3. The overall design of Traffic control signal system
also known as traffic lamps, signals lights and stop
lamps.
Traffic light display three lights of a standard colour
Lights are simultaneously change with given time
4. Since vehicles and highways are increasing
day by day, so it’s a great challenge for us
to control traffic by human and it also
expensive .
This project presents a possible solution
where our road authority can set this device
to control traffic signal system without any
confliction
5. .4 ways traffic control system is a automated traffic
controlling system.
This system gives you access to control 4 ways
highway lane traffic signal simultaneously based on
the time
The primary function of any traffic signal is to
assign right-of-way so that no confliction occurs
at an intersection.
6. RED light – instructs the driver to STOP at the
intersection
YELLOW light – instructs the driver to WAIT (If
red light is next) or GET READY (if green light
is next)
GREEN light – instructs the driver to GO
through the intersection
7. To control vehicles without
confliction.
Saves money.
It helps our road authority to
decrease traffic jam.

10. A potentiometer is a manually adjustable variable resistor with 3
terminals
The potentiometer essentially functions as a variable voltage
divider.
This type of pot is often used in audio volume control

13. YELLOW light – instructs the driver to WAIT (If
red light is next) or GET READY (if green light is
next)
15. To make our traffic system digital.
To reduce cost.
to provide non stopable service instead of any
types of natural calamites.
Time can be increased or decreased as we want
16. Saving energy
Control the time intervals of traffic light.
Overcome any types of vehicles confliction
LED is driven by electrical energy directly into
light, the heat generated is very low,
LED traffic lights response faster than halogen
bulbs
17.
18. The circuit can’t be used in metro city or
where traffic is more.
If power is off, device will automatically
stop.
There is no sensory input & decisions.
There is no way to detect a corrupted
vehicles
LED’s can shift color due to age and
temperature
