ROAD MARKINGS
FUNCTIONS
• ROAD MARKINGS ARE USED AS A MEAN OF CONTROLLING & GUIDING TRAFFIC.
TYPES OF ROAD MARKINGS
CARRIAGEWAY MARKINGS ARE APPLIED TO CARRIAGE WAYS
OBJECT MARKINGS ARE APPLIED TO TRAFFIC ISLANDS, CULVERT
HEADWALLS, PIERS, ABUTMENTS,ETC
Kerbs • A curb or kerb is the edge where
a raised pavement / sidewalk /footpath, road median, or road shoulder meets an unraised street or other roadway. Typically made from concrete, asphalt or long stones (often granite), the purpose is twofold: first as a gutter for proper drainage of the roadway, and second for safety, to prevent motorists from driving onto the shoulder, median, sidewalk or pavement.
ABUTMENTAn abutment is, generally, the point where two structures or objects meet.Specifically, an abutment may be:
• the part of a structure that supports an arch.
• the tooth or teeth that support a fixed or removable bridge.
• the part of an implant that acts as a connection between the implant and the crown.
PIERSA pier is a raised structure, including bridge and building supports and walkways, over water, typically supported by widely spread piles or pillars.
TRAFFIC ISLANDA traffic island is a solid or painted object in a road that channelizes traffic. It can also be a narrow strip of island between roads that intersect at an acute angle. If the island uses road markings only, without raised kerbs or other physical obstructions, it is called a painted island.
CULVERT• A culvert is a device used to channel
water. It may be used to allow water to pass underneath a road, railway, or embankment.
General principles of longitudinal pavement markings
• Solid lines are restrictive in nature & it is an offence to cross or straddle such a line.
• Broken lines are restrictive in character & vehicles can cross such a line provided this can be done with safety.
• When a combination of a solid & broken lines is used, a vehicle should not cross the continuous lines adjacent to
• Double lines indicate maximum restriction.
