Traffic control involves directing traffic around disruptions to ensure safety. It uses devices like signs, signals, and pavement markings to inform and guide drivers, pedestrians, and bicyclists. Traffic lights control intersections with red, yellow, and green lights, while signs communicate regulations, warnings, route information, and temporary controls through shapes, colors and messages. Pavement markings supplement signs to regulate lanes and guide traffic. Variable message signs and channelizing devices also direct traffic, especially through work zones. Overall, the goal of traffic control is to facilitate safe and efficient traffic flow.

3. Road traffic control involves directing vehicular
and pedestrian traffic around a construction
zone, accident or other road disruption to
ensure the safety of emergency response teams,
construction workers and the general public.
Road traffic control
Traffic control also includes the use of
CCTV and other means of monitoring
traffic by local or State roadways
authorities to manage traffic flows

4. Traffic control Devices
Traffic control devices are markers, signs and signal devices used to inform,
guide and control traffic, 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

5. Types of Traffic control Devices
Traffic signs
Variable Message Signs
Road surface markings
Channelizing devices
Traffic lights

6. Traffic Lights
Traffic lights, which may also be known as
stoplights, traffic lamps, traffic signals, signal
lights, robots or semaphore, are signaling
devices positioned at road intersections,
pedestrian crossings and other locations to
control competing flows of traffic.

7. Illumination of the red signal prohibits any traffic from
proceeding
Illumination of the yellow/amber light denoting, if safe
to do so, prepare to stop short of the intersection,
Illumination of the green light allows traffic to
proceed in the direction denoted,

9. A traffic sign is defined as a device mounted on a fixed or portable
support whereby a specific message is conveyed by means of words
or symbols.
Traffic Signs
The sign is placed or erected for the purpose of regulating, warning,
or guiding vehicular, pedestrian, or bicycle traffic.

11. Types of Traffic Signs
Regulatory Sign
Warning Sign
Informative Sign
Temporary Traffic Control Sign

12. Warning Sign
Informative Sign
Temporary Traffic Control Sign

13. Traffic Signs Design
Shape, color, Size, composition, lighting or retro-reflection should
command attention and convey a simple meaning. It
Should have:
i. High visibility by day and night
ii. High legibility

14. Traffic Signs Limitations
Easily damaged due to impact or vandalism
Visual quality degrade over time due to dirt and normal
reflectivity deterioration
Require continuous maintenance

15. Pavement Markings
Pavement markings are all lines, patterns, symbols, words, colors, or
other devices, except signs and power-operated traffic control devices,
set into the surface of, applied upon, or attached to the pavement or
curbing and placed for the purpose of regulating, warning, or guiding
traffic

17. Why Pavement Marking ?
Display regulations (no passing zones, curb parking restrictions)
Supplement other devices ( STOP lines, symbol arrows)
Guide traffic (lane lines, rout number)
Warn traffic (SIGNAL AHEAD, rail-highway crossing legend)

18. Types Of Pavement Marking
Longitudinal Markings (parallel to the roadway)
Transverse Markings
Parking space markings
Word markings

19. VMS are electronic traffic control signs which can exhibit different traffic
messages according to the needs of a specific road. Permanent VMS
displays are mounted on large sign structures overhead or alongside the
road. These devices are often placed on urban freeways which have traffic
problems. Portable VMS panels are usually mounted on trailers, although
some may be carried by trucks
Variable Message Signs

21. Channelizing devices are used to warn drivers and pedestrians and to guide them
through a work zone. Common channelizing devices are traffic cones and drums.
These types of traffic control devices are usually placed between traffic and road
construction zones, or between opposing traffic streams.
Channelizing Devices
Example: Traffic cones
Tubular markers
Construction barrels
Vertical panels

23. Safety First
Keep on your left, allowing the vehicles from the opposite direction to pass
Give way to traffic on your right, especially at road junctions and round about
Keep enough distance from the vehicle ahead to avoid collision
Do not drive in a zigzag manner
Always use a helmet if on a two-wheeler and always check that the strap is fixed properly

24. BETTER LATE THAN NEVER

25. With desperate need for TRANSPORTAION for industrial purpose
and business facts of country we should modify our TRAFFIC
CONTROL SYSTEM. Beside we should mind about the road safety
which is first.
Everyone should aware of accidents and helps to achieve a perfect
and comfortable journey. We are grateful to our respected faculties
for getting opportunities to present such a real and serious topic.
This presentation has highly influenced us and learnt us about the
awareness and safety of driving.
