markers used in or on roads, road related areas and other places including kerbs, for the purpose of regulating, guiding and warning road users, and provides guidelines for appropriate use. 2.0 Legal Requirements An "Instrument of General Approval" has been issued by the Minister for Transport to Councils and the Commissioner of Highways (and some other authorities) to use traffic control 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 of Technical Requirements for the Legal Use of Traffic Control Devices (The Code) which forms part of ‘The Legal and technical responsibilities for Traffic Control Devices’. One of the conditions of general approval is the requirement that the design, installation, alteration and removal of pavement markings be in accordance with the Code. This manual has been developed to conform with the Code and takes into consideration the relevant Australian Road Rules, Australian Standards, Austroads guidelines and Department of Planning Transport and Infrastructure Operational Instructions. Pavement markings not conforming to this Manual and the Code, such as innovative or nonstandard treatments are not authorised to be used under the Instrument of General Approval issued by the Minister. Authorisation for such treatments may only be given by the Manager, Traffic and Access Standards Section, Department of Planning Transport and Infrastructure (DPTI), 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 for the proper regulations, warning and guidance of drivers, cyclists, pedestrians and other road users. Pavement Markings may guide traffic or give advance warning or may impose restrictions which are supported by the Road Traffic Act. They may act as a supplement to other traffic control devices or may be used alone to convey certain regulations, warnings and guidance. It is therefore important to ensure that the use of the markings conforms with the legal requirement mentioned above before they are approved, installed, altered or removed to avoid possible conflict or confusion, legal or otherwise. 3.2 Removal of Markings Where traffic conditions are altered and the existing pavement markings no longer apply it is essential that those markings be removed or obliterated. It is important that the end result of removing markings does not leave an impression of the marking on the road surface which may otherwise be interpreted as a marking in certain light and/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. Pavement Marking Manual A-1 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 an edge 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 of conveying 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, raised pavement 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. Yellow shall be used on pavement bars and to define tram only lanes and areas where parking/stopping restrictions apply. Blue is used for disability access. Raised pavement markers may be white, red or yellow. Black paint may be used in the gaps and around the edges of pavement markings to heighten contrast where a light coloured pavement does not allow adequate marking definition to be obtained. Where this is being considered advice should first be sought from Manager, Traffic and Access Standards Section, DPTI. In situations such as community events on closed roads light blue coloured pavement markings (known as honour lines) may be used to define pedestrian boundaries. These markings are not considered traffic control devices but should be removed after the 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 highlight the road surface in a visual, tactile or audible manner. Such treatments may supplement traffic control devices (e.g. bus lanes, bicycle lanes and islands) or they may be aesthetic devices to supplement streetscape designs (e.g. intersection threshold paving treatments). For commonly used distinctive coloured pavement areas used in South Australia, refer to Part A 2.15. 3.9 Off Street Parking Areas AS 2890.1 and AS 2890.6 are used in South Australia for off street car parking pavement markings. A-2 Pavement Marking Manual Types of Markings PART B Types of Markings B 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 the manual. Do not scale off drawings. 1.b Installation Specifications DPTI shall and all other road authorities should require pavement marking to be installed in accordance with DPTI Master Specification for Road Works parts: 245 Supply of Materials for Pavement Markings 246 Application of Pavement Marking 247 Application of Audio Tactile Line Marking Pavement Marking Manual B-1 Types of Markings 2.0 TYPES OF MARKINGS 2.1 LONGITUDINAL LINES Line width Colour (mm) 2.1.1 Dividing lines (separates opposing traffic flows only) 3m ▼ ▼ ▼ ▼ ▼ ▼ ▼ 9m ▼ 3m ▼ 9m ▼ 3m ▼ 9m ▼ 3m ▼ ▼ (a) Single broken (standard) width Colour (mm) ▼ ▼ W 200 W 100 W 200 W 100 100 100 W 100 100 100 W ▼ 9m ▼ ▼ 3m ▼ ▼ ▼ 9m 100 ▼ (b) Enhanced broken (multi-lane) ▼ 2.1.2 Barrier dividing lines (separates opposing traffic flows only) t (a) Single continuous barrier t t (b) Enhanced single continuous barrier 3m t t t t t t t t 9m t 3m t 9m t 3m t t t 9m t 3m t (c) Double one-way barrier t t (d) Double two-way barrier t Where the road speed limit is <70 km/h and : - Double two-way barrier lines are justified then a single continuous barrier line shall be used, including approaches to railway crossings and ferries.

Dimensions shall be clearly shown to either the leading or trailing face of all transverse lines, except pedestrian cross walk lines. Pedestrian crosswalk lines shall be dimensioned to the centre of the line. 3.3 PARKING CONTROL LINES 3.3.1 Parking Control Edgelines All parking control lines (where used) shall be shown on traffic control drawings. Parking control edge lines shall be marked in a consistent alignment parallel to and approximately 400mm from the kerb or edge of seal. 3.3.2 Parking Space Outlines Parking space outlines shall be shown and dimensioned on traffic control drawings. 3.4 DIAGONAL STRIPES AND CHEVRON MARKINGS Diagonal stripes and chevron marking shall be shown on traffic control drawings. 3.5 ARROWS All arrows shall be shown on traffic control drawings and may be dimensioned longitudinally. Arrows shall be located centrally within the lane width as shown in Part B 2.5. 3.6 MESSAGES AND SYMBOLS All messages and symbols shall be shown and the longitudinal spacing dimensioned longitudinally on traffic control drawings. Messages and symbols shall be located centrally within the lane such that a minimum of 150mm gap is maintained between the edge of the message or symbol and the centre of any adjacent longitudinal line or to the edge of seal. Spacing between letters to form commonly used words are shown in Part B 2.6.2. Bicycle symbols shall be located approximately 100mm from the bicycle lane line adjacent to the traffic lane. Where the bicycle lane is less than 1.4 metres wide it will be necessary to reduce the width of the symbol. This will be achieved by masking part of the rear wheel to preserve the 100mm gap between the edge of the symbol and the centre of lane line. Symbols on paths shall be located centrally within the designated area of travel i.e. between the left edge of the path and the separation line. Examples for both symbols and messages on paths is shown in Part C 2.19. B-42 Pavement Marking Manual Design Guide PART C Design Guide 1.0 Scope C This section describes the requirements for the correct and consistent use of pavement markings 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 : l The Road Traffic Act l Australian Road Rules (ARR) l The Technical Requirements for the Legal Use of Traffic Control Devices (The Code) l Australian Standards (AS) l Austroads Guide to Traffic Management (GTM) l Austroads Guide to Road Design (GRD) l Department for Transport, Energy and Infrastructure (DTEI) l Operational Instructions (OI) All road authorities including their consultants and contractors are required to conform to this manual. NOTE: Dimensioning Convention All drawings are not to scale. The reader shall use the dimensions specified throughout the manual. Do not scale off drawings. All markings (longitudinal and transverse) are dimensioned centre to centre, except for Give Way, Stop lines and pavement messages. lane lines x Give Way, Stop lines and pavement messages are generally measured from either the leading or trailing edge of the line or message. crosswalk line y trailing edge stop line leading edge Pavement Marking Manual C-1 Design Guide 2.0 GENERAL TREATMENTS References 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 South Australia. It is important for designers to remember that the use of single continuous dividing line prohibits certain crossing movements, including U turns, but does not prohibit entering or leaving the road. U turns should generally not be restricted by the use a single continuous lines unless site distance is poor or special facilities have been provided to satisfy U turn demand within the section of road. ARR 132, 134 AS1742.2 Section 5 GTM Part 10 OI 2.15 OI 2.27 OI 2.40 Any assessment for the need for dividing lines should take the following into consideration: l All ‘arterial’ roads shall be provided with dividing lines in urban areas, and shall be augmented with RRPM’s. l All ‘collector’ roads should be provided with dividing lines. l Local roads may be provided with dividing lines. Installing dividing lines on narrow roads may have implications for parking. l Where provided between major intersections dividing lines should be broken, and shall be standard width for two lane roads and enhanced for multi lane roads. l Where provided on minor or local roads at intersections, short sections of continuous dividing lines may be provided (see intersection examples in Part B 2.13.8, 2.13.9 and Part C 3.7). l Double barrier lines, i.e. multiple lines consisting of combinations of broken and continuous lines or double continuous lines, are not used on urban roads. l Broken dividing lines on arterial roads continue through minor road intersections. l 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. However there 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 through movements are prevented or prohibited from the minor road. Dividing lines should always be provided on minor road approaches that have give way or stop lines (also see Part C 2.12).

A single continuous barrier line should be used where the speed limit is <70km/h or as an alternative to permit traffic to cross the line to enter or leave the road. Where single continuous barrier line is used, it shall be standard width on roads <70km/h and enhanced on roads >80km/h. ARR 132, 134 AS1742.2 Section 5 AS1742.7 Section 3 GTM Part 10 OI 2.15 OI 2.40 OI 7.1 Generally single continuous lines should be used instead of double barrier lines (one-way or two- 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) to control vehicle movements. However experience has shown that such treatments are generally too passive in nature. Where it is considered necessary to prohibit all crossing movements (for road safety) then preference should be given to physical controls e.g. raised medians and islands, that are self regulating and do not rely on police enforcement to be effective. For further information on the use of barrier lines on rural roads refer to Part C 3.4. Pavement Marking Manual C-3 Design Guide 2.3 DIAGONAL STRIPES AND CHEVRON MARKINGS References Diagonal stripes and chevron markings are used to augment and highlight pavement marking treatments. They often have legal significance under the ARR. They take the form of chevrons when used to indicate that drivers, travelling in the same direction may pass either side of the treated area or as diagonal stripes where the treatments separate opposing traffic flows. Refer to Part B 2.4 for detailed layout of stripes. ARR 88, 138 and 197 AS1742.2 Section 5 GRD Part 4A Spacing between diagonal stripes at low speed turns is generally 6m. The spacing for diagonal 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 or curved and shall be at 45 degrees to the centre line of the divergence where drivers travel on both sides of the markings. While not exclusive, below are examples of diagonal treatments. Traffic on either side (opposing direction) Traffic to right side only bo ker ge r ed eal of s Indicates direction of travel Traffic on either side (same direction) C-4 Pavement Marking Manual Design Guide 2.3.1 Corner Treatment References On curved alignments, where diagonal markings are not parallel, the spacing of the markings shall be measured at the outline or edgeline. C 45 o 6m* 45 o Indicates direction of travel kerb or edge of seal The use of diagonal stripes is discouraged on left turn treatments, where the left turn driver has priority. Stripes are a passive treatment and in this location are usually driven over regulary, requiring additional maintenance. They can also be a slip hazard with differential skid resistance between the painted area and the pavement. kerb *Nominal spacing between stripes is 6 metres but may be varied. For rural treatments the spacing may be increased depending on the radius of the curve. Where the section to be striped is short it is preferable to provide stripes closer together (as close as 3 metres) to ensure the stripes provide the desired effect of discouraging traffic from driving on the area. Pavement Marking Manual C-5 Design Guide 2.3.2 Flush medians References Flush medians may separate lanes dividing opposing traffic streams, while allowing access to and from the road or entrance to a turning lane. ARR 138 It should be noted that unlike raised medians, flush medians do not provide physical control of traffic movements nor do they have the advantages of being clearly visible, especially at night and in wet weather. Spacing between median breaks *12m Diagonal marking variations for median breaks widest point taper point 30m *15m widest point >10 but <20 *15m widest point widest point <10m widest point Indicates direction of travel * 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. C-6 Pavement Marking Manual Design Guide References 2.3.3 Corner islands The use of very small corner islands (less than 3m sides) should be avoided. Such islands cause 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 raised island where better turning control is required. However they should only be augmented with diagonal stripes where the distance between the kerb and outline is greater than 1.0m. C Flush Corner Island >3m - <12m <3m <3m >3m - <12m 1m 1m Corner Islands both flush and raised for left turning vehicles should be augmented with chevron markings for the guidance of both left turn and through vehicles.

C-8 Pavement Marking Manual Design Guide References 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 parking areas and at the start of median sections. C It is preferable to provide as long a divergence length as possible, especially where two or more adjacent lanes must diverge. The following diverge calculation provides a minimum length. However, experience has shown that greater lengths should be provided whenever possible. For example, extra taper length is important for pedestrian refuge situations to provide additional protection for pedestrians and to avoid constant damage to signs and pedestrians hand rails.

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 areas and should be provided in rural areas. RRPMs should also be provided on lane lines, special purpose lane lines and flush island outlines. RRPMs enhance longitudinal lines to such an extent that they discourage crossing movements. For this reason RRPMs shall not be used on continuity lines except in circumstances shown. RRPMs may be used on collector and local roads if additional delineation treatment is considered necessary. For the use of non-reflective pavement markers through intersections, refer to Part C 2.17.6. C-10 Pavement Marking Manual Design Guide 2.5.1.Continuity lines References Generally RRPMs are not required on continuity lines. However, in some rare cases they may be 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. C 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. 12m where RRPMs on continuity lines are used, it must be shown / indicated on the design drawings. 2.5.2 Bicycle lanes The provision of RRPMs can be hazardous to cyclist’s when placed adjacent bicycle lane lines. This is particularly the case for part-time bicycle lanes when cyclist’s are required to ride around parked cars outside bicycle lane operating times. Therefore it is recommended that RRPMs not be located adjacent to or near part-time bicycle lane lines. It may also be appropriate to not install RRPMs on full-time bicycle lanes in areas where cyclists are required to ride around buses and other vehicles legitimately stopped on the road. Pavement Marking Manual C-11 Design Guide 2.6 LANE LINES References Lane lines divide two or more lines of traffic travelling in the same direction and shall be provided on roads where traffic is expected to travel in more than one lane. ARR 146 AS1742.2 Section 5 Lanes in urban areas should not be marked on a road where it would result in lane widths of less than 3.0m. Where kerbside lanes are designed to be shared with cyclists, the minimum lane width shall be 3.7m Lane lines are normally standard broken. However, continuous lane lines may be required between exclusive through and exclusive turn lanes on approaches to intersections (see Part C 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 is shown in the table in Part C 2.4.2. For lane lines on the approach to signalised intersections see Part C 2.17.5.

The lane lines within the circulating lanes and leading out of a roundabout, known as special purpose lines, provide added guidance through the curves while negotiating within and exiting the roundabout. Lane lines must be curved where necessary to ensure this guidance is further enhanced. ARR Part 9 AS1742.2 Section 5 GTM Part 6 GTM Part 10 C Exit line placement additional two exit lines should be provided after the exit. where drivers in the left lane wishing to continue in the circulating path around the roundabout they are required to cross the exit line, it is preferable that the exit line extend from a point within the circulating path and continue into the exit road. exit area starting position for exit line, see inset for each exit line around the roundabout.

They are used 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 they may continue to have the same legal effect in regard to traffic movements. Examples of continuity lines include : l To provide continuity at very wide straight openings across side roads or other entry and exit points along a road or across those openings that are subject to significant vertical or horizontal changes. Continuity lines should only be provided for such situations where it is likely that through traffic would otherwise loose continuity of travel (see Part C 2.5.1 for example). l At the start and end of auxiliary and special purpose lanes to indicate the section of road that should be crossed to access or exit the auxiliary lane. l Across side roads and other sections of road to indicate the continuance of bicycle lanes. l Across median openings where the median is greater than 2 metres in width. 2.7.1 Left and right turn storage / deceleration lanes A kerb or edge of bitumen x Indicates direction of travel 2.7.2 Left and right turn acceleration lanes A kerb or edge of bitumen A <72m x x 0m (all continuity line) 72m - 120m 12m continuity line 120m - 180m 24m continuity line >180m 36m continuity line NOTE: A single continuous line has regulatory importance in the ARRs.

Generally parking control markings, such as lines, T’s and L’s used to delineate parking spaces are white. Clearways, both part time and full time shall not be marked with edgelines. Full time parking restriction lines i.e. unbroken yellow lines, may be used to designate No Stopping areas (with or without sign posting), but shall not be used to designate No Stopping areas already covered in the Road Rules i.e. driveways, corners of road intersections, bus stops, post boxes and fire hydrants. If yellow parking control lines are used along a section of road, they shall not be marked through bus stops. The lines shall also not be marked 3m each side of a post box or 1m each side of a fire hydrant, or through designated taxi zones (taxi zones must be sign posted and may be delineated with parking space markings). 2.11 PAVEMENT MESSAGES (Including Symbols) Pavement messages on roads shall be limited to the following : l BUS LANE l BUS LANE AHEAD l BUS ONLY AHEAD l FERRY l GIVE WAY l KEEP CLEAR l LEFT TURN ONLY l NO LEFT TURN l NO RIGHT TURN l PED XING l RAIL X (X RAIL) l RIGHT TURN ONLY l SCHOOL l SIGNALS AHEAD l STOP l Bicycle (symbol) l Pavement Arrows l Yellow Box Markings l BUS ONLY Pavement messages for other road related areas shall be limited to the following: l Bicycle (symbol) l Bicycle Prohibited (symbol) l Access (symbol) l Path Arrows l Pedestrian (symbol) l Skater Prohibited (symbol) C-22 Pavement Marking Manual Design Guide 2.11.1 Keep clear References The keep clear pavement message shall only be used in accordance with Operational Instruction 2.23 KEEP CLEAR Pavement Markings Keep clear pavement markings shall consist of the words “KEEP CLEAR” and : l Be positioned wholly within a single lane where possible. l Shall have 2.5m letter height with 2.5m spacing between words. l Shall have a letter style as shown in AS1742.2. l Where two or more lanes are to be marked with KEEP CLEAR, the message may be staggered at wide side roads or driveways.

They also provide traffic calming qualities to a road by removing parking from the through traffic. As the name suggests, kerb extensions should preferably consist of raised areas bordered by semi mountable median type kerbing. However, they may also consist of pavement markings designated by outline markings with diagonal stripes, and pavement bars and/or RRPMs. Kerb extensions may also be used to physically control the movement of vehicles, such as a traffic divergence on a road section or to create a high angle entry to the main road. taper length determined in accordance with Part C 2.4 raised kerb or edge of seal Note: Diagonal stripes should be placed at 6m spacing on the divergence taper section and then at 12m spacing for long parallel sections up to 200m.

The controlled road approaches i.e. the road under Give Way or Stop sign control must be provided with a give way or stop line. The provision of a dividing line from the give way or stop line is preferred. The dividing line would not normally extend beyond 10m from the kerb alignment of the intersecting road. This length of line matches the road rule which prohibits stopping within 10m of an intersecting road.

They shall always be used within an intersection where there is more than one turning lane for turns in a particular direction. They are not required when the path to be followed is obvious to drivers under all conditions. AS1742.14 Where opposing right-turn movements operate in the same phase, care must be taken with positioning 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. It is 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 is necessary to select the design vehicles for the turns, e.g. car and semi-trailer from both directions. Turn lines should not be carried through pedestrian crosswalks but may continue after to continue guidance. Turn lines location shall be determined using design turning envelope as a guide, however each location will be different depending on, for example, approach road angles, number of turn lanes and/or phase sequence.

They should only be used in lanes from which the movements differ from the road rules. e.g. The road rules allow drivers to turn left or travel through an intersection from the left lane. If these movements are to be permitted 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 which arrows shall be provided. C Intersection pavement arrows shall not be used to indicate a turn where the turn is restricted during certain hours of the day. When used, a minimum of 3 arrows should be provided in a traffic lane on the approach to traffic signals. The arrow closest to the intersection shall be provided 6m from the stop line or from the tangent point of the curve for a left turn lane. Subsequent arrows should normally be provided at as close to 30m spacing as possible (tail to tail). However, to ensure three arrows are provided, spacing may be reduced down to a minimum of 15m.

On the approach lane lines should cease with a full line segment at the stop line. This may require a shorter gap segment, or a longer line segment. C On exits to intersections where pedestrian crosswalks exist, lane lines should start as close 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.

The distinctive features including the legal effect for some of these facilities is created by the pavement markings. These facilities are known as: Pedestrian refuge Emu crossing Koala crossing Wombat crossing Pedestrian actuated crossing AS1742.10 2.20.1 Pedestrian refuge l Refuges shall be outlined and the outline shall continue past the pedestrian opening. l Where pedestrian openings are provided through medians, outlines shall also continue past the opening but only if that length of median is provided with an outline. l 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 sole purpose of providing a staging area for pedestrians crossing the road or are long lengths of median through which ‘cut outs’ or ‘walkthroughs’ may be provided. refer to Part C 2.4.1 for minimum diverge length and continuous barrier line.

It is placed in advance of a School Zone sign, subject to site conditions. ARR 23 The Code 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 the marking commencing 30m in advance of the sign. C ‘SCHOOL’ pavement messages may be used where visibility to the school zone (zigzag markings) is limited. These markings supplement School Zone warning sign(s). Other markings, such as speed limits, coloured patches or symbols shall not be used.

When water is over the roadways delineation is reduced because the edgelines and particularly the standard dividing line (3m line, 9m gap) is very difficult to see through the water. However, it is important not to unreasonably restrict traffic movement by providing an continuous dividing line. C 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 the section of road regularly subject to flooding.

In cases other than those listed below, treatments should be 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 relate to undivided roads, the same principles, with the exception of dividing lines, should be applied for divided roads. 3.2 MULTI-LANE UNDIVIDED RURAL ROADS Multi-lane undivided roads shall not be used in high speed rural environments with the exception of specific treatments such as overtaking lanes, CHR and CHL intersection treatments. 3.3 DIVIDING LINES ON RURAL ROADS Dividing lines shall be installed in accordance with AS1742.2 other than at isolated intersections treatments. The use of single continuous barrier lines as dividing lines are not recommended in high speed rural environments. Although such lines prohibit certain crossing movements, including u-turns, they do not prohibit entering or leaving the road (see Barrier Lines on Rural Roads). AS1742.2 Section 5 Any assessment for the need for dividing lines needs to consider the following: l All rural ‘arterial’ roads shall be provided with dividing lines and should be augmented with RRPM’s. l All rural ‘collector’ roads should be provided with dividing lines. l Local rural roads may be provided with dividing lines. Installing dividing lines on narrow roads may have implications for parking. l Where provided between major rural intersections dividing lines should be broken, and shall be standard width for 2 lane roads and enhanced for multi lane roads. l Where provided on minor or local rural roads at intersections, short sections of single continuous barrier line may be provided. l 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 to double two-way barrier lines. This allows the line to be crossed by traffic entering or leaving the road. Barrier lines on high speed rural roads shall only consist of double lines, either ‘Double One Way Barriers’ or ‘Double Two Way Barriers’ to create ‘No Overtaking Zones’ and shall be restricted to locations with either horizontal or vertical sight restrictions or both and only be determined in accordance with AS1742.2. Double barrier lines, one way or two way, are not generally used in SA to prohibit overtaking at isolated locations unless there are sight restrictions which meet requirements for such lines. The only exceptions to the above requirement include: l l l Railway level crossings in accordance with Australian Standards Manual of Uniform Traffic Control 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. C-66 AS1742.7 Section 3 OI 2.15 Pavement Marking Manual Design Guide 3.5 LANE LINES ON RURAL ROADS References Lane lines i.e. lines dividing lanes of the same direction traffic, must be provided on roads where 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 than 3.2 metres. Restricted access routes may require greater lane widths. C Lane lines are normally standard broken. However, unbroken lane lines may be used between 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 enhanced edgeline sealed shoulder or breakdown lane (unkerbed) dividing strip (kerbed) 175mm sealed shoulder or breakdown lane enhanced edgeline enhanced outline 3.6 EDGELINES ON RURAL ROADS Edgelines are provided on most rural arterial roads. They provide a clear definition of the lane and discourage traffic from travelling on shoulders. AS1742.2 Section 4 AS1742.2 Section 5 GRD Part 3 They are particularly effective at night. Edgelines shall be provided on all rural roads to ensure the desirable alne width does not exceed 3.5 metres. Practices regarding lane and sealed shoulder widths including the issues relating to pavement 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 and edgelines. Part C 3.6.3 and 3.6.4 indicates a required treatment.
