Traffic signs manual: Chapter 5: Road markings

Product Information

Interactive training courses and educational material, to help you get the most from NBS software tools How sign faces are designed. This chapter does not include the various methods by which signs are constructed and mounted. It supersedes Local Transport Note ‘2/94 directional informatory signs interim design notes’, which was withdrawn in 1997. Chapter 8 (part 1) road works and temporary situations - design (ISBN 9780115530517) The current advice on the design and use of directional informatory signs is published in Local Transport Note ( LTN) 1/94. Also available is the latest list of primary destinations in England (PDF, 64.4KB), which supersedes the information in LTN 1/94. Chapter 3 regulatory signs (ISBN 9780115529252) ii) they must be either square or circular in shape. The sides of square or the diameter of circular studs must be not less than 95 mm nor more than 110 mm,

i) diagram 1040 may be used on the approach to a central reservation (including pedestrian refuge) of a single crossing in a two-way road (Schedule 4, Part I, para 3(2) of the Pedestrian Crossings Regulations), and diagram 1041 in a oneway road (para 4(2)), andMarkings for Zebra, Pelican and Puffin crossings are prescribed in the Zebra, Pelican and Puffin Pedestrian Crossings Regulations and General Directions 1997 (the Pedestrian Crossings Regulations). Toucan and equestrian crossings are marked using diagrams 1001.3, 1055.1 and 1055.2 prescribed in the Traffic Signs Regulations and General Directions 2002. More detailed guidance on the provision of pedestrian crossings can be found in Local Transport Notes 1 / 95 ( ISBN 0-11-551625-5) and 2 / 95 ( ISBN 0-11-551626-3). The length indicated in the first column consists of the controlled area detailed on figures 15-1 and 15-2, excluding the distance between the Stop or Give Way line and the limit of the crossing. to indicate a length of the edge of the carriageway which may be crossed. Green studs are used with markings to diagram 1010 (see paras 4.29 and 4.30) at lay-bys and to mark the boundary of acceleration and deceleration lanes on the left hand side of the carriageway. They must not be used in conjunction with Stop or Give Way transverse markings, or with diagram 1009. At lane-drop junctions, and right turnlanes, (see figure 7-7) green studs are used with the marking to diagram 1010 which demarcates the exit lane.

Thermoplastic material is applied hot and sets on laying. It may be applied by a hand or mechanical applicator. It has good durability and is suitable for use on all roads. Mechanical application is most suitable for use on motorways and other high standard roads where it can be laid in long runs using motorised equipment with minimum disruption to traffic. Road markings fall into two categories, those which must be illuminated with retroreflecting material, and those which may be so illuminated (regulation 31). Table [[#table23.1|23-1 lists the diagram numbers of markings which must be reflectorised. RED AND SINGLE YELLOW LINES CAN ONLY GIVE A GUIDE TO THE RESTRICTIONS AND CONTROLS IN FORCE AND SIGNS, NEARBY OR AT A ZONE ENTRY, MUST BE CONSULTED. Red lines are used on some roads instead of yellow lines. In London the double and single red lines used on Red Routes indicate that stopping to park, load/unload or to board and alight from a vehicle (except for a licensed taxi or if you hold a Blue Badge) is prohibited. The red lines apply to the carriageway, pavement and verge. The times that the red line prohibitions apply are shown on nearby signs, but the double red line ALWAYS means no stopping at any time. On Red Routes you may stop to park, load/unload in specially marked boxes and adjacent signs specify the times and purposes and duration allowed. A box MARKED IN RED indicates that it may only be available for the purpose specified for part of the day (eg between busy peak periods). A box MARKED IN WHITE means that it is available throughout the day.On dual carriageway roads and one-way streets, at least the standard pattern of eight 2 m marks should be laid on both sides of the crossing wherever possible (see also para 15.17).

Schedule 5 of the TSRGD 2016 covers signs that indicate parking places and areas subject to parking controls.

Crossings should normally be positioned at right angles to the carriageway edge. Where this is impracticable, the Give Way or Stop line should as far as possible be at a right angle to the kerb, even if it is then not parallel to the edge of the crossing. This ensures that drivers do not violate the overtaking prohibition when stopping at the line alongside other vehicles. It is not usually necessary to reflectorise waiting restriction lines as they do not normally have a guidance function. However, reflectorisation may be advantageous where such lines are used on the rural outskirts of a town and the road edge is unkerbed, or where a reflectorised edge of carriageway marking immediately precedes such markings. If the yellow lines are reflectorised, any associated parking bays should be also. The Specification for Highway Works published by the Stationery Office specifies which performance classes in BS EN 1436 for luminance factor, skid resistance and retroreflectivity are to be used on trunk roads and motorways. As higher retroreflective performance requires additional glass beads, which will reduce the skid resistance, it is not practicable to specify the highest performance class for both. A judgement will need to be made as to which property is more important at any particular location. Road marking materials and road studs are specified in the appropriate British Standards. These are generally the English language versions of standards published by the European Committee for Standardisation (CEN).As it is not possible to lay road markings to precise dimensions, and to allow for markings "spreading" in service, some tolerance in the prescribed dimensions is permitted by regulation 12. Specified values may vary by up to 5º for angular measurements and by the tolerances quoted in table 23-2 for linear dimensions. No tolerance is permitted for those angular or linear dimensions which are expressed as a maximum or minimum value. A tolerance of plus or minus 25 mm is normally allowed in the lateral positioning of lane lines. The Traffic Signs Regulations and General Directions ( TSRGD) 2016 prescribes the design and condition of use for traffic signs on or near roads in England, Scotland and Wales. Waiting restrictions indicated by yellow lines apply to the carriageway, pavement and verge. You may stop to load or unload (unless there are also loading restrictions as described below) or while passengers board or alight. Double yellow lines mean no waiting at any time, unless there are signs that specifically indicate seasonal restrictions. The times at which the restrictions apply for other road markings are shown on nearby plates or on entry signs to controlled parking zones. If no days are shown on the signs, the restrictions are in force every day including Sundays and Bank Holidays. The traffic signs manual gives guidance on the use of traffic signs and road markings prescribed by the Traffic Signs Regulations and covers England, Wales, Scotland and Northern Ireland. Revised editions of the manual will be published here as they are released.

Cold plastics are supplied in single or multicomponent forms. The product is laid on the carriageway and a cohesive film is formed by chemical action.

to indicate a line of studs which should not be crossed. It is used mainly to delineate the left hand edge of the running carriageway; studs are omitted at positions where traffic is permitted to cross, e.g. at lay-bys (where green studs are normally substituted). Where studs are used with chevron markings to diagram 1041, 1041.1, 1042 or 1042.1 they must be coloured red on both sides of the marking. Introduction and an outline of the historical, functional and design aspects of signs. The chapter includes sections dealing with the positioning and mounting of signs. Chapter 2 (in draft) informatory signs FOR X MILES" or "X YARDS" or, if appropriate, "NO ROAD STUDS FOR X MILES" or "X YARDS" (diagram 7012) should be used with the appropriate distance inserted. Where a crossing is situated close to a roundabout, the markings should never be extended into the circulatory area, and they should be subject to the restrictions described in para 15.20. The title of each working drawing reflects the respective Schedule, Part and Item in TSRGD 2016. The part of the title in parentheses refers to the TSRGD 2002 working drawing that it has replaced.
