ROAD MARKING:-
Road or traffic marking are
made of lines, patterns, words, symbols or reflectors on the pavement, kerb or
near the roadway. The markings are made using paints in contrast with colour
and brightness of the pavement or other back ground. Light reflecting paints
are also used for traffic marking. Traffic markings are various types:
[1]
Pavement markings: - Pavement markings may
generally be of white paint. Yellow colours are markings used to indicate
parking restrictions and for the continuous centre line and barrier line
markings. Pavement markings are different types which are as:
(a) Centre line: - These are meant to separate the
opposing streams of traffic on undivided two-way roads. On rural highway two or
three lanes, simple broken lines of width 0.1mt and length 4.5mt segments and 7.5mt
gaps may be painted on straight stretches of NH and SH.
(b) Lane Line: - Lines are drawn to
designate traffic lanes. These are used to guide the traffic and to properly
utilize the carriageway.
(c) No Passing Zone Markings: - These
are marked to indicate that overtaking is not permitted.
(d) Turn markings: - These are useful
near intersection to designate proper lateral placement of vehicles before
turning to the different directions.
(e) Stop Lines: - These are meant for vehicles to stop
near the pedestrian crossing, signalized intersections etc. where the vehicles
have to stop and proceed.
(f) Cross Walk Lines: - The particular
places where pedestrians are to cross the pavement are properly marked by the
pavement markings. The width of pedestrians crossing may be between 2.0 to
4.0mt depending on local requirements.

Kerb Lines

Kerb Markings: - These may indicate certain
regulations like parking regulations. Also the marking on a kerb with alternate
black and white line increase the visibility from a long distance.

Object Markings: - Physical obstruction on or
near the roadway are hazardous and hence should be properly marked. Typical
obstruction is supports for bridge, sign and signals, level crossing gate, etc.

Reflector Unit Markings: - Reflector
markers are used as hazard markers and guide markers for safe driving during
night. Hazard markers reflecting yellow light should be visible from a long
distance of about 150mt.
