Presentation ON PAVEMENT MARKINGS

1. Classification of Pavement Markings 1).Longitudinal Marking (LM) 2).Transverse Marking (TM) 3). Hazard Marking (HM) 4). Block Marking (BM) 5).Arrow Marking (AM) 6). Directional Marking (DM) 7). Facility Marking (FM) 1

2. The longitudinal marking are generally provided along the traffic movement. These are generally located parallel & adjoining to the traffic flow and help to separate the traffic flow in the same direction. These are generally white in color but when their color is yellow , it means traffic flow is in opposite direction. These lines marked on the pavement can be either broken, solid, double solid or dotted. Longitudinal Marking (LM) 2

3. Longitudinal Marking (LM) The centre line separates the opposing streams of traffic and facilitates their movements. Usually, no centre line is provided for roads having a width less than 5 m and for roads having more than four lanes. 1). Centre line; The centre line may be marked with either single broken line, single solid line, double broken line, or double solid line depending upon the road and traffic requirements. 3

4. 2). Traffic lane lines; The subdivision of wide carriageways into separate lanes on either side of the carriageway. At intersections, these traffic lane lines will eliminate confusion and facilitate turning movements. Traffic lane markings help in increasing the capacity of the road in addition to ensuring more safety. Longitudinal Marking (LM) 4

5. 3). No passing zones/Solid lines; Solid lines do not allow the drivers to cross between the lanes. No passing zones are established on summit curves, horizontal, curves. And on two-lane and three-lane highways where overtaking maneuvers are prohibited because of low sight distance. Longitudinal Marking (LM) 5

6. 4). Warning lines: Warning lines warn the drivers about the obstruction approaches. They are marked on horizontal and vertical curves where the visibility is greater than the prohibitory criteria specified for no-overtaking zones. They are broken lines with 6 m length and 3 m gap. A minimum of seven-line segments should be provided. Longitudinal Marking (LM) 6

7. 5). Edge lines: Edge lines indicate edges of rural roads that have no Krebs to delineate the limits up to which the driver can safely venture. They should be at least 150 mm from the actual edge of the pavement. They are painted in yellow or white. Longitudinal Marking (LM) 7

8. The marking provided across the carriageway for traffic control with broken lines, single/ double continuous lines . The transverse marking shall always be accompanied with corresponding sign. Transverse pavement marking are marked along the direction of traffic where immediate action is required by the driver. Transverse Marking (TM) 8

9. Transverse Marking (TM) Stop line must be marked where lanes approach the traffic control devices indicating the driver to stop the vehicle behind the line whenever required. 1). Stop Line: 2 ). Pedestrian Marking/Crossing- The pedestrian line indicate the movement or passage of pedestrian and indicates the drivers to slow down or to stop the when required. 9

10. The pavement marking that facilitating traffic merging/diverging, prohibiting to cross-over and to deflect the traffic ahead of hazardous situations. Chevron and diagonal marking, hatch marking and prohibitory marking and such markings are classified under Hazard Marking . This marking is used to indicate the driver of a hazard being the junction up ahead. Such as Prohibiting cross-over , changing of lanes, merging , or diverging. Hazard Marking (HM) 10

11. The zebra crossing for pedestrians, triangular and checkered marking for speed breakers and Giveway symbol which are painted in blocks on carriageway are classified under Block Marking The application of thermoplastic paint for block marking is generally different from longitudinal marking. The quality of block marking with adequate visibility is of utmost importance . Block Marking (BM) 11

12. 12 Block Marking (BM) Rumble strips, also known as rumble lines, rumble bars, or alert strips, are features on roads designed to alert drivers through tactile and auditory feedback.

13. The yellow box painted on intersections signals to drivers that they need to keep the space open. Cars are not allowed to stop inside the yellow box and block oncoming traffic. 13 Block Marking (BM)

14. The arrows painted on carriageway are meant to give direction for driver to take mandatorily. Drivers must take or follow these mandatory turns to avoid traffic confusion. ARROW MARKING (AM) Bi-directional Uni-directional 14

15. The word message which are directional nature are classified under Directional Marking. The characters of the message are elongated , so it is visible to the driver looking at a lower angle. Some directional words are : STOP , SLOW , EXIT ONLY ETC. DIRECTIONAL MARKING(DM) 15

16. This marking helps to facilitates the marking of vehicle and gives the driver an idea about parking space limits and restrictions. It also prevents encroachment of designated place like Bys stop, fire hydrant zones, etc. FACILITY MARKING(FM) 16
