Published on Oct View 1. Road Marking and Dileanation7. The manual is now divided into the following parts: Standard traffic signs drawings for Regulatory, Warning and Guide signs are illustrated complete with dimensions.

A colour chart for all the traffic signs indicates acceptable colours for each sign. It consists of, with the exception of Temporary signs, design criteria and location requirements for all traffic signs. It consists of standard temporary signs drawings and their application in the work zones. Standard road line paints, road markings and delineators are identified together with guides on their applications.

The specifications in this manual are recommended to be used for new signs and for all replacements of existing signs which have outlived their usefulness. They may be used either alone or to supplement other traffic control devices.

Other markings and delineations required by road conditions or restrictions should be remove or obliterated when those conditions cease to exist or the restrictions are withdrawn.

All markings on highways shall be reflectorised. Even on well lighted town and streets it is generally desirable markings which must be visible at night be reflectorised. They may not be clearly visible arhan wet, and may not be very durable when subjected to heavy traffic. Therefore they require frequent maintenance. Their effect on skid resistance requires care in the choice of materials to be used. Finally they cannot be applied to unsealed roads.

Road jalqn may be marked by one or more of the following materials: Paint is best used in situations and on roads where the markings are not subjected to heavy traffic wear.

S or the equivalence. This material is applied hot and sets on laying. It has good durability and is recommended to be used in heavily travelled urban areas and in main highways with high traffic densities. All road centre lines shall be in thermoplastics. The markings must be patterned or embossed in order secure satisfactory resistance to tkenik. It can be used as temporary markings because it can be removed easily even after an extended time period. Yellow paint may be used at: The standard colour arxhan yellow markings shall be colour No.

The broken line shall consists of strokes of equal length separated by uniform gaps. The speed of vehicles on the section of road or in the area in question should be taken into account in determining the length of the strokes and of the gaps between them.

The standard ratio of gap to stroke of 5 to 3 shall be used. On rural roads use a gap of 7. However, on teknnik terrain or with short radius curves, use a 4. On 4-lane undivided rural roads, the centre line shall consists of two unbroken white lines, each mm wide and separated by a space of mm.

Centre lines shall be provided on all paved 2lane roadways including bridges5. On single lane bridges centre lines shall be discontinued 30m from each abutment.

For the more busy city streets a continuous white line, mm wide, may be used where it is desirable to discourage crossing of the line. The centre lines on a undivided 2-way street with 4 or more lanes shall be a continuous double white lines, each mm wide and separated by a space of mm.

In urban areas, the length and spacing of the strokesshould be less than those used for rural areas. A broken line is used to separate moving vehicles where there is unrestricted visibility and may be crossed at the discretion of drivers. A single unbroken line is used where the crossing of the line is to be discouraged or is legally prohibited, e. Double unbroken lines or combinations of unbroken and broken lines are used where crossing of the lines is legally prohibited unless in the latter case where the broken line of the combination as viewed by a driver is to the left of the unbroken line.

The dimensions of longitudinal lines are shown in Fig. The thickness of the longitudinal lines should be 3 mm to 5 mm when applied by SC.

If the actual no-passing distance is less than m, the additional length of marking shall be added at the beginning of the zone, unless the length of road with sight distance below the minimum required is less than 30m in length then no barrier lines are necessary. Where sucessive nopassing zones are less than m apart, the no-passing markings shall be extended to tekbik two zones.

The no-passing barrier lines should also be used on two-way roadways at pavement width transitions and on approaches to obstructions. It may also be used on approaches to intersections. Sight distance on a vertical curve is the distance at which an object 1. Similarly the sight distance on a horizontal curve is taken as the distance measured along the centre line between two points 1. On certain main urban arteries where traffic moves fast, however, the characteristics of centre line markings may be the same as for rural areas.

They should therefore be used: An unbroken line may be used to accentuate the lane marking in critical areas and more clearly define the traffic lanes where it is advisable to discourage lane changing, in locations such as interchange areas where unnecessary lane changing is jlan to smooth traffic flow.

The unbroken line may also be used to discourage lane changing especially at interchange areas. An alternative system is as shown in Fig. Edge lines are used wherever it is desirable to discourage travel on road shoulders and to make driving safe and more comfortable, particularly tekink night, by providing a continuous guide for drivers. They also act as a guide past object which are close enough to the edge of the road pavement to constitute a hazard.

The edge line of pavement with no marginal strip should be at least mm from pavement edge. On divided roads where the jjr is not sufficiently delineated, pavement edge lines may be provided on the right hand edge of each pavement. Application of edge lines is as shown in Fig. Examples of continuity lines used at ramp exits and entrances are shown in Fig.

Pavement-width transition lines teknikk be mm wide. Transition lines may be single broken, single unbroken, or double lines in accordance with the situation.

They shall be of standard design as for centre lines, lane lines or barrier lines. The required length of the transition line shall be determined by thePage 6A curve shall warrant a no-passing zone and shall be so marked where the sight distance is equal to or less than that listed below for the prevailing 85 persentile speed: The biginning of no-passing zone is that point at which the sight distance first become less than that point at which the sight distance again becomes greater than the minimum specified.

Figures 4 and 5 shows the methods of establishing no overtaking zones on vertical curve. Drivers must be given warning of their approach to any arrangement of double lines by three arrows on the carriageway directing them towards the left hand side of the road.

Approach warning arrows are usually positioned in zrahan centre of the carriageway. The dimensions and spacings of the arrows is as shown in Fig. Use jalann higher value when traffic volume are high. They shall extend across the traffic lanes approaching traffic signals or at STOP sign. Jk indicates the point behind which vehicles must stop when required. At STOP signs where visibility is restricted, the driver’s line of sight, the need for a pedestrian crossing and the clearance from traffic in the intersecting roadway should be considered when positioning the STOP line.

STOP lines shall generally be either parallel to the line of the intersecting roadway, or at right angles to vehicles approaching the line. They shall ordinarily be placed 1. In the absence of a marked crosswalk, the stop line should be placed not more than 10m nor less than 1. Refer to Figures 11 and If a stop line is used in conjunction with a Stop Sign, it should normally be placed in line with the stop line.

However, if a Stop Sign cannot be located exactly where vehicles are expected to stop, the Stop Sign line should be placed at the Stopping point. The holding lines or give way lines are to supplement the give way sign.

They should be placed not more than 10m nor less than 1. The triangular give way marking can be used to supplement this give way line. This shall consist of a series of strips mm wide. The width of the crosswalk should be from 1. They shall be broken lines mm wide with a stroke of am and a gap of mm. Transvere lines should be wider than longitudinal lines because of the narrowing which results from the low angle at which they are viewed. They shall be of non-skid materials and shall protrude 5 mm above the level of the carriageway.

Crosswalk lines at intersections controlled by traffic signals or stop sign can also be of solid white lines of mm wide 1.

They define jor island approaches,or obstructions, sealed shoulders, painted island and medians and areas separating exit ramps from the carriageway. An example is shown in Fig. They should be elongated in the direction of traffic movement in order that they may be legible at the maximum ditance. Legibility distance is increased by enlarging the length of characters. The dimensional proportions of letters and numerals should be as shown in Fig. A message should, if’ possible, be confined to one line.

If the message consists of more than one word, the first word should be nearest to the approaching driver. On high speed roads the space between the lines should be at least four times the height of the character.

For low speed, urban situations, the separation between lines may, if necessary, be from one-half to one times the character height.

Afahan messages for use on road pavements include the following: Pavement arrows as shown in Fig.
