Abstract - In today’s world where increase in population has
led to massive increase in number of vehicles on road. As the
number of vehicles on road has increased it leads to massive
roadblocks even when traffic signals are installed at that
junction. Due to these traffic jams the emergency vehicles like
ambulance which carries critical patients with themarestuck
in these traffic jams and are delayed reaching their
destinations or hospitals. In this proposed system the focus is
on clearing all roadblocks at the signals in advance before the
ambulance reach any signal on its path by using centralized
controlled system monitoring all the signals on its path.
Key Words: Android application, GPS, Traffic Signal,
Transmitter, Receiver.
INTRODUCTION
The modern world is evolving at great speed, this has given
rise to the term called comfort. Everyone in this world has
inclined towards the comfort for his needs, these needs
include comfort of having personal cars for travelling which
is at any time convenient for him. This mode of comfort has
given rise to the traffic problems as everyone has his own
vehicles. These many number of vehicles onroadsometimes
lead to traffic jams. Most of the cities have implemented
traffic signals at major junctions to tackle this problem, yet
they fail many times due to ever increasing traffic. As a
result, there are long lanes of vehicles. In such situations
emergency vehicles like ambulances face major problemsas
these are the vehicles which have the priority to reach the
destination on time or within short amount of time, but due
to such long traffic jams or road blocks theytakelongtime to
pass the traffic signals in short time. The latest report from
National Institute ofEmergencyMedicine(NIEM)showsthat
20% of patient lost life because of the ambulance delays and
major factors in delays of these vehicles is traffic jams,heavy
traffic or long signal timings.
Hence to tackle such importantissueinthisproposedsystem
states that the use and implementation of the latest
technology such as smart traffic signals, centralized cloud-
based system and mobile application to make sure that
ambulance reaches the targeted destination within time
without getting stuck in the jams.
2. COMPONENTS
Fig -1: Overview of Proposed Design
2.1 SMART TRAFFIC SIGNAL
The smart traffic signal in this system plays an important
role in the whole system as it will act as normal signal with
usual stop and go timings, but it will change its functionality
when it will get notification or alert about the incoming
ambulance on its way. Signal will act as per the instructions
given by the centralized system where all the signals will be
connected to make system more practical and effective.
2.2 CLOUD BASED CENTRALIZED SYSTEM
The Cloud based centralized system will act as the backbone
to the whole system, where it will govern the whole system.
This will have the task to coordinate all the signalswitheach
other, by this all the signals will act in synchronization. This
cloud-based application will take the input from the mobile
application and give output to the signals which will be part
of route in that respected travel. The mobile application will
first set the shortest route to reach the destination and will
forward that route to this system, where this system will
take that as an input and will map all the signals on that
route. After getting all signals on that route it will count the
distance of each signals from the destination, this way it will
plot the rankings for each signal and it will determine the
priority of each signal. After setting priority for each signal
this system will give command to each signal on basis of its
priority.

This way it will instruct the signals on the way when to go
green/free. The timing for signal to set free/green will
mostly depend on the time required for the ambulance to
reach at each signal.
2.3 MOBILE APPLICATION
An android based mobile application will act as an input
provider to whole system where user will have all the rights
(this application should be installed in the mobile phone of
the driver or it should be integrated to the ambulanceitself).
This application will have the input field inwhichuserneeds
to set the destination, using this as an input system it will
locate the destination on map and will try to find the
shortest route to reach that destination. In this way the
application will find the shortest route to reach the
destination. After finding the shortest route it will track the
vehicle and with the help of the GPS tracker it will track the
vehicle, and on the basis of that it will decide if the
ambulance is following the track or not. On the basis of all
these it will locate all the possible signals on the way andthe
cloud-based system will set freethesignalswhenambulance
is not far away or just five minutes away from the signal.
The mobile application is restricted to only authorized
person. The authorized person should pre-register to the
application.
3. WORKING
The working of the model is an integration of all the
components working on parallel.
The driver of an ambulance first needs to launch the
application installed in his phone. Next step is to type the
destination, while picking up the destination the application
will pick the GPS location of device to set it as a source of
location. After taking input of destination and setting source
location the application will search for the fastest route with
minimum signals in path. Then it will look for the traffic on
those particular tracks which is selected by the application.
It will use google API’s for searching for route and for traffic
data.
Fig -2: Flow of System
After getting fastest route for the destination the app will
plot or identify all the signals on the route, after that it will
set the priority for each signal as per its distance from the
source. The nearby ones will have the highest priority
whereas the farthest will have the lowest priority. These
priorities will decide at what time which signal to set free.
This information about the priority of each signal will be
sent to the centralized system where all the signals are
connected and it will have the right to change functioning of
any signal on its way for time being. The centralized system
will count the time for ambulancetoreacheverysignal andit
will set free signal when ambulance is five minutes away
from the destination. In this way, ambulance will have the
steady flow of traffic and it will not be caught in any
roadblocks.
4. IMPLEMENTATION
This proposed system consists of number of latest
technologies for its implementation which involves smart
signals, centralized system, and android based mobile
application. All these technologies are a sort of huge
implementation of their own viz smart signals. The smart
signal should be installed at every road junction, the android
app must be pre-installed in the phone of authorized person.
The centralized system should have the whole control over
the traffic signal forcontrolling the timing wheneverneeded.
For the purpose of sending and receiving the alert or
notification transmitters and receivers will play crucial role.
The mobile application send all required information to
centralized system via wireless network, the centralized
system will have set of transmitters and receivers installed
which will receive and pass the signal to traffic signals.

Fig -3: Implementation
The receiver block of centralized system will have MCS-51
and TRW 2.4 and main controller will have only single MCS-
51. The traffic signal will have single MCS-51 installed in
each one of them.
5. LIMITATIONS
Even if this proposed system has scope it has its own
limitations as well. Major problem with the system is
implementation of smart signal. As of today, there are no
smart signals implemented anywhere, hence these signals
should be implemented throughout the city for better and
proper implementation of system.Anothermajorproblemis
people inside the cars, these people will not cooperate
willingly as most of the peopleconsidertheirowncomfort as
priority than helping someone in need. The major
complications can be occurred at the road junctions where
hospital is located, here it can be possiblethatmorethan one
ambulance can arrive at the signal at a same time in such
cases the system cannot decide which signal to set
free/green. The one-way solution for such complications is
to set a priority index in the android application, hence by
considering the severity priority can be assigned.
6. CONCLUSION
This way proposed system will try to ease the traffic flow
and will help the ambulance and patients to reach the
destination as early as possible by not getting stuck at road
blocks. This will surely help many ambulances which get
stuck in between traffic and which is risky for patient.Hence
this will save many lives which are lost just because of
ambulance delays.
