AUTOMATION ON TRAFFIC
SIGNALS

2. INTRODUCTION
 Automation:- Automation is the use of various control system for
operating equipment such as machinery, traffic signals, processes in
factories, boilers and heat treating ovens and other applications with
minimal or reduced human intervention.
 The biggest benefit of automation is that it saves labour, save energy,
materials and to improve quality.
 Automation avoids Accidents and Medical emergencies such as fire,
road accidents, heart attacks etc. .
 Pre-emption of signals is generally done to assist emergency vehicles,
such as ambulances, so that response times are reduced.

3. INTRODUCTION
Automation- Traffic signals
 Traffic control has become major problem on the roads of many cities.
 Some emergency vehicles like ambulance ,fire brigade and some
important security conveys get stuck in traffic and have to wait which is
not desirable.
 Main aim of this problem is to provide wireless sensors to the traffic
signal, so that signals can sense the ambulance siren and control the
traffic light signal. Ambulance will reach the hospital in stipulated time
so that the human lives can be saved.
 The application of this automation is to reduce the traffic density when
required.

4. TRENDS
 Traffic pre-emption devices are implemented in a variety of ways such as
acoustic devices, line of sight, and localized radio signals.
 Acoustic Systems use audio sensors to detect the pattern of waves from the siren
of an emergency vehicles like ambulance.
 Use of GPS hardware to receive and transmit GPS signals. These signals are
transmitted to a central server which can communicate to traffic signal controllers
via Internet.
 •Smart Traffic Management: Using traffic data obtained from various sources such
as Google Traffic and Traffic updates from ground controllers, the same server-
centric model, using the same microcontroller can be used to slightly manipulate
and vary traffic signal timings to ease congested roads.
 The microcontroller can be used to display traffic updates on LED screens at
traffic signals, so commuters can avoid congested routes.•

5. TRENDS-NEXT FIVE YEARS
Architecture An ambulance (with an Android device) receives GPS coordinates from
satellites and then transmits the coordinates to the server.
• Cameras, speed detecting sensors and other sensors can also be connected to
the same controller and violations can be viewed automatically at the Central
office.
• Automated closing and opening of Traffic signals for ambulance.
• Dynamic display of ambulance arrivals at hospital to take precaution in
advance for critical cases.
• Problem of satellite signal in reaching GPS receiver using sensors like IR
detectors receiver module extended with automatic turn off when no vehicles
are running on any side of the road which helps in power consumption
savings.

6. INTEREST AREAS
 My interest is to prevent traffic and save the human precious lives.
 Automation is used where the traffic signals is kept and in many other
places where we need to full fill the need of the automation.
 Development of this project is to tackle the vehicular traffic on roads.
 I will intent to work on satellite signals in reaching GPS receiver
without any delay so that the traffic can be controlled and the human
valuable life can be saved.
