This document describes different types of traffic control devices used to regulate traffic flow and ensure safety. It outlines various sign types like regulatory, warning, and informational signs. It also discusses traffic signals, road markings like solid and dashed lines, arrows, and colors that impart instructions. Pavement markings are described for different road configurations. Traffic islands are defined as raised areas that physically guide vehicle movement. In summary, the document provides an overview of common traffic control devices and how they inform and direct drivers, pedestrians, and bicyclists.

including pedestrians, motor vehicle drivers and
bicyclists. These devices are usually placed adjacent, over
or along the highways, roads, traffic facilities and other
public areas that require traffic control.

– message to the drivers about the need to stop , give way and limit
their speeds.
– They are of three types-
 REGULATORY SIGNS

7. Signals:
Vertical signal Horizontal Pyramid (left
turns):
 Devices which could alternately direct
the traffic to stop and proceed at intersections using
red and green traffic light signals automatically.
RED = STOP YELLOW = STOP IF SAFE GREEN = PROCEED WHEN
CLEAR . Now Types Of Signals:

8. Road Marking :
SOLID = NO DASHED = PASSING
DOUBLE MARKING
– GO BY THE MARK
CLOSEST TO YOU
PAVEMENT ARROWS –
HAVE TO PROCEED IN
THE DIRECTION OF THE
ARROW
 Road marking are made of lines , pattern , words ,symbol or ref
lection on the pavement , kerb , sides of islands or on the fixed
objects within or near the roadway.
 WHITE STOP LINES- shows where to stop at stop signs or traffic
signals
 YELLOW EDGE LINES- separate the shoulder from the travel lane
and show the edge of the highway

9. Pavement Markings:

10.  Kerb Marking-
These may indicate certain regulation like parking regulations.
Also the marking on the kerb and edges of islands with alternate
black and white line increases the visibility from the a long
distance.
 Object Marking-
Physical obstruction on or near the road hazardous and hence
should be properly marked.
 Reflect Unit Marking-
Ref lector markers are used as hazard markers and guide markers
for safe driving during
night. Hazards markers ref letting yellow light should be visible
from a long distance of about 150 m.

11. TRAFFIC ISLANDS:
 Traffic islands are raised areas constructed within the roadway to establish
physical channels through which the vehicular traffic may be guided.
Divisional islands
Channelizing islands- Pedestrian Loading
Islands Rotary islands
