road users can
quickly adapt to the slight differences that exist. However, phasing out of traffic signals based on
only the red and green light (two lights system) is desirable. The installation of two sets of signal
heads per approach, one set on the near side of the approach and the other set at the far side
of the approach is desirable especially on arterial road junctions. It is of utmost importance that
junctions with similar traffic conditions be controlled in a uniform manner in the interest of
consistency and developing respect for traffic signs. Signals should therefore be installed wherean engineering study confirms that their installation is warranted. The process should be guided
by competent professional on the basis of current best practices especially the guidance
provided in SADC-RTSM.
TRAFFIC SIGNS FOR SCHOOL ZONES AND FOR PEDESTRIANS WITH SPECIAL NEEDS
The practice of developing school route plan, defining school zones and the necessary traffic
signing around schools both in urban and rural areas is recommended for adoption by member
states as means of providing for safety and convenience of school children when walking to
school within school zones. The needs of physically challenged road users should also be
provided through proper signing and road design.
SIGNING FOR TRAFFIC CALMING
The need for traffic calming across the member states is being met without the benefit of a
systematic approach involving both the professionals and the public. Sometimes the traffic
signing is not adequate and the measures are not visible to the road users. Harmonization of
the planning, signing and design of traffic calming measures is recommended.

7.1 INTRODUCTION
7.1.1 Background
This paper addresses a part of thematic area one, namely: Harmonisation of Standards
and Specifications. This chapter addresses the sixth component: harmonisation of road
signs, traffic signals and markings. For the purpose of this chapter traffic signs include
road signs, traffic signals and markings; sometimes referred to as traffic control devices
(TCD). The paper thus presents a review of the legal traffic signs and recommended
practices in the member states and identifies areas requiring harmonization.
7.1.2 ObjectiveThe objective of this chapter is to make recommendations for the “Harmonisation of
Road Signs, Traffic Signals and Markings” as spelt out in the ToR.
7.1.3 Methods
Methods adopted for the study included the review of member state and best practices
documents in order to identify areas of harmonization and improvement and interaction
with stakeholders and experts in the member states to get their view on the proposals.
7.2 ROAD SIGNS
The following paragraphs summarize legal requirements for road signs, recommendations in
current manuals and suggest the way forward where harmonization is required.
7.2.1 Placement and Mounting of Road Signs
The following general advice on sign mounting and positioning is recommended though it might
not be possible to follow the advice exactly due to site constraints:
Check that the signs are clearly visible from the appropriate distance Check that there is no confusion about which road the sign refers to
Check that signs do not obstruct the view of drivers, especially at junctions
Check that the signs are not placed where they could be struck by vehicles
Placement
Signs on two-lane roads should be placed on the side of the road on which the traffic it is
intended to control is using except on sharp bends where signs placement on the other side will

make it more visible. On dual carriageway roads warning and regulatory signs should be
installed in pairs, one on the left-hand and another on the median. The table below relates the
approach speed to the required visibility.
Approach speed
(km/h)
Visibility distance
to the sign (m)≤ 60 km/h 60
80 km/h 80
≥ 100 km/hr 100 – 150
The GTS further recommended that, if two signs are to be placed at the same place they should
be spaced at least V metres apart (where V is the approach speed in km/h) to avoid obscurity.
In Rwanda (driving in the right) the requirement is to place signs on the right side of the road.
The warning (danger) signs must be place 150 m to 200 m from the dangerous area. An
additional panel should be used to indicate the distance to the dangerous location if it is not
practical to place the sign at 150 to 200 m from it.
Mounting
Heights and side Clearances
Recommended mounting heights are given in Table 2 in the MoID – GTS. The
recommended standard mounting height is 2100 mm from the lowest edge of the sign
plate to the road surface. The law in Rwanda specifies a minimum height of 1.50 m and
not more than 2.10 m above the ground (Article 92).
Multiple Signs / Secondary Message Signs
The RTSM and the GTS recommend that a secondary sign to be mounted beneath the primary
sign to which it refers, and when two or more warning signs are mounted on the same sign pole
the sign at the top should refer to the nearest of the hazards. When appropriate it is better to
place the secondary message signs on the same sign plate as the primary sign (stronger plate,
less chance for vandalism).
Angle o f the Sign Plate
The recommended sign plate angle in the RTSM is 93 0 to the direction of travel in order to avoid
mirror-like glare when the sign is illuminated by vehicle headlights.
Placement and mounting requirements can be summarized as follows:i. To adopt standard height of the bottom border of a sign at 2.10 m above the ground and
to allow greater heights if it is necessary to achieve visibility of the sign.
ii. Mounting of secondary sign below the primary sign be accepted where it is not a
standard practice.
iii. Adopt mounting angle (930) to the direction of travel.
iv. Required visibility to be equal to or greater than the design speed of the road.

7.2.2 Regulatory Signs
Use and Classification
Regulatory signs are used to control the actions of road users in the interest of safety and the
efficient use of road space. The table below shows the classification of regulatory signs.

Command Instruct drivers what to do R103 – R137
ProhibitionInstruct drivers what they mustnot do
R201 – R245
ReservationReserve road space for specificvehicle types
R301 – R360
Temporary Signs
The colours of the Control Group of signs such as STOP sign should not change when the sign
is used on a temporary basis, but the background of command, prohibition and reservation
group sign when are used for temporary restrictions such as at roadwork should be yellow. The
table below shows the colour code for temporary regulatory signs.
Command Group Prohibition Group Reservation Group
Border Black Red Black
Background Yellow Yellow Yellow
Symbol Black Black Black
End of a Restriction
The GTS and the Traffic Act Regulations (Kenya) superimpose four black diagonal bars on a
grey version of the restriction sign.
Placement and Sizes
In general regulatory sign should be sited on the side of the road the traffic is using at or near
the point where the instruction applies. The Table below gives the recommended sizes for
standard regulatory signs given in the Kenya Traffic Act (Regulations, Revised edition 2009)and the GTS.

The general principle of using dimensions corresponding with the design speed should be
adopted in this case.
The GTS recommends reduced signs for the following circumstances:
- Signs on traffic signal heads – 300 mm diameter- Keep Left signs on traffic bollards – 300 mm diameter
- Parking signs – 450 mm diameter and 450 x 340 mm
Schedule of Regulatory Signs
Annex 1: Schedule of regulatory signs shows that many signs are common and member states’
schedules are complimentary. Adoption of few additional signs from the SADC-RTSM is
appropriate.
7.2.3 Warning Signs
Use and Classification
Warning signs are used to alert drivers to danger or potential danger ahead. The Rwanda
Traffic law and the GTS listed two groups of warning signs:
Group Description Proposed Sign numbers
Advance Warning SignsRoad Layout W100 Series
Movement W200 Series
Symbol W300 Series
Hazard Marker Signs Curve and object markers W400 Series
Supplementary plates may be used underneath the primary sign.
Temporary Signs
The GTS provides for the use of warning signs in temporary situations. When they are used in
such situations they should have yellow backgrounds instead of white background. The
following signs have been documented in the manual for use in temporary situations:

Placement and Sizes
The following Table gives the sitting distances and sizes of standard warning signs for different
traffic speeds as recommended in the GTS (based on SADC-RTSM). The Kenya Traffic Act
Traffic Signs Regulations - KTSR) requires a warning signs length to be not less than 700 mm.

Schedule of Warning Signs
Annex 2 presents the integrated schedules of warning signs from the member states with few
additions from the SADC-RTSM. Member states need to adopt signs not currently in use in their
jurisdiction as shown. Their dimension should match the design speed of a given road as shown
above.
7.2.4 Guidance Signs
Use and Classification
Guidance signs give road users information on how to find their way to their destination. The
SADC-RTSM classified guidance signs into five groups as shown below:

Direction Signs – Types and Placement
The SADC-RTSM elaborates on guidance signs as shown below:
Types of Signs Description
Advance direction signs (GD1, GD5, GD8) They are used to give route information to
drivers approaching a junction
Direction signs (GD2, GD4) They are used to give route information at the
junction and often point along the route
referred to
Confirmation signs (GD3) These list the destinations ahead, and are
placed about 100 m after important junctions,
and at intervals along the road.
Recommended placement of advance direction signs (GD1, GD5, GD8) in the GTS are as
shown below:
Approach speedDistance of sign from
junction (m)
≤ 60 km/h 50 - 90
80 km/h 90 - 150
≥ 100 km/h 150 - 220
Sizes and design princ iples
To avoid confusion limit the number of destinations to four per sign. In one direction limit the
number of destinations to two with the nearest one at the top. The size of the sign depends on
the amount of text. Typically letter sizes depend on the approach speed as shown below.

Member states need to adopt the SADC-RTSM approach and schedule of Guidance Signs as
shown in Annex 3.
7.2.5 Information Signs
Use and classification
Information sign may take the form of a supplementary plate that provides additional information
to that given on the primary sign or to indicate the presence of an information center or other
facility.
Sizes and design princ iples
SADC-RTSM recommends:
Supplementary signs Recommended sizes/colour

Width of Supplementary plates Should match that of the primary sign
Capital letter height size 140 mm
Lower case letter height 100 mm
Cul-de-sac 600 mm (h) by 450 mm (w)
When the supplementary plate is to be used with a small sign such as a 600 mm diameter regulatory
sign the text size may be reduced to 112 mm/80 mm
Schedule of information signs
Annex 4 provides a sample of signs to be included in a schedule of information signs. Member
states should decide on adequate schedule for their current needs and derive it from the SADC-
RTSM.

BUREAU FOR INDUSTRIAL COOPERATION Chapter 7 page 14
7.2.6 Signing at Road Works
The need for appropriate signing of road works is recognized in the laws of the member states
and the RTSM – SADC.
Generally regulatory and warning signs are adopted for road works by using backgrounds
recommended for temporary signs. Advance warning signs and appropriate regulatory signs
should be used. Markers may also be used as appropriate. Appropriate signs and markers are
included in the regulatory and warning signs schedules.
Maintenance manuals and specifications for road works in member states provide instructions
and those supervising the works are to ensure compliance.
7.2.7 Traff ic Sign Materials and Manufacture
The following is recommended practice.
Sign Face Materials
All traffic sign, permanent and temporary, should be fully reflectorized by making the sign face
from retroreflective sheeting. Symbols or letters coloured black are recommended to be made
from black non-reflective overlay film.
Sign Plate
Use of aluminium alloy sheet is recommended due to its resistance to corrosion. Sincealuminium alloy sheets are expensive cheaper alternatives such as galvanized steel, plastic-
coated steel or steel treated with primer. The back of the sign plate be painted grey, and the
sign manufacturer’s name and the date of manufacture be permanently marked on it.
Sign Support Frame and Fastenings
The sign plate should be fixed to a back support frame made of angle iron or aluminium
sections. All frames, brackets, clips, rivets, nuts, bolts and washers are corrosion-proofed if not
made of aluminium or stainless steel. The frames and brackets are recommended to be painted
grey.
Sign Post
Sign posts are recommended to be made of galvanized steel tube set in concrete foundations.
Road Sign Specifications
Member states provide specifications road signs through their specifications for road works
regarding the manufacture and installation of road signs.

BUREAU FOR INDUSTRIAL COOPERATION Chapter 7 page 15
7.2.8 Road Signs Management
In addition to the considerations for design, placement and materials for road signs there are
additional issues that should be addressed by road authorities to ensure uniformity in control of
traffic:
I. To make sure that every location that needs a traffic signs is provide with an appropriate
sign,
II. To ensure that where a sign is no longer needed it is removed,
III. To take precautions against theft for example by mounting the sign plate high up out of
easy reach, spot-weld the nuts onto the fixing bolts, and fill the posts with concrete or
approved vandalism proof materials are used and
IV. To ensure that signs are properly maintained and visible.
To ensure uniformity in the installation of road signs in the member states the following are
recommended.
vii. The guidance on mounting and placement by member state manuals should be more
explicit to assure uniformity hence convenience of the users. Specifically guidance for
placement and sign plate sizes for roads with different design speeds should be explicitly
be stated as illustrated
viii. The member states regulatory and warning signs schedules are generally similar and
the differences are complementary. It is recommended to integrate the existing
regulatory signs schedule as shown in the annexes.
ix. Guidance and information signs schedule current in member states be integrated and
enriched by adopting additional signs from the SADC-RTSM
x. Appropriate regulatory and warning signs be used as temporary signs at road works. xi. Road authorities in member states should adopt management practices that will ensure
consistent application and maintenance of road signs at all relevant locations at all
times.
xii. Burundi is currently evaluating a report on traffic signs and the proposals are not
included in the annexes. We recommend that the recommendations for harmonization in
this chapter be considered for their adoption.
7.3 PAVEMENT MARKINGS
7.3.1 Purpose and Classification
Road markings are used to control, warn, or guide road users and may be classified as follows:
8/20/2019 Chapter 7_Traffic Signs, Markings and Signals
16/64
PREPARATION OF THE EAST AFRICAN TRANSPORT FACILITATION STRATEGY
BUREAU FOR INDUSTRIAL COOPERATION Chapter 7 page 16
Road Markings Types
Longitudinal Lines Center lines, edge lines
Transverse lines Stop lines, and give way lines
Others Arrows, Symbols, Patterns and Words
7.3.2 Design Principles and Sizes
Road markings should be considered in detail at the design stage of new or improved roads and
junctions.
Requirements for road markings include:
Good visibility by day and night
Good skid resistance
Durability
Clarity of message
Symbols and words should be elongated in the direction of traffic by a factor of threetimes whilst retaining the original width.
Meaning assigned to centre-line and lane markings on pavement surface by regulations in the
member states and in SADC-RTSM:
Broken longitudinal lines are permissive (overtaking / lane change permitted)
Continuous solid longitudinal lines are restrictive (prohibit overtaking / lane-change)
Double continuous solid longitudinal lines indicate maximum levels of restriction
The width of the line is an indication of the degree of emphasis attached to the marking

7.3.3 No Overtaking Lines and Pavement Marking Schedule
These are continuous white lines (yellow in Kenya and Uganda) which imposes a mandatory
requirement that drivers keep the line to their right (driving on the left) unless when turning into
or out of a side access. The lines are provided at places with limited sight distances or other

The recommended minimum length of overtaking line on vertical and horizontal curves is 150 m
and the absolute recommended minimum distance between successive overtaking lines is 120
m. when used on the approach to junctions a minimum length of 24 m is recommended andmay be increase to 60 m or more at higher traffic speeds. No overtaking lines will be termed as
No crossing lines when two of these lines are used one for each direction of traffic.
It was noted above that SADC-RTSM use the white line to prohibit overtaking. This is practiced
in Burundi, Rwanda and Tanzania (Mainland and Zanzibar) while Kenya and Uganda use the
practice is to use the yellow colour. It is in the interest of uniformity within the member states
and SADC block to adopt the white solid line to prohibit overtaking. Some technical reasons for
this recommendation are summarized in the next section.
Pavement Markings Schedule
Annex 5 presents pavement markings in common use in the member states except for the
yellow line to prohibit overtaking as used in Kenya and Uganda. We recommend harmonization
to adopt white line as per SADC-RTSM.
7.3.4 Why Adopt White Solid Line to Prohibit Overtaking
It was recommended above that white lines be adopted by EAC member states for prohibiting
overtaking. Two practical reasons were given: to achieve uniformity within the member states
with regard to this practice and to conform to the practice in SADC countries. The secondreason is motivated by the fact that there is already a move to harmonize the three trading
regions – COMESA, EAC and SADC.
From the historical perspective, according Hawakins et al (2002), MUTCD (USA) required the
use of the yellow markings to separate traffic travelling in opposite directions in 1971. However,
USA has been considering the option of using all-white pavement marking system used in most
8/20/2019 Chapter 7_Traffic Signs, Markings and Signals

PREPARATION OF THE EAST AFRICAN TRANSPORT FACILITATION STRATEGY
BUREAU FOR INDUSTRIAL COOPERATION Chapter 7 page 19
industrialized countries. The technical advantages of using white pavement markings over the
yellow line identified in the report by Hawkins et al (2002) and relevant to our situation included:
i. All other factors being equal, white markings have higher retro-reflectivity than yellow
markings, and
ii. Some of the pigments used in yellow markings are difficult to recognize as yellow innighttime conditions.
In addition, white markings are cheaper than white markings.
Considering that drivers understand the use of solid line to indicate as prohibitive it will not be
necessary to remove the yellow lines immediately but allow their use till the end of their useful
life when they will be replaced by white marking. Their replacement will therefore be done at no
additional cost.
7.3.5 Marking at Junctions
Guidance on application of marking principles on un-signalized and signalized junctions is
offered in RTSM – SADC. We recommend the adoption of the guidance offered by the member
states as this will fill a gap in most member states.
7.3.6 Pavement Marking Materials
General guidance:
Road Paint: Use paint which dry quickly, durable and have good skid resistance.
Thermoplastic: Hot-applied thermoplastic is the preferred marking materials.
Reflectorization: Road markings materials should be reflectorized by the addition of reflecting
glass beads.
Specifications:
Road works specifications in the member states should specify materials that will ensure
durability especially for road with heavy traffic, visibility and good skid resistance.
7.3.7 Road studs
Use of road studs
Some member states have clear regulation on the use of road studs. Because of their cost, road
studs are generally used under the following conditions:
Frequent mist, fog or rain (making it difficult to see the road markings)
Poor visibility due to glare from headlights of oncoming vehicles
Difficult alignment (e.g. roads with many bends, some of which may be hard to see)
Roadside hazards (e.g. reduced carriageway width or limited clearance to obstacles)
Other hazardous sites.
8/20/2019 Chapter 7_Traffic Signs, Markings and Signals
20/64
PREPARATION OF THE EAST AFRICAN TRANSPORT FACILITATION STRATEGY
BUREAU FOR INDUSTRIAL COOPERATION Chapter 7 page 20
It is advisable to use road studs where they may reduce hazard to travellers. The following
guidance should be adopted.
Colour and Spacing
Recommended colour and spacing:
RED – for Prohibition YELLOW – for Warning
WHITE – for Guidance
The following table shows the recommended spacing of road studs on continuous lines and
dividing line:
Lines Spacing
No Overtaking Lines Rural areas: 24 m
Urban areas: 18 m
Edge Lines Rural areas: 24 m and 50 mm away from the lineUrban areas: 18 m and 50 mm away from the line
Diving Line Every second gap
The GTS recommended road studs to be aligned with the pavement markings and be placed
between lines for parallel lines and should never be use on transverse markings since they
could undermine vehicle’s stopping ability and are hazardous to two-wheeled vehicles.
Specifications
Road works specification should specify the standards to be adopted. It should be noted that if
the type of bonding adopted can be undermined by pavement markings then they should not be
installed on top of road markings.
7.3.8 Summary
The use of pavement markings in the member states is generally similar and the minor
differences that exist should be harmonized by conforming to the SADC guide. In this regard
some member states will need to replace the use yellow line to prohibit overtaking in favour of
white line. The details including line width, length of lines and gaps are given above. Since there
are circumstances which may require installation of road studs for better visibility, member
countries should be encouraged to adopt their use.

7.4 TRAFFIC SIGNALS
7.4.1 Purpose, Meaning and Use
The purpose of traffic signals is to provide positive control of vehicular and pedestrians at road
junctions, pedestrian crossings, multilane roadways and railway crossings.
The assignment of right of way is by green light illumination while the right of way is denied by a
red signal. Usually an amber (yellow) illumination is shown as a transition from green time to red
time. The meanings of the traffic signal indications under the three colour system described
above and for pedestrian signals are given in Annex 6. Two light system is also in use where
the amber is replaced simultaneous illumination of both the red and green light.
It is highly desirable to ensure uniform usage of traffic signals so that similar traffic conditions
are controlled in a consistent manner. This encourages compliance and achieves higher safetylevel. The basis for installation or removal of traffic signals in the member states and their
placement is therefore proposed below.
7.4.2 Basis for Installation or Removal of Traffic Signal
Traffic signal control should only be installed when an engineering study of traffic and roadway
conditions at the intersections confirms that a signal control is warranted. The decision is based
on careful analysis of traffic operations and needs of pedestrians and cyclists at many
signalized and un-signalized road junctions combined with engineering judgement which
resulted in a series of warrants defining minimum conditions under which signalization might be justified. To ensure uniformity signalized intersections which no longer meet the minimum
conditions should have their signals removed.
It is important for junctions with similar conditions within the EAC to be controlled in the same
way for the interest of uniformity. The requirements for design and installation of traffic signals
set out in the RTSM (SADC) should be adopted by the member states.
7.4.3 Design Principles
Generally signals are used to control traffic at warranted junctions in built-up areas on roads
with speed limit of 50 km/hr. When used on roads with higher speed limits (up to 70 km/hr and
rarely 80 km/hr) advance warning signs are used, visibility should be excellent, all right turning
movements should be fully protected and at least one signal on each high speed approach
should be mounted overhead. The following good practice guidance on the mounting and
positioning of signals at junctions, pedestrian crossings and railway crossings are consistent
8/20/2019 Chapter 7_Traffic Signs, Markings and Signals
22/64
PREPARATION OF THE EAST AFRICAN TRANSPORT FACILITATION STRATEGY
BUREAU FOR INDUSTRIAL COOPERATION Chapter 7 page 22
with the requirements of the member state documents. Where exceptions occur in practice
improvement is recommended.
Location of
the signal
Description
Signals at
junc tions
Signal head should be mounted on a post at the side of the road. The clearance ofthe signal heads from the road surface should be 2.3 m to 3m.
The signals should be mounted vertically with the red signal at the top, yellow at
the middle and green at the bottom with the lenses protected from direct sunlight
by hoods.
Signal head should not be within 500mm of the kerb face
Signal lens diameter should not be less than 200 millimetres and no more than 300
millimetres.
The unit casing should be painted black or grey and the post should be painted
grey.
Overhead signals clearance height above the road surface not be less than 5.2 m.
Install two signal heads per approach, one on the near side of the junction and
another on the far side.
The distance between the centres of the lenses not to be more than 400
millimetres apart.
Sequence of the lights
i. Red
ii. Red and amber/yellow (optional)
iii. Green
iv. amber
Signal heads should be visible from at least 80 m for 50 km/hr approaches and
110 m if the traffic speed is more than 50 km/h
Pedestrian
signals
The signals should be arranged vertically with the red standing man signal at the
top and the green walking man at the bottom and illuminated separately.The signal lens diameter should not be less than 200 mill imetres and no more than
300 millimetres
Signal head clearance should not be less than 2.1 m and not more than 2.6m.
Signals at
Railway
Crossing
The signal lens diameter should at least be 200mm
Signal should be positioned within 5 - 10 m of the nearest rail line.
Signal should be mounted at the left hand side of the road or above the
carriageway
There are no major differences in the regulations for operation of traffic signals in the member
states. The meaning of the lights and sequencing are generally consistent and road users can
quickly adapt to the slight differences that exist. However, phasing out of traffic signals based ononly the red and green light (two lights system) is desirable. The installation of two sets of signal
heads per approach, one set on the near side of the approach and the other set at the far side
of the approach is desirable especially on arterial road junctions. It is of utmost importance that
junctions with similar traffic conditions be controlled in a uniform manner in the interest of
consistency and developing respect for traffic signs. Signals should therefore be installed where
an engineering study confirms that their installation is warranted. The process should be guided
by a competent professional on the basis of current best practices.

7.5 Traffic Signs for School Zones and Pedestrians with
Special Needs
7.5.1 GeneralSchool going children constitute significant proportion of the population of any country and
require specific attention for schools in urban centres or in rural areas where school route
crosses a major road. It is important that similar traffic situations are treated in the same manner
for the interest of uniformity. Generally school crossing are not addressing very specifically in
the existing guides or regulations but their needs are assumed to be met within the existing
framework of road signing.
We recommend that for interest of uniformity schools crossing be managed in similar manner
within the member states. Schools, traffic police and respective road agency should develop a
school route plan consisting of a map showing streets, the school, existing traffic signs, school
routes and crossings. The types of school traffic signs to be used should depend on the volumeand speed of traffic, street width and the age and number of children using the crossing. The
following sections describe road signs, pavement markings, traffic signals, supervised crossing
and grade separation that might be used in school zones. In addition, the use of calming
measures should be carefully considered in areas where driver compliance to school zone
regulatory signs is low.
The practice of developing school route plan, defining school zones and the necessary traffic
signing around schools both in urban and rural areas is recommended for adoption by member
states as means of providing for safety and convenience of school children when walking within
school zones.
7.5.2 Road Signs
School signs shall be place where they will convey their message most effectively without
restricting sight distance or being in danger of being hit by errant vehicles and generally comply
with requirements for regulatory or warning signs.
The following school signs are proposed:
i. School advance warning sign
ii. School bus stop aheadiii. Reduced speed school zone ahead
iv. School speed limit (30 km/hr)
v. End of school zone
The signs are to be integrated in the regulatory and warning signs schedule.
8/20/2019 Chapter 7_Traffic Signs, Markings and Signals
24/64
PREPARATION OF THE EAST AFRICAN TRANSPORT FACILITATION STRATEGY
BUREAU FOR INDUSTRIAL COOPERATION Chapter 7 page 24
7.5.3 Pavement Markings
The standard pavement markings can be used effectively in the context of a school zone. Word
message may be used to complement mandatory signs or as information. In particular, the word
“SCHOOL” should be written across a lane(s) between the stop line and the zebra lines of a
crossing within a school zone.
7.5.4 Traff ic Signals
Where adequate gaps in traffic stream in a school zone are few the resulting delay may tempt
scholars to endanger themselves by attempting to cross using an insufficient gap in. Under such
circumstances it may be appropriate to consider installation pedestrian signal. The signal may
be installed if an engineering study confirms that there is sufficient justification, for example by
demonstrating that the warrant for installation of school crossing signal according to the MUTCD
is mate.
7.5.5 Supervised Crossing
Supervised crossing is needed where gaps are not sufficient and need to be created by an adult
who is mandated to stop vehicular traffic to allow pedestrians to cross. The following practice is
recommended:
i. Uniform of the guard: high-visibility retro-reflective safety clothing marked STW (School
Traffic Warden) on the back.
ii. Use of STOP paddle as a hand signaling device.
iii. Selection of school traffic warden shall ensure that people of at least average
intelligence, with sense of responsibility for safety of school children and are respectable
are assigned the responsibility of supervising a school crossing.
iv. The school shall have primary responsibility for the appointment of a school trafficwarden but shall consult with the traffic police and the respective road authority.
v. The hours that a school crossing needs to be supervised shall be agreed between the
school, traffic police and the respective road authority.
7.5.6 Grade Separated Crossings
A grade separated facility may be appropriate means of physically separating school children
from vehicular traffic. Generally pedestrians prefer to cross at grade and grade separated facility
should be considered when road design type or traffic volume and speed is demonstrated by an
engineering study to favour a grade separation. An over pass is easier to maintain and
supervise than an under pass and therefore should be preferred unless topography is
particularly favourable for an underpass. Grade separated facility may require the use of
barriers to prevent pedestrians from crossing at grade.
7.5.7 Pedestrians with Special Needs
Pedestrians with special needs include the physically challenged road users including those
with poor vision, those who cannot hear and those with impaired mobility capabilities. There is a
need to warn other road users regarding their presence on a particular location so they can
8/20/2019 Chapter 7_Traffic Signs, Markings and Signals
25/64
PREPARATION OF THE EAST AFRICAN TRANSPORT FACILITATION STRATEGY
BUREAU FOR INDUSTRIAL COOPERATION Chapter 7 page 25
exercise extra caution. We recommend including appropriate signs the schedules (regulatory
and warning signs). The provision of audible sound at signalized intersections should be used to
alert those who cannot see the pedestrian signal when it is time to cross. Road design should
include tactile surfaces to alert pedestrians with poor vision regarding the presence of a
crossing facility.
7.6 SIGNING FOR TRAFFIC CALMING
7.6.1 Introduction
The principle goal of traffic calming is to improve traffic safety and the living environment by
moderating traffic behaviour through physical and legislative measures aimed at reducing
vehicle speeds and/or traffic volumes whilst giving due regard to mobility and accessibility
requirements. It has to be borne in mind that the road signs and markings are used when
implementing traffic calming measures and these signs generally fall into the regulatory,warning and information signs.
There is a great need to harmonize the applications of traffic calming in the members states in
order to do away with the haphazard applications in favour of a systematic approach that
ensures uniformity and the achievement of the intended purpose with due regard to the needs
of all road users and the general public.
7.6.2 Types of Traffic Calming Measures
The types are categorized in terms of measures located at intersections, those located between
intersections and area-wide measures.
Measures located at intersections
Traffic calming measures applied at intersections are primarily aimed at reducing speed into the
road or limiting or removing access movements. These measures are:
Mini-roundabouts;
Raised intersections;
Intersection diverters;
Street closures; Intersection narrowing.
Measures located between intersections
The objective of traffic calming measures applied between intersections is to reduce vehicle
speeds. The commonly used calming measures include:
Speed humps/tables;
8/20/2019 Chapter 7_Traffic Signs, Markings and Signals
26/64
PREPARATION OF THE EAST AFRICAN TRANSPORT FACILITATION STRATEGY
BUREAU FOR INDUSTRIAL COOPERATION Chapter 7 page 26
Chicanes, pinch points or chokers;
Rumble strips;
Carriageway narrowing;
Pedestrian crossing table;
Area-wide measures
Area-wide measures include the following applications of traffic calming:
The Woonerf – this means “shared space” which is a concept rather than a specific
traffic calming measure.
More traditional general treatment such as one way systems: the systems are applied to
eliminate through traffic movements and to reduce vehicle speeds.
7.6.3 Planning for Traffic Calming
Traffic Calming Objectives and Planning Overview
In achieving the goal of traffic calming measures as defined above, the objective is not to
exclude traffic but rather to manage and moderate its behavior by ensuring no significant
reduction of accessibility and mobility of pedestrians. To address the problem associated with
the introduction of traffic calming measures, there is a need to identify planning aspects which
need to be considered when considering the introduction of the traffic calming concept and
ensure appropriate study work is undertaken prior to considering their introduction.
Traffic Calming Study Requirements
To evaluate and conclude whether the requests from residential groups for implementation of
traffic calming measures are justified or unjustified, there is a need to ensure that a proper andsufficiently comprehensive traffic/transport study is undertaken.
Public Involvement
To have a good point for implementation of traffic calming measures, the involvement of public
is necessary as are the residents who know or have knowledge of their area, in terms of its
traffic issues and bring concepts of problem area to the study team. In identifying who should be
included in the public involvement, the following proposed list may assist in the identification of
potential role players:
Neighbourhood resident groups/associations;
Adjacent resident groups/associations;
Local Authority within which the neighbourhood is situated;
Adjacent Local Authorities;
National Road Authority when applicable;
Representation from Emergency Services;
Representation from the business sector, commerce and industry etc. when applicable;
Representation from the private transport sector and from the authorities, operators and
users of other transport modes if applicable.
8/20/2019 Chapter 7_Traffic Signs, Markings and Signals
27/64
PREPARATION OF THE EAST AFRICAN TRANSPORT FACILITATION STRATEGY
BUREAU FOR INDUSTRIAL COOPERATION Chapter 7 page 27
Study Requirements
Before introducing traffic calming measures, studies must be undertaken which will address and
where applicable, collect reliable information on:
The precise concerns of residents (through traffic, speed, noise, accidents etc);
The magnitude of the problem; The origins and destinations of the external traffic;
An examination and analysis of the roads at the “correct” location;
Travel times through the residential neighbourhood;
The identification of other routes/roads which have the potential to be impacted should
traffic calming measures be introduced;
The implications on residents should traffic calming measures be introduced;
The implication beyond the bounds of one neighbourhood;
Emergency vehicle access requirements;
Public transport implications.
7.6.4 Traffic Calming Sign Applications
Although road traffic signs related to traffic calming for example speed hump are prescribed in
the Road Traffic Act and many other regulatory, warning and information signs and marking of
the member states, which can be utilized when introducing traffic calming measures, however
there is a need to prescribe the additional traffic calming related signs. The table below presents
the checklist when the need for implementation of roundabouts, speed humps, chicanes/pinch
points and raised intersections is under consideration:
Type of Traffic Calming Measure checklist s
Mini-roundabout
- Is any mini-roundabout in the area difficult to see,
either by day or by night?
- Is the use of retroreflective road studs advisable?
Speed Humps
- Does street lighting exist in the area?
- Is the speed hump an isolated one or part of an
area traffic calming treatment?
- Is the speed hump part of a traffic calming
treatment involving a range of different traffic
calming measures?
- Is the speed hump a flat top hump which is used
as a pedestrian crossing?
Chicanes or Pinch Points
- Are peak hour traffic volumes under 600 vehicles
per hour?
- Is the area adequately illuminated?
- Is the road used by public transport vehicles or a
significant percentage of heavy goods vehicles?
- Is operation to be one-way or two-way?
8/20/2019 Chapter 7_Traffic Signs, Markings and Signals
28/64
PREPARATION OF THE EAST AFRICAN TRANSPORT FACILITATION STRATEGY
BUREAU FOR INDUSTRIAL COOPERATION Chapter 7 page 28
- Are chicanes to be landscaped?
- Are diagrammatic signs required to assist
awareness?
Raised Intersections
- Is the junction signalized or not?
- Are additional measures necessary to control
pedestrians?- Can the vertical height of the plateau be made
clearly visible to drivers?
From the answers to the questions the need for additional signing can be determined. From the
point of view of traffic signing it is important that the road users be made aware of the measures
and the measures be made visible to the road users at a sufficient distance to allow proper and
safe response.
There is also a need to standardize the design of the physical devices used for traffic calming.
7.7 IMPLEMENTATION PLAN FOR APPROVED CHANGES
The following conditions and approach to the implementation of those recommendations that
shall be approved is suggested:
i. Each member state is to develop and publish its road traffic signs manual and up-dated
highway code based on what was agreed,
ii. Member states be allowed to maintain in their manuals road signs peculiar to their own
country’s usage and most appropriate language provided that such signs shall notconstitute violation of the adopted uniform schedules,
iii. The new manual be followed in all new and rehabilitation projects and in the course of
maintenance of road signs and markings,
iv. The new manual be followed as soon as practicable for all regional routes,
v. Areas recognized and preserved as historical/heritage sites be exempt from all proposed
changes (e.g. Mji Mkogwe – Zanzibar), and
vi. Each member state is to ensure that training of drivers is done using the approved road
signs schedule and an effective awareness campaign to inform road users regarding the
changes is effectively implemented.
This plan is appropriate considering that most of the changes proposed are to enhance the
visibility of signs on roads with higher design standards and expansion of the signs schedules.
