These signs have been made available in 5 charts: Note: The following chart has been made available from Lets Look, K53 Mobile Application to Test Your Knowledge of the Rules of the Road, Introduction: It has become increasingly difficult to steal motor vehicles with all the anti-theft devices, such as immobilisers, gear locks, etc.

5 Roads are therefore broadly classified as RURAL or URBAN and specific differences in signface display rules are related to these basic categories. Such standards are either under development or are provided as part of contract documentation or departmental specifications. 7 generally a rectangular shape.

Provision has been made for the signing of a much wider range of types of public transport vehicles. 2 The text is subdivided into the following numbered MAY 2012 Text Conventions 1 Traffic control devices include all road traffic signs and other devices, including delineation devices, used to regulate, warn, guide or inform road users.

Typical of these differences are: (i) in the recommended system the primary traffic signals are positioned on the far side of junctions, whilst in the alternative system the primary traffic signals are positioned on the near side of the junction; (ii) in the recommended system the basic traffic signal sequence is red, green, yellow, red, whereas in the alternative system the basic traffic signal sequence is red, red plus yellow, green, yellow, red.

The decision whether or not to use a particular device, and, if one is to be used, the decision on how it shall be used, should be made at the very least on the basis of an inspection of the site.

Objective priorities depending on the importance of the task and of the road should be set. endobj 1.3.2 1 1.3.1 REGULATORY signs have legal significance. SADC - RTSM - VOL 1 GENERAL PRINCIPLES ROAD TRAFFIC SIGN CLASSIFICATION 1.3.2 9 GUIDANCE signs are essentially those signs previously classified as INFORMATION signs, which had a directional or guidance (navigational) function rather than simply an information function. This volume therefore covers the meaning and application of individual traffic control devices available to authorities having the necessary jurisdiction to place or erect such devices in a public road. 7 Section 3.0, page 3.0.1, shows the colour code used for the warning sign class, for both PERMANENT and TEMPORARY categories. You can get Adobe Reader here. The secondary message portion of selective restriction signs shall use the same background, symbol and border colour code as the main sign above it.

It is mandatory for all users to know k53 hand signals so that they can use them or recognize them when other drivers use them along the way. Only when illuminated by a focused light source will the surface appear significantly brighter than a similarly illuminated ordinary surface, because the ordinary surface scatters the light directed on it. For details of road markings refer to Chapter 7, and for application examples to Volume 2, Chapter 2. Volume 2, if required, will deal with the collective application of signs, markings, and signals for specific subject areas such as traffic accommodation at roadworks, tourism signing, public transport signing and signing for the control of heavy vehicles. 2 An authority may specify a retroreflective background for signs which are not required by regulations to have a retroreflective background. 1.1.3 Road traffic signs, by legal definition, include all prescribed road signs, road markings and traffic signals, and are to be used solely for the purpose of traffic control and are not an advertising medium. Knowledge of your K53 road signs is imperative for all users regardless of whether you are a driver, cyclist, or pedestrian because this improves safety for everyone. On the other hand this field of view may have some particular environmental or aesthetic value. This group of signs is subdivided into a wider classification as follows: (a) (b) (c) (d) (e) (f) (g) 8 CONTROL signs; COMMAND signs; PROHIBITION signs; RESERVATION signs; COMPREHENSIVE signs; SECONDARY MESSAGE signs; DE-RESTRICTION signs. Specific site factors and the presence of other devices will influence the use of a proposed new device. by the use of blue, green or other background colours.

Equipment capable of measuring the appropriated values is becoming more freely available and any authority setting up a road traffic sign management system should initiate a programme of sign measurement to establish sign life prediction patterns. 3 All words used on road signs should be displayed in the manner normal for printed matter, using upper and lower case letters, with the exception that the names on all LOCATION signs or LOCATION information Use of these numbers may assist message transfer because: GENERAL PRINCIPLES This Edition of the Manual introduces a wide range of new symbols for use on regulatory, warning, guidance and information signs, markings and signals. We believe this article was helpful, if yes, dont hesitate to share this information with your friends on Facebook, Twitter, WhatsApp, and other Social Platforms. The condition of a sign may be determined objectively be measuring the contrast and retroreflectivity of the sign with standardization equipment, or subjectively by assessing the night-time visibility of the sign under bright and dim headlight illumination and its daytime contrast to background clutter. Three of these grades are specified in SANS 1519, namely Class I, Class II and Class Ill. Whilst the standard specification requires compliance with durability tests, the suppliers of materials are commonly prepared to provide a warranty for the above classes of material, provided various conditions are complied with during manufacture. In co-ordinating remarking and resurfacing operations, the effect of an inadequately marked road should be very carefully considered before remarking is postponed for any length of time. US Department of Agriculture - Forest Service. The message which should be inferred by an observer of TEMPORARY signs is that normal standards may not apply, and as a result, a higher level of attention to surrounding circumstances, which are not normal, is required. (d) planning of road sign, traffic signal and road markings improvement programmes; (e) controlling and optimizing field maintenance; (f) analysing the effectiveness of various traffic control devices; (g) monitoring performance for specification development. Variable message signs are covered in Chapter 9 and in Volume 2. The text covering each sign, marking and signal starts with a statement regarding the meaning, or significance, of the device.

What are the colors of road signs? CONSULT, content I-VIII.qxd 2 The majority of new signs are regulatory signs and several new symbols have been provided. 4 Guidance and information signs are RECTANGULAR with a few exceptions as follows: of a hazard ahead are (a) ROUTE MARKER sign GE15 (RSA National) PENTAGON; (b) ROUTE MARKER sign GE14 (RSA Provincial) DIAMOND; (c) RIGHT OF WAY sign IN7 - DIAMOND. Within these classes the road types have been further subdivided into four groups, namely CLASSES A, B, C and D, as indicated in Figure 1.4. It should be noted, however, that different designatory letters are used in member countries to identify classes of route which have essentially the same characteristics as similar classes of route in other member countries. London: TSO This sign alerts you that there is a roundabout ahead. 3 Signs which WARN TRIANGULAR. 4. %PDF-1.5 9 Shape, size and colour are also relevant for road markings and traffic signals, however, the colour code of road markings is not specifically related to function such as "regulation" or "warning", and traffic signals have limited variations in shape, size and colour. Road signs for learners licence are categorized into three types, which include regulatory, warning, and guide signs. A warrantied Class I material is considered to have an acceptable level of degradation due to weathering over a 7 year life, whereas warrantied Class II and Class III materials are considered acceptable over a 1.5.2 Dimensional Tolerances 1 SANS 1519 refers to this Manual stating that "the layout of the message on the signface shall conform to the layout, given in the applicable drawings of the Manual, so that no deviation exceeds 5% of the layout of the applicable drawings". Colour contrast, and therefore legibility, is normally sought by placing a dark SADC - RTSM - VOL 1 MAY 2012 SPECIFICATION AND MANUFACTURE letter on a light background, or vice versa. Uniformity in application MAY 2012 (a) using sign material that will continue to perform even though damaged; SADC RTSM VOL 1 GENERAL PRINCIPLES ROAD TRAFFIC SIGN MAINTENANCE 1.10.2 (b) substrate stiffening; (c) using rods or vanes at the bottom of posts to prevent rotation or removal; (d) installing signs high enough not to be in easy reach (especially smaller signs); (e) using the maximum lateral offset from the roadway edge where it is possible; (f) restoring vandalised signs as soon as possible to curtail a perception that the vandalism of signs may be acceptable practice; (g) implementing an anti-vandalism programme.

In order to accommodate specific needs of member states several chapters in Volume 1 have a final section dealing with what have been termed "national variants". The classification detailed in this section therefore covers all three sub-categories of road traffic signs. Page 1 1.5.5 1.5.3 Road Marking Materials Limited comments on specifications of road marking materials are given in Chapter 7. Only uppercase letters and numerals are available in this letter style. As a general rule a luminance ratio and a coefficient of retroreflection ratio between the text or symbol colour, and the signface background colour, should be at least 7 to 1 and preferably 10 to 1. 4 limit total amount of information. 1.4.4 Colour 1 Colour on its own is not considered a significant factor affecting the conspicuity of a road traffic sign when compared, message for message, with a white sign with black text (an "achromatic" sign). These traffic symbols tell you what to do. The meanings given in the Legislation have legal precedence. The majority of these important traffic symbols have a rectangular shape with a black legend on a white background. Traffic control devices are thus used to achieve an acceptable level of road safety by providing for the orderly and predictable movement of all traffic, vehicular and pedestrian, throughout all levels of the road network. 4 fulfil an important need; command attention; convey a clear, simple meaning; command the respect of road users; give adequate time for response. 2 To be effective they should meet the following basic requirements: (a) (b) (c) (d) (e) promotes road users' observance and avoids excessive or unwarranted use of road traffic signs. The hijacker has the element of surprise and this is a concern. The South African system, having recently been developed to conform to European signing principles, but also to satisfy African requirements, contained a significantly greater number of road traffic sign types. Page numbers are restarted in each section e.g.7.1.1, 7.2.1, 7.3.1 etc. Home Blog Road Signs In South Africa And Their Meaning 2022 [Complete Lists]. Because the physical appearance of signs is apparent to all road users, the quality of this appearance has a high profile in crediting or discrediting the authority or authorities responsible for the provision and/or maintenance of signs. Virtually all road signs may be used in either a PERMANENT or TEMPORARY form. road users; road authority officials; traffic officers; those involved in vehicle driver training; traffic control device manufacturers; international visitors. Most definitions, however, recognize management to be a process of i nfluencing members of an organization and using organizational resources systematically to achieve stated organisational objectives. The commonest road sign is the STOP which even kids know its meaning. TRAFFIC SIGNS Official Edition For example; As the name suggests, these signs indicate that space is for specific vehicles. Volume 1, Chapter 6: Traffic Signals, therefore covers the differences between the two systems in parallel. AASHTO - Select committee on highway safety. 2 A range of text conventions have been used to place emphasis where this has been deemed necessary. The limits of the area are thus defined by four "x" and "y" co-ordinates for each colour. In this regard the use of retroreflective materials to achieve adequate conspicuity of a sign at night may reduce the night-time legibility of the message compared to that achieved in daytime. 2 There is general acceptance of the method of specifying colour in terms of the trichromatic system recommended MAY 2012 For manufacturing control purposes the required colours have been specified in terms of an area on the "Chromaticity Chart". Whilst a high visibility background is rectangular and may itself offer a lower level of edge definition against the background, its function is to significantly improve the target value of the whole sign, and to give better edge definition, and hence shape recognition, to the superimposed sign. 1.1.10 Use of Numbers on Direction Signs 1 Numbers have been allocated to the main routes i n the road network to give a concise collective description to what is commonly a lengthy piece of road (in a similar way that postal codes serve to identify fairly large areas). 2 Several types of road marking materials are in use ranging from the solvent based non-reflectorised paint to thermoplastic retroreflectorised material and preformed reflectorised tapes. Maps are essential for this purpose.

5 Emergency maintenance tasks on traffic signals also include: (a) repairing damage to signal installations because of vehicle accidents; (b) repairing damage to vehicle detectors because of excavations or other roadway maintenance operations.

The use of a uniform specified or manufactured traffic control device does not in itself constitute uniformity. This function is termed the "attention conspicuity" of the sign and refers to the ability of a sign to attract attention when an observer's (driver's) attention is not specifically directed to the probable occurrence of the sign. 2 0 obj Uniformity of device and application is essential to law enforcement and for traffic safety. [Wikipedia].

The meaning attached to these terms. 1.11.2 Road Traffic Sign Management Systems 1.11.6 Costing 1 Depending on the objectives of the authority establishing a road traffic sign management system, a system should be set up in such a way that it can be developed into a sign maintenance management system. DONE AT , on this . Day of , 1999. (2) An authority may specify Class Ill in place of Class II if satisfied that this i s cost effective (see Subsection 1.5.3). 2 Significant factors in determining the effectiveness of road traffic signs are an assessment of the uniformity of the display of signs and an assessment of the performance of the signs based on their condition. Road signs may be provided as PERMANENT or TEMPORARY signs and the colours used for a specific sign change according to such use (see Subsection 1.4.4 and Chapter 10). 2 The shape, size and colour of a road traffic sign contribute to its conspicuity and to the transfer of its primary function or class, and its specific signface message. This will enable effective checking of the quality of the material supplied and will almost certainly result in a sign life which is cost effective over time. Address: Copyright 2022 PDFCOFFEE.COM. These findings were considered by SATCC in September 1995. This together with a junction identity number could well contribute to reduced repair times. But, as a driver, there are other road signs you need to know to help you survive in the midst of your fellow drivers. a Class I (white) on a Class III (green) might result in a similar effect at night. The video shows the time to be 05h26 and the vehicle to be driving at a speed of 100Km/h. When there is little luminance contrast between an achromatic sign and the GENERAL PRINCIPLES (i) COMMAND -white on blue with a white border; (ii) PROHIBITION - black on white with a red order; (c) RESERVATION and COMPREHENSIVE signs which are rectangular in shape are differentiated by their colour code: (i) RESERVATION- white on blue with a white border; (ii) COMPREHENSIVE - white on blue with a red border.

YEB As a general rule a contrast ratio of the coefficients of retroreflection of colours placed on each other, irrespective of class, is recommended as follows: (a) for small, finely detailed areas (letters and symbols)- a minimum ratio for light-to-dark of 7 to 1, with a preference for 10 to 1 or more; (b) for large areas (arrows or blocks) - a minimum ratio of 3,5 to 1, with a preference for 5 to 1; or recommended retroreflective material class combinations are given in Table 1.1. On the one hand it is considered necessary to communicate a message to road users and in order to do GENERAL PRINCIPLES SADC - RTSM - VOL 1 MAY 2012 Fig 1.3 MAY 2012 Key to Colour Coding SADC RTSM - VOL 1 GENERAL PRINCIPLES ROAD TRAFFIC SIGN MAINTENANCE 1.10 1.10.1 ROAD TRAFFIC SIGN MAINTENANCE 1.10.1 General 1 The basic functions of road traffic signs are to regulate, warn, guide and inform road users, during daytime and night-time and under all weather, climatic and traffic conditions. Table 1.1 indicates sign retroreflective backgrounds. 2 3 4 This Third Edition has been developed from a harmonization of the earlier SATCC Road Traffic Signs Manual, and the Third Edition of the South African Road Traffic Signs Manual which contained a wider range of signs. You will require, to be installed on your PC to open the file. background the introduction of even one colour (say as a border colour) serves to create a colour contrast between the sign and the background (a "chromatic" sign). Inventories Inventories including road signs, traffic signals and road markings should be developed with the objective of providing information that will address some or all of the following applications: (a) assessing traffic control device adequacy and visibility; (b) analysing the need to upgrade traffic control devices to meet uniformity and application standards; (c) providing the means to obtain information about traffic controls for continuous monitoring and adjustment to optimize traffic safety and operations; MAY 2012 1.11.7 Priorities 1.11.8 Execution 1 Execution sub-systems could include a wide range of activities like scheduling, procurement, inventory control and cost allocation, all at varying l evels of sophistication.
