1. A RESCUE SYSTEM OF AN ADVANCED
AMBULANCE USING PRIORITIZED
TRAFFICE SWITCHING
PRESENTED BY

2. Introduction
 Traffic congestion and tidal flow management were recognized as
major problems in modern urban areas, which have caused much
thwarting for the ambulance.
 Moreover road accidents in the city have been incessant and to
bar the loss of life due to the accidents is even more crucial. To
implement this we introduce a scheme called AARS (Automatic
ambulance rescue system).

3.  The main theme behind this scheme is to provide a smooth flow
for the ambulance to reach the hospitals in time and thus
minifying the expiration. The idea behind this scheme is to
implement an IT’S which would control mechanically the traffic
lights in the path of the ambulance.
 The ambulance is controlled by the central unit which furnishes
the most scant route to the ambulance and also controls the traffic
light according to the ambulance location and thus reaching the
hospital safely.

4.  The server also determines the location of the accident spot
through the sensor systems in the vehicle which encountered the
accident and thus the server walks through the ambulance to the
spot. This scheme is fully automated, thus it finds the accident
spot, controls the traffic lights, helping to reach the hospital in
time.

5. Existing System Proposed System
 Nowadays the traffic police is manually
control the traffic signal.
 In some places automatic traffic light is
used with auto timer technology.
 Still the traffic is more and there is no
system to reduce the traffic.
Drawbacks of existing system
 If there is no police in the signal traffic
collision will occur.
 The timer technology not suits to all the
traffics.
 We are proposing this system to reduce the
traffic by monitoring the density of the
traffic using image capturing process.
 The higher priority is given to the
ambulance and the ambulance is fixed
with RF transmitters.
Advantages of proposed system
 The traffic clearance is based on density of
the traffic.
 More importance given for ambulance.

6. Working principle
 In proposed system if a vehicle has met accidents, immediately an
alert msg with the location coordinates is sent to the Control center.
From the control center, an msg is sent to the nearby ambulance.
Also signal is transmitted to all the signals in between ambulance
and vehicle location to make it green. The vehicle accident observed
using vibration sensor and in the control section it is received by the
microcontroller and then the nearby ambulance is received from the
PC and controller sends the message to the ambulance. The signal to
Traffic signal section is transmitted through RF communication.
