Pavement Marking Manual

INTRODUCTIONThis manual specifies the lines, patterns, symbols, letters andnumerals, pavement bars and markers used in or on roads, roadrelated areas and other places including kerbs, for the purpose ofregulating, guiding and warning road users, and provides guidelinesfor appropriate use.

TYPES OF MARKINGSThis Section describes the types of markings including paintsubstitutes, pavement bars, raised pavement markers and colouredand/or textured surfaces.

It details the actual dimensions and other specification attributes ofmarkings which need not be shown on traffic control and road designdrawings.

DESIGN GUIDEThis section describes the requirements for the correct and consistentuse of pavement markings in South Australia.

It is intended that the section provide specific diagrammatic examplesof the application of markings and where necessary explain to thedesigner the reasons why certain treatments are used. It alsoprovides references to the Code of Technical Requirements for theLegal Use of Traffic Control Device (The Code), Australian Standards,Austroads and Department for Transport Energy and Infrastucture(DTEI) Operational Instructions.

Pavement Marking Manual A-1

Introduction

APART AIntroduction

1.0 Scope

This manual specifies the lines, patterns, symbols, letters and numerals, pavement bars andmarkers used in or on roads, road related areas and other places including kerbs, for thepurpose of regulating, guiding and warning road users, and provides guidelines forappropriate use.

2.0 Legal Requirements

An "Instrument of General Approval" has been issued by the Minister for Transport toCouncils and the Commissioner of Highways (and some other authorities) to use trafficcontrol devices which includes pavement markings. The conditions of this general approval,which are required by law under the Road Traffic Act are contained in Part 2 - Code ofTechnical Requirements for the Legal Use of Traffic Control Devices (The Code) which formspart of ‘The Legal and technical responsibilities for Traffic Control Devices’. One of theconditions of general approval is the requirement that the design, installation, alteration andremoval of pavement markings be in accordance with the Code.

This manual has been developed to conform with the Code and takes into consideration therelevant Australian Road Rules, Australian Standards, Austroads guidelines and Departmentfor Transport Energy and Infrastructure Operational Instructions.

Pavement markings not conforming to this Manual and the Code, such as innovative or non-standard treatments are not authorised to be used under the Instrument of General Approvalissued by the Minister. Authorisation for such treatments may only be given by the Manager,Traffic and Access Standards Section, Department for Transport Energy and Infrastructure(DTEI), acting as the Minister’s delegate.

3.0 General Attributes

3.1 Purpose

A system of clear, effective and consistently applied pavement markings is essential forthe proper regulations, warning and guidance of drivers, cyclists, pedestrians and otherroad users.

Pavement Markings may guide traffic or give advance warning or may imposerestrictions which are supported by the Road Traffic Act. They may act as asupplement to other traffic control devices or may be used alone to convey certainregulations, warnings and guidance.

It is therefore important to ensure that the use of the markings conforms with the legalrequirement mentioned above before they are approved, installed, altered or removedto avoid possible conflict or confusion, legal or otherwise.

3.2 Removal of Markings

Where traffic conditions are altered and the existing pavement markings no longerapply it is essential that those markings be removed or obliterated. It is important thatthe end result of removing markings does not leave an impression of the marking onthe road surface which may otherwise be interpreted as a marking in certain lightand/or weather conditions.

In rare cases, redundant pavement markings may be allowed to fade but only when these markings cannot be misinterpreted or otherwise create a confusing message to the road user which may create a safety hazard.

Page 10: Http Www.dpti.Sa

Pavement Marking ManualA-2

Introduction

3.3 Limitations

Pavement markings have the following limitations:

(a) They may not be clearly visible if the road is wet or dusty, for example near anedge of a median.

(b) They are subject to traffic wear and usually require frequent maintenance.(c) They can be obscured by traffic.(d) Their effect on skid resistance requires careful choice of materials and precludes

the use of large marked surface areas.(e) They cannot be applied to unsealed roads.

In spite of these limitations they have the advantage under favourable conditions ofconveying information to the driver without diverting attention from the road.

3.4 Reflectorisation

All longitudinal lines except zig zag markings shall be reflectorised.

3.5 Anti-Skid Treatment

An anti-skid treatment shall be applied to all markings other than longitudinal lines.

3.6 Materials

Road pavements may be marked with paint, thermoplastics, pre-cut sheeting, raisedpavement markers (retro-reflective, non reflective or illuminated) or pavement bars.

3.7 Colours

For all traffic control purposes pavement markings shall be white, yellow or blue. Yellowshall be used on pavement bars and to define tram only lanes and areas whereparking/stopping restrictions apply. Blue is used for disability access. Raised pavementmarkers may be white, red or yellow.

Black paint may be used in the gaps and around the edges of pavement markings toheighten contrast where a light coloured pavement does not allow adequate markingdefinition to be obtained. Where this is being considered advice should first be soughtfrom Manager, Traffic and Access Standards Section, DTEI.

In situations such as community events on closed roads light blue coloured pavementmarkings (known as honour lines) may be used to define pedestrian boundaries.These markings are not considered traffic control devices but should be removed afterthe event, to ensure road users are not confused by the markings.

3.8 Distinctive Pavement Colours

There is a trend by road authorities to use distinctive coloured pavements to highlightthe road surface in a visual, tactile or audible manner. Such treatments maysupplement traffic control devices (e.g. bus lanes, bicycle lanes and islands) or theymay be aesthetic devices to supplement streetscape designs (e.g. intersectionthreshold paving treatments). For commonly used distinctive coloured pavement areasused in South Australia, refer to Part 2.15.

3.9 Off Street Parking Areas

AS 2890.1 and AS 2890.6 are used in South Australia for off street car parkingpavement markings.

PART BTypes of Markings

1.a Scope

This Section describes the types of marking used including paint substitutes, pavement bars,raised pavement markers and coloured areas.

It details the actual dimensions and other specification attributes of markings which need not be shown on traffic control and road design drawings.

IMPORTANT :

All drawings are not to scale. The reader shall use the dimensions specified throughout themanual. Do not scale off drawings.

1.b Installation Specifications

DTEI shall and all other road authorities should require pavement marking to be installed in accordance with DTEI Master Specification for Road Works parts:

Gaps should not generally be provided in double two way barrier lines. Leaving a gap allows a driver to legally enterand leave the road as well as U-turns at a place where there may be a restricted sight distance due to horizontal orvertical curves. A gap may only be provided where a survey determines that sufficient sight distance is available tosafely allow all movements.

Where provided the gap shall generally be 5m. The gap may be increased at wider accesses or where the turningvehicle envelope would otherwise cross the double two way barrier lines.

All messages and symbols shall be shown and the longitudinal spacing dimensionedlongitudinally on traffic control drawings.

Messages and symbols shall be located centrally within the lane such that a minimum of150mm gap is maintained between the edge of the message or symbol and the centre of anyadjacent longitudinal line or to the edge of seal. Spacing between letters to form commonlyused words are shown in Part B 2.6.2.

Bicycle symbols shall be located approximately 100mm from the bicycle lane line adjacent tothe traffic lane. Where the bicycle lane is less than 1.4 metres wide it will be necessary toreduce the width of the symbol.

1.0 Scope

This section describes the requirements for the correct and consistent use of pavementmarkings on roads in South Australia

It is intended that the section provide specific diagrammatic examples (i.e. not to scale or proportion) of the application of markings and where necessary explain to the designer the reasons why certain treatments are used. It also provides references to : The Road Traffic Act Australian Road Rules (ARR) The Technical Requirements for the Legal Use of Traffic Control Devices (The Code) Australian Standards (AS) Austroads Guide to Traffic Management (GTM) Austroads Guide to Road Design (GRD) Department for Transport, Energy and Infrastructure (DTEI) Operational Instructions (OI)

All road authorities including their consultants and contractors are required to conform to this manual.

NOTE:Dimensioning Convention

Give Way, Stop lines and pavement messages are generally measuredfrom either the leading or trailing edge of the line or message.

2.0 GENERAL TREATMENTS

General treatments are considered those that apply in all urban built up areas. These include local residential roads, collector roads, arterial roads and expressway type roads in or near cities and townships. They may include roads of any speed environment.

2.1 DIVIDING LINES

There is no traffic volume warrant for the provision of dividing lines on urban roads in SouthAustralia. It is important for designers to remember that the use of single continuous dividingline prohibits certain crossing movements, including U turns, but does not prohibit entering orleaving the road. U turns should generally not be restricted by the use a single continuous linesunless site distance is poor or special facilities have been provided to satisfy U turn demandwithin the section of road.

Any assessment for the need for dividing lines should take the following into consideration:

All ‘arterial’ roads shall be provided with dividing lines in urban areas, and shall beaugmented with RRPM’s.

All ‘collector’ roads should be provided with dividing lines.

Local roads may be provided with dividing lines. Installing dividing lines on narrow roadsmay have implications for parking.

Where provided between major intersections dividing lines should be broken, and shall bestandard width for two lane roads and enhanced for multi lane roads.

Where provided on minor or local roads at intersections, short sections of continuousdividing lines may be provided (see intersection examples in Part B 2.13.8, 2.13.9 and PartC 3.7).

Double barrier lines, i.e. multiple lines consisting of combinations of broken and continuouslines or double continuous lines, are not used on urban roads.

Broken dividing lines on arterial roads continue through minor road intersections.

On any road, a break is provided in continuous dividing lines through intersections (see Part B 2.13.9 for example).

Dividing lines are not normally necessary on minor road approaches to major roads. Howeverthere may be situations where such lines could provide additional guidance to road users.Such cases include :

- Wide side roads- Multi lane side roads- High volumes of right turn movements into and/or from minor road

Dividing lines should not be provided on minor road approaches where right turn and throughmovements are prevented or prohibited from the minor road.

Dividing lines should always be provided on minor road approaches that have give way or stoplines (also see Part C 2.12).

2.2 BARRIER LINES

Double one way barrier lines are used at Railway Crossings and Ferries in both rural andurban areas where the speed limit is >80km/h to prohibit overtaking on the approached side.A single continuous barrier line should be used where the speed limit is <70km/h or as analternative to permit traffic to cross the line to enter or leave the road. Where singlecontinuous barrier line is used, it shall be standard width on roads <70km/h and enhancedon roads >80km/h.

Generally single continuous lines should be used instead of double barrier lines (one-way ortwo- way) in urban and low speed rural areas (also see Part B 2.1.2).

There is a temptation to use double barrier lines (double one-way or double two-way) tocontrol vehicle movements. However experience has shown that such treatments aregenerally too passive in nature. Where it is considered necessary to prohibit all crossingmovements (for road safety) then preference should be given to physical controls e.g. raisedmedians and islands, that are self regulating and do not rely on police enforcement to beeffective.

For further information on the use of barrier lines on rural roads refer to Part C 3.4.

2.3 DIAGONAL STRIPES AND CHEVRON MARKINGS

Diagonal stripes and chevron markings are used to augment and highlight pavementmarking treatments. They often have legal significance under the ARR. They take the formof chevrons when used to indicate that drivers, travelling in the same direction may passeither side of the treated area or as diagonal stripes where the treatments separateopposing traffic flows. Refer to Part B 2.4 for detailed layout of stripes.

Spacing between diagonal stripes at low speed turns is generally 6m. The spacing fordiagonal stripes and chevron markings is generally 6m on roads <70km/h, 12m on roads>80km/h and 24m or 48m on freeways/expressways.

Diagonal stripes shall be placed at 45 degrees to the direction of travel whether straight orcurved and shall be at 45 degrees to the centre line of the divergence where drivers travelon both sides of the markings.

While not exclusive, below are examples of diagonal treatments.

On curved alignments, where diagonal markings are not parallel, the spacing of themarkings shall be measured at the outline or edgeline.

*Nominal spacing between stripes is 6 metres but may be varied. For rural treatments thespacing may be increased depending on the radius of the curve. Where the section to bestriped is short it is preferable to provide stripes closer together (as close as 3 metres) toensure the stripes provide the desired effect of discouraging traffic from driving on the area.

2.3.2 Flush medians

Flush medians may separate lanes dividing opposing traffic streams, while allowing accessto and from the road or entrance to a turning lane.

It should be noted that unlike raised medians, flush medians do not provide physical controlof traffic movements nor do they have the advantages of being clearly visible, especially atnight and in wet weather.

Spacing between median breaks

Diagonal marking variations for median breaks

* Generally spacing between diagonal markings should be 12m. Spacing may be varied between 10 - 15m to suit median lengths. Spacing must be consistent along entire length of each median section. Although it is preferable to provide at least 2 diagonal markings in short lengths, one marking may be used in cases of very short lengths.

2.3.3 Corner islands

The use of very small corner islands (less than 3m sides) should be avoided. Such islandscause confusion to drivers regarding give way responsibilities when turning at intersections.

Chevrons and diagonal stripes may be used between the outline and the kerb of a raisedisland where better turning control is required. However they should only be augmentedwith diagonal stripes where the distance between the kerb and outline is greater than 1.0m.

Flush Corner Island

Corner Islands both flush and raised for left turning vehicles should be augmented withchevron markings for the guidance of both left turn and through vehicles. The treatmentalso clearly define the differences in the ARR between turning movement priorities atintersections.

2.4 DIVERGE AND MERGE TAPER TREATMENTS

2.4.1 Diverge taper treatments

It is often necessary to move traffic laterally across a section of road without merging lanes.Examples include divergence of traffic lanes to avoid pedestrian refuges, on street parkingareas and at the start of median sections.

It is preferable to provide as long a divergence length as possible, especially where two ormore adjacent lanes must diverge. The following diverge calculation provides a minimumlength. However, experience has shown that greater lengths should be provided wheneverpossible. For example, extra taper length is important for pedestrian refuge situations toprovide additional protection for pedestrians and to avoid constant damage to signs andpedestrians hand rails.

A length of continuous barrier line should be provided in accordance with the table below onthe approach / exit to merge and diverge tapers.

Td = Diverge lengthV = Design speed or speed limit (km/h)y = Lateral movement (m)s = Rate of lateral movement diverge = 1m/sec

2.4.2 Merge taper treatments (lane drop and acceleration lane situations)

“Zip merge”, is the preferred merge treatment in urban areaswith a speed limit of less than 80km/h.This is a minimummerge taper length. However, experience has shown thatgreater lengths should be provided, to assist driversundertake the zip merge.

Tm = Merge lengthV = Design speed or speed limit *(km/h)y = Lateral movement (m)s = Rate of lateral movement

merge = 0.6m/sec

Zip merges are not to be used on roads with aspeed limit of 80 km/h or greater.

2.5 RAISED PAVEMENT MARKERS

Broken and continuous lines may be augmented with retroreflective raised pavement markers(RRPMs).

Standard spacing is 12m on lit and 24m on unlit roads.

As a minimum on arterial roads, RRPMs shall be provided on all dividing lines in urban areasand should be provided in rural areas. RRPMs should also be provided on lane lines, specialpurpose lane lines and flush island outlines.

RRPMs enhance longitudinal lines to such an extent that they discourage crossingmovements. For this reason RRPMs shall not be used on continuity lines except incircumstances shown.

RRPMs may be used on collector and local roads if additional delineation treatment isconsidered necessary.

For the use of non-reflective pavement markers through intersections, refer to Part C 2.17.6.

References2.5.1.Continuity lines

Generally RRPMs are not required on continuity lines. However, in some rare cases they maybe required to provide guidance .eg

- On tapers where traffic is required to deviate from their path eg. trapped lane situation.- On long lengths of curvilinear continuity lines.

Note: - RRPMs shall not be used on continuity lines in merging situations.- Where used, spacing shall be generally the same as that applied to lane lines i.e. 24m

on unlit roads, 12m on lit roads.

2.5.2 Bicycle lanes

The provision of RRPMs can be hazardous to cyclist’s when placed adjacent bicycle lanelines. This is particularly the case for part-time bicycle lanes when cyclist’s are required to ridearound parked cars outside bicycle lane operating times. Therefore it is recommended thatRRPMs not be located adjacent to or near part-time bicycle lane lines. It may also beappropriate to not install RRPMs on full-time bicycle lanes in areas where cyclists are requiredto ride around buses and other vehicles legitimately stopped on the road.

2.6 LANE LINES

Lane lines divide two or more lines of traffic travelling in the same direction and shall beprovided on roads where traffic is expected to travel in more than one lane.

Lanes in urban areas should not be marked on a road where it would result in lane widths ofless than 3.0m.

Where kerbside lanes are designed to be shared with cyclists, the minimum lane width shallbe 3.7m

Lane lines are normally standard broken. However, continuous lane lines may be requiredbetween exclusive through and exclusive turn lanes on approaches to intersections (see PartC 2.7). They may also be used to restrict lane changing mid-block.

Lane lines should be continued through minor road intersections.

At a lane drop, the lane line should cease before the taper commences. This distance isshown in the table in Part C 2.4.2.

For lane lines on the approach to signalised intersections see Part C 2.17.5.

For the use of continuity lines as lane lines (including the length of continuous line) seePart C 2.7.

2.6.1 Roundabouts

Lane lines on the approach to a multilane roundabout are positioned as they would be forother intersections. The lane lines within the circulating lanes and leading out of aroundabout, known as special purpose lines, provide added guidance through the curveswhile negotiating within and exiting the roundabout. Lane lines must be curved wherenecessary to ensure this guidance is further enhanced.

where drivers in the left lane wishingto continue in the circulating patharound the roundabout they arerequired to cross the exit line, it ispreferable that the exit line extend froma point within the circulating path andcontinue into the exit road.

References2.7 CONTINUITY LINES

Continuity lines generally provide longitudinal ‘continuity’ to traffic along lengths of roadwhere lane lines or other longitudinal lines either cannot or should not be provided. They areused to substitute lane, dividing or edgelines where it is intended that the line be crossed.

Where they are used in lieu of a lane or dividing line it is important to remember that theymay continue to have the same legal effect in regard to traffic movements.

Examples of continuity lines include :

To provide continuity at very wide straight openings across side roads or other entry andexit points along a road or across those openings that are subject to significant vertical orhorizontal changes. Continuity lines should only be provided for such situations where it islikely that through traffic would otherwise loose continuity of travel (see Part C 2.5.1 forexample).

At the start and end of auxiliary and special purpose lanes to indicate the section of roadthat should be crossed to access or exit the auxiliary lane.

Across side roads and other sections of road to indicate the continuance of bicycle lanes.

Across median openings where the median is greater than 2 metres in width.

2.7.1 Left and right turn storage / deceleration lanes

2.7.2 Left and right turn acceleration lanes

NOTE: A single continuous line has regulatory importance in the ARRs. When a single continuous line is used, ARR permits vehicles to cross it to enter or leave the road or when passing a stationary obstruction (including a parked vehicle), but does not permit overtaking or u-turning.

Full time parking restriction lines i.e. unbroken yellow lines, may be used to designate NoStopping areas (with or without sign posting), but shall not be used to designate No Stoppingareas already covered in the Road Rules i.e. driveways, corners of road intersections, busstops, post boxes and fire hydrants.

If yellow parking control lines are used along a section of road, they shall not be markedthrough bus stops. The lines shall also not be marked 3m each side of a post box or 1meach side of a fire hydrant, or through designated taxi zones (taxi zones must be sign postedand may be delineated with parking space markings).

2.12 KERB EXTENSION MARKINGS

Kerb extensions (formerly known as protuberances) are used to reduce road widths,especially in pedestrian crossing locations. They also provide traffic calming qualities to aroad by removing parking from the through traffic.

As the name suggests, kerb extensions should preferably consist of raised areas borderedby semi mountable median type kerbing. However, they may also consist of pavementmarkings designated by outline markings with diagonal stripes, and pavement bars and/orRRPMs.

Kerb extensions may also be used to physically control the movement of vehicles, such as atraffic divergence on a road section or to create a high angle entry to the main road.

Note: Diagonal stripes should be placed at 6m spacing on the divergencetaper section and then at 12m spacing for long parallel sections up to 200m. For sections longer then 200m where diagonal stripesare considered necessary they may be spaced at up to 24m in urbanareas and up to 48m in high speed rural areas.

2.13 STANDARD INTERSECTIONS (Local Roads)

Local or minor roads need not to be line marked. However, where they are, it is preferred toprovide a single dividing line to the extent of the limit of the No Stopping restriction from theintersection (only) on the road with priority.

The controlled road approaches i.e. the road under Give Way or Stop sign control must beprovided with a give way or stop line. The provision of a dividing line from the give way orstop line is preferred.

The dividing line would not normally extend beyond 10m from the kerb alignment of theintersecting road. This length of line matches the road rule which prohibits stopping within10m of an intersecting road.

Single lane

Multi-lane minor road exits, from major roads, where traffic may enter the side road frommore then one lane, lane lines should be provided. In these cases, the lane line shouldcommence 300mm from the prolongation of the main road kerb line. At least three linesegments are preferred.

For multi-lane minor roads approaching a major road, lane lines should cease with a full linesegment at 300mm back from the prolongation of the main road kerb line. Where a stop orgive way line exists, the full line segment should cease.

Where lane use discipline is a problem, pavement arrows should be provided.

2.16 ROUNDABOUTS

Give Way lines

All roundabouts shall be provided with give way lines at the point drivers are expected to‘hold’ to give way before entering the circulating lane(s). To determine the location of thegive way line it is important to consider sight distance to approaching vehicles from the rightwhile ensuring that the holding vehicle is not placed within the turning path of vehiclestravelling within the circulating lane(s), see Part C 2.14.

Special purpose and lane lines

Refer to Part C 2.6.1.

Note: Spiral lane line markings i.e. where additional lanes are created within a roundabout shall not be used in SA without the authorisation of DTEI, Manager Traffic and Access Standards.

Pavement arrows

Pavement arrows, while not used on single lane roundabouts, shall be used on anyapproach to the roundabout which has more then one lane.

Splitter islands

Splitter islands, raised or flush, shall be provided on each approach. A standard singlecontinuous barrier line should be marked on the approach to a splitter island.

Painted kerb and outlines

All roundabouts, splitter islands and kerb extension shall be painted and may be outlined.For semi-mountable central islands and sppitter islands refer to Part B 2.16.2.

The signalised crossing should be at least 2m wide and delineated by two parallel lines.See Part B 2.2.3.

The line nearest the centre of the intersection should be not less then 0.6m (desirably 1m)clear of the cross street kerb line projection.

Crosswalks shall always be on a straight alignment between staged crossing points.

No other lines shall be placed between the crosswalk lines

2.17.3 Turn lines

Turn lines may be used within signalised intersections to indicate the proper course to befollowed by turning vehicles. They shall always be used within an intersection where thereis more than one turning lane for turns in a particular direction. They are not required whenthe path to be followed is obvious to drivers under all conditions.

Where opposing right-turn movements operate in the same phase, care must be taken withpositioning turn lines so that sufficient gap is left between opposing turning traffic.Austroads turning path templates or recognised equivalent should be used for turn lines. Itis suggested that a gap of 1.2 to 2.0m is provided between the turning vehicle envelopes.At major urban intersections with double right-turn lanes from opposite directions, it isnecessary to select the design vehicles for the turns, e.g. car and semi-trailer from bothdirections.

Turn lines should not be carried through pedestrian crosswalks but may continue after tocontinue guidance.

Turn lines location shall be determined using design turning envelope as a guide, howevereach location will be different depending on, for example, approach road angles, number ofturn lanes and/or phase sequence. Where multi-turn lanes exist adequate separation shallbe provided between each adjacent design turning envelope.

Turn lines can be designed and depicted using turn line design strings.

References2.17.4 Pavement arrows

Intersection pavement arrows may be provided in lanes to indicate the direction in which adriver is legally obliged to travel through the intersection. They should only be used in lanesfrom which the movements differ from the road rules. e.g. The road rules allow drivers toturn left or travel through an intersection from the left lane. If these movements are to bepermitted within the intersection, the pavement arrow should not be provided. For simplicity,use of Intersection Pavement Arrows table (page C-38) shows the movements for whicharrows shall be provided.

Intersection pavement arrows shall not be used to indicate a turn where the turn isrestricted during certain hours of the day.

When used, a minimum of 3 arrows should be provided in a traffic lane on the approach totraffic signals. The arrow closest to the intersection shall be provided 6m from the stop lineor from the tangent point of the curve for a left turn lane. Subsequent arrows shouldnormally be provided at as close to 30m spacing as possible (tail to tail). However, toensure three arrows are provided, spacing may be reduced down to a minimum of 15m.The last arrow shall be provided at a point where the full lane width is developed. For veryshort lanes where three arrows cannot be provided (at 15m spacing) the number of arrowsmay be reduced.

References2.17.5 Lane lines

On the immediate approaches to traffic signals, the use of lane lines is essential wherethe approach width will accommodate two or more traffic streams.

On the approach lane lines should cease with a full line segment at the stop line. Thismay require a shorter gap segment, or a longer line segment.

On exits to intersections where pedestrian crosswalks exist, lane lines should start asclose as practicable (but not closer than 300mm) to the crosswalk.

For zip merges on the exit to intersections, refer to Part C 2.4.2.

For the use of continuity lines as lane lines, refer to Part C 2.7.

2.17.6 Non-reflective raised pavement markers

Vehicles my require guidance through intersections by the placement of Non-ReflectiveRaised Pavement Markers (NRPM) within the intersection for non-turning traffic.Treatment is normally applicable only to wide signalized intersections on multilane roads.NRPM must be placed such that they do not interfere with the alignment of the crossmovement lanes.

Typical situations are:

Lanes on opposite sides of the intersection offset by half a lane width or more.

Drivers required to steer a curved course through the intersection.

Highly skewed intersections where the travel distance within the intersection is excessive.

Features such as tram lines or adverse geometry which may make the course difficult to follow.

2.20 PEDESTRIAN TREATMENTS

There are a number of distinctive facilities to assist the safe passage of pedestrians walkingadjacent to and across roads. The distinctive features including the legal effect for some ofthese facilities is created by the pavement markings.

These facilities are known as:Pedestrian refugeEmu crossingKoala crossingWombat crossingPedestrian actuated crossing

2.20.1 Pedestrian refuge

Refuges shall be outlined and the outline shall continue past the pedestrian opening.

Where pedestrian openings are provided through medians, outlines shall also continuepast the opening but only if that length of median is provided with an outline.

Where the pedestrian refuge divides opposing traffic movements unidirectional yellow RRPMs shall be provided at 6.0m spacings. White RRPMs shall be provided at the same spacing where the refuge separates traffic travelling in the same direction.

Pedestrian refuges are either short lengths of raised medians used on roads for the solepurpose of providing a staging area for pedestrians crossing the road or are long lengths ofmedian through which ‘cut outs’ or ‘walkthroughs’ may be provided.

2.21 SCHOOL ZONES

A zigzag marking is used to increase driver awareness of a school zone. It is placed inadvance of a School Zone sign, subject to site conditions.

Zigzag pavement markings shall be used at all School Zones.

Typically the trailing end of the zigzag marking is placed at the school zone sign with themarking commencing 30m in advance of the sign.

‘SCHOOL’ pavement messages may be used where visibility to the school zone (zigzagmarkings) is limited. These markings supplement School Zone warning sign(s).

Other markings, such as speed limits, coloured patches or symbols shall not be used.

The zigzag markings must be as shown in Part B 2.9, unless otherwise indicated in thefollowing examples.

References2.24 FLOODWAYS AND CAUSEWAYS

Floodways and causeways are sections of road that are subject to flooding. When water isover the roadways delineation is reduced because the edgelines and particularly thestandard dividing line (3m line, 9m gap) is very difficult to see through the water. However, itis important not to unreasonably restrict traffic movement by providing an continuous dividingline.

To increase delineation qualities of the dividing line while still allowing the line to be crossed,a special purpose broken dividing line ( i.e. 9m line, 3m gap) shall be used across thesection of road regularly subject to flooding.

3.0 RURAL TREATMENTS

This section details the pavement marking differences between the general or urbantreatments and those in rural areas. In cases other than those listed below, treatments shouldbe the same for both built up urban and rural situations.

3.1 DIVIDED RURAL ROADS

Although most of the design details for treatments between intersections in this section relateto undivided roads, the same principles, with the exception of dividing lines, should be appliedfor divided roads.

3.2 MULTI-LANE UNDIVIDED RURAL ROADS

Multi-lane undivided roads shall not be used in high speed rural environments with theexception of specific treatments such as overtaking lanes, CHR and CHL intersectiontreatments.

3.3 DIVIDING LINES ON RURAL ROADS

Dividing lines shall be installed in accordance with AS1742.2 other than at isolatedintersections treatments. The use of single continuous barrier lines as dividing lines are notrecommended in high speed rural environments. Although such lines prohibit certain crossingmovements, including u-turns, they do not prohibit entering or leaving the road (see BarrierLines on Rural Roads).

Any assessment for the need for dividing lines needs to consider the following:

All rural ‘arterial’ roads shall be provided with dividing lines and should be augmented withRRPM’s.

All rural ‘collector’ roads should be provided with dividing lines.

Local rural roads may be provided with dividing lines. Installing dividing lines on narrowroads may have implications for parking.

Where provided between major rural intersections dividing lines should be broken, andshall be standard width for 2 lane roads and enhanced for multi lane roads.

Where provided on minor or local rural roads at intersections, short sections of singlecontinuous barrier line may be provided.

Dividing lines on rural arterial roads through minor road intersections are generally broken(see Part C 3.8 Standard Rural Intersections).

3.4 BARRIER LINES ON RURAL ROADS

A single continuous barrier line should be used through rural townships as an alternative todouble two-way barrier lines. This allows the line to be crossed by traffic entering or leavingthe road.

Barrier lines on high speed rural roads shall only consist of double lines, either ‘Double OneWay Barriers’ or ‘Double Two Way Barriers’ to create ‘No Overtaking Zones’ and shall berestricted to locations with either horizontal or vertical sight restrictions or both and only bedetermined in accordance with AS1742.2.

Double barrier lines, one way or two way, are not generally used in SA to prohibit overtakingat isolated locations unless there are sight restrictions which meet requirements for suchlines.

The only exceptions to the above requirement include:

Railway level crossings in accordance with Australian Standards Manual of Uniform TrafficControl Devices (AS1742).

Overtaking lanes in accordance with this document and Operational Instruction 2.15 Ferry approaches in accordance with Australian Standards Manual of Uniform Traffic

Control Devices.

3.5 LANE LINES ON RURAL ROADS

Lane lines i.e. lines dividing lanes of the same direction traffic, must be provided on roadswhere traffic is expected to travel in more than one line of traffic.

Lanes should not be marked on a rural road where it would result in lane widths of less than3.2 metres. Restricted access routes may require greater lane widths.

Lane lines are normally standard broken. However, unbroken lane lines may be usedbetween exclusive through and exclusive turn lanes on approaches to intersections.

Lane lines on rural roads should be continued through minor road intersections.

All multi lane divided rural roads shall be provided with enhanced edgelines and outlines.

Multi lane divided rural road

3.6 EDGELINES ON RURAL ROADS

Edgelines are provided on most rural arterial roads. They provide a clear definition of thelane and discourage traffic from travelling on shoulders.

They are particularly effective at night.

Edgelines shall be provided on all rural roads to ensure the desirable alne width does notexceed 3.5 metres.

Practices regarding lane and sealed shoulder widths including the issues relating topavement depth, should be considered before providing an edgeline.

Part C 3.6.1 and 3.6.2 show best practice in regard to installation of dividing lines andedgelines.

Part C 3.6.3 and 3.6.4 indicates a required treatment.
